Two bridges have collapsed overnight in separate incidents in Russian regions bordering Ukraine, killing at least seven people and injuring dozens more.

State media said the collapses were being probed as “acts of terrorism”.

A road bridge came down in Bryansk, bringing several heavy trucks onto a moving passenger train late on Saturday, the regional governor said.

At least seven people were killed and at least 71 were injured, Governor Alexander Bogomaz said.

Hours later another bridge collapsed in the Zheleznogorsk district of Kursk, derailing a locomotive train, acting governor Alexander Khinshtein said.

The train caught fire and a driver suffered injuries to his legs, Khinshtein said.

Khinshtein wrote on Telegram in the aftermath: “The cause of the bridge collapse will be established. All emergency services are working on the scene. I am keeping the situation under control.”

Moscow Railway alleged on Telegram that the Bryansk bridge came down as a result of “illegal interference”.

A Ukrainian national security official said the incidents were Russian “false flag” operations, designed to “manipulate international opinion” ahead of peace talks between Russia and Ukraine in Turkey on Monday.

Andrii Kovalenko, head of Ukraine’s National Security and Defence Council’s Centre for Countering Disinformation, accused Russia of “laying the groundwork to derail the negotiations”.

He added Ukraine had “absolutely no incentive to sabotage the Istanbul summit”.

Russian President Vladimir Putin was briefed on the incidents throughout the night, the Kremlin said.

Pictures online from Bryansk showed mangled carriages and passengers helping each other climb out of the wreckage in the dark.

Moscow’s interregional transport prosecutor’s office said an investigation had been launched.

Authorities said the train’s locomotive and several cars derailed when the road bridge fell on to it.

Additional emergency workers, as well as rescue equipment and light towers for carrying out work at night have been sent to the area, according to Russian news agency TASS.

The train was going from the town of Klimovo to Moscow and was in the Vygonichsky district when the collapse happened, officials said.

Passengers were evacuated and guided to a meeting point at a nearby station, Moscow Railway said, adding: “They will be able to continue their journey on a specially formed reserve train” travelling from Bryansk to Moscow.

The first incident took place about 100km (62 miles) from the Ukraine border.

Meanwhile, the Ukrainian Air Force said seven regions were hit by intense Russian strikes overnight on Saturday, with a total of 472 UAV and drone attacks and seven missile strikes.

When Edna Nicole Luckett sings the Blues on the stage at Red’s, her voice, deep and soulful, echoes against the walls. The juke joint in Clarksdale, Mississippi is one of the last of its kind in the region, a landmark for a bygone era of American music.

“I was raised in Delta dirt, sunshine and flatland that goes on for miles and miles,” she sings, as people nod their heads and stomp their feet to the beat.

Ms Luckett, like many who were raised in the Mississippi Delta, grew up listening to locally-crafted Blues music and singing in her church choir. It’s experiences like hers – and places like Red’s – that are getting a fresh moment to shine with the box office success of Ryan Coogler’s film Sinners.

The genre-defying film has earned more than $300 million (£22 million) globally, against a $90m (£67m) budget, and attracted the world’s attention to a historic small town.

For the those who live there – and especially those who still sing the Blues – the spotlight is welcome, in no small part because of Coogler’s careful respect for their history.

“I’m protective of how the Mississippi Delta is represented,” Ms Luckett said.

Clarksdale was the place where blues legends like Sam Cooke, John Lee Hooker and Muddy Waters got their start, but its significance was mostly known to music lovers.

Like other small towns in the US south, Clarksdale has faced struggles. The town, home to 14,000 people, lost its only movie theatre in 2003. That meant that residents couldn’t even watch Sinners in their hometown – until now. After a local appeal, Mr Coogler agreed to bring the film to town for six free showings this past week.

The charge was led by Tyler Yarbrough, a Clarksdale native, who wrote a public letter to the director after seeing the movie in a nearby town. Set in 1932, Sinners tells the story of twin brothers, both played by Michael B Jordan, who return home to Clarksdale after World War One. Combining elements of musicals, horror and period drama, the movie fuses vampire lore with meticulous historic research about that time and place in America.

“Beneath the horror and fantasy, your film captures the soul of this place: our history, our struggles, our genius, our joy, our community,” Mr Yarbrough wrote.

He told the BBC he was moved to see this place represented with careful detail.

“It was time traveling back to 1930’s in Clarksdale, in our town, so this is the lives of my great grandma,” he said. “The history from the farms to the juke joints was on full display.”

Mr Coogler, who also made Black Panther and Creed, said it was his Uncle James, a Mississippi native who loved Delta Blues, who helped inspire the film.

Although the movie was ultimately filmed in Louisiana, he visited Clarksdale to do extensive research.

“I never got to come here until working on this script,” Mr Coogler told a crowd of 1,500 on Thursday. “It blew my mind — I got to meet musicians, I got to meet community members. It really changed me just to come here and do the research.”

While some remnants of the town depicted in the film remain, like many towns in America, its storefronts have been emptied and modernised – though it still enjoys tourist interest for its history.

Odes to some of Clarksdale’s blues legends, like Robert Johnson, are colourfully painted onto the sides of buildings, reminding people of the history of the streets where they walk.

One of those streets used to be home to Delta Blues Alley Cafe, a blues joint owned by Jecorry Miller that burned to the ground last month.

Mr Miller wants people to have a better understanding of the history that lives on the streets on Clarksdale and the movie is a way to grasp that.

“The movie itself is going to be great for the town – we get nine times the population of our city that comes to visit the city every year, now it could be ten or 11 times the population that visits Clarksdale,” Mr Miller said. “People being here spending their dollars is a great thing for us.”

And local residents said the attention is all the more welcome because they see themselves and their culture in the film.

At the Thursday screening, longtime Clarksdale residents relished the details.

Ms Luckett, the Blues singer, was listening to make sure the characters’ dialect sounded right. She watched to see if the land in the backdrop of the film was as flat and green as it is in real life.

“It was,” she said with a smile.

Some 17,000 people have evacuated the Canadian province of Manitoba as fast-moving wildfires move across parts of the country.

A military aircraft and helicopters have been used to evacuate some residents in remote areas as firefighters face growing flames. Hot and dry weather is expected in the coming days.

Dense smoke from the fires – of which there are more than 188 according to officials – has spread across Canada and into parts of the US.

Both Saskatchewan and Manitoba have declared states of emergency for the next month and have asked for international help in fighting the fires.

In Saskatchewan, there are 17 wildfires burning as of Saturday, with eight classified as not contained. The Canadian Interagency Forest Fire Centre (CIFFC) classified conditions in the province as extreme.

Saskatchewan Premier Scott Moe warned at a Saturday news conference that the current figure of 8,000 fire evacuees could climb to 10,000 as dry weather conditions persist.

“The next four to seven days are absolutely critical until we can find our way to changing weather patterns, and ultimately a soaking rain throughout the north,” Mr Moe said.

Large parts of Alberta and British Columbia have also ordered evacuations as the fires spread.

The evacuation of residents of the northern First Nations community of Pukatawagan, is a “rapidly evolving situation”, a Manitoba official told the BBC on Saturday.

Canadian Armed Forces, Manitoba Wildfire Service and Manitoba’s Heavy Urban Search and Rescue Team have been using a military aircraft and helicopters to bring people to safety from the northern community in Manitoba.

“The scale and complexity of these air evacuations cannot be overstated — and neither can the unwavering dedication of the teams executing them,” Prime Minister Mark Carney said on Saturday.

In Flin Flon, a city of 5,000 in Manitoba, only firefighters and support workers are left in the town.

In Manitoba, there are a total of 25 active fires, according to the province’s fire situation report, with 11 classified as out of control.

Danielle Desjardins, a meteorologist with Environment and Climate Change Canada based in Winnipeg, told the BBC that the forecast for both provinces is not promising.

While a cold front is expected to hit some parts of Saskatchewan, it will not bring relief to the regions where fires are burning.

“The bad news about this cold front is it’s going to be windy,” said Ms Desjardins, adding that the wind, coupled with the heat and lack of rain, are prime conditions for wildfire spread.

Smoke from the fires has also left an estimated 22 million Americans under air quality alerts this weekend.

In northern Minnesota, residents have been warned smoke could reach levels “unhealthy for everyone”, while the rest of the state faces air quality warnings for sensitive groups. That alert runs through Monday evening.

Canada experienced its worst wildfire season on record in 2023, when more than 42 million acres (17.3m hectares) burned.

Fires happen naturally in many parts of the world, including in Canada.

But climate change is making the weather conditions needed for wildfires to spread more likely, according to the UN’s climate body.

Extreme and long-lasting heat draws more and more moisture out of the ground and vegetation.

It’s a condition that affects more than 10 million people in the UK. It can change futures, end careers, and shrink worlds. So when a hack comes along that says it can “cure”, or at the very least fend off a migraine, people will try it.

While there are medical treatments, there is no cure. Prescription medication can be very effective – but it doesn’t always work. For many people there is no simple solution.

Some discover their own ways of managing the debilitating pain: blasting the side of their face with a hairdryer, or sitting in a hot bath while wearing an ice pack and drinking a smoothie.

But now a new hack has suddenly gone viral – the McMigraine Meal. A simple offering of a full-fat cola and a portion of salty fries seems to be doing the trick for hundreds who’ve been extolling its virtues on TikTok.

If there is any science behind these hacks – what do they do to the body?

Nick Cook, from Oxfordshire, carries “a wallet full of drugs” around in case of a migraine attack. He will “try anything” to make the pain go away, he says.

“When you live with the condition, and you’re working a five-day week and you need to carry on, you’ll give anything a go.”

At its worst the pain around Nick’s eye socket can feel like his eyeball is getting crushed. He says it’s the caffeine and sugar in cola that helps him.

“If I catch it soon enough it can sometimes work, when my vision goes fuzzy and I can feel one coming on.”

He stresses that drinking cola doesn’t replace his amitriptyline tablets – the daily pain medication he takes to try to prevent migraines – but it does sometimes help him “last until the end of the day”.

For Kayleigh Webster, a 27-year-old who has had chronic migraines all her life, it’s the salt on the chips that might slow down a migraine attack.

“It can help,” she says cautiously, “but it’s certainly not a cure.

“Migraine is a complex neurological condition – and it can’t be cured by a bit of caffeine, salt and sugar in a fast food meal.”

Kayleigh’s tried cocktails of different medications, putting her feet in hot water, a flannel at the back of the head, acupuncture, cupping – but they’ve had little effect.

One of the few treatments that has given her relief is medical Botox – having dozens of injections in her head, face and neck. It’s still not clear how Botox works for migraine, but it’s believed to block powerful pain signals being released from the nerves.

A migraine – which can last days – is very different to a headache, which tend to be short-lived and can be treated more easily with painkillers like paracetamol. Migraines can cause head pain, neck pain, numbness, blurred vision, and even affect speech and movement.

Skulls dating back to 3,000 BC show ancient Egyptians even had trouble with migraines – but despite that long history, their exact cause is still unknown.

It’s thought pain receptors in the blood vessels and nerve tissue around the brain misfire – sending incorrect signals that something is wrong. But we don’t know why some people have an oversensitive nervous system – and why it reacts to some things and not others.

Experts say there’s not enough research into why only some people – around one in seven – are affected, or what can actually help.

Dr Kay Kennis, a trustee for the Migraine Trust and a GP who specialises in migraines, says while there are elements of the McMigraine meal that can help stave off an attack, these aren’t innate to “a McDonald’s”.

“The caffeine in the coke can act as a nerve disruptor, it is a substance that affects nerve activity. For some, that disturbance works in a positive way,” Dr Kennis says.

“There are some painkillers that people take for migraines that have caffeine – and some do respond well to that – but we don’t fully know why.”

But she warns against using caffeinated fizzy drinks like cola as a way of regularly managing migraines.

“Too much caffeine can be a trigger too – and you can end up in a worse situation in the long run,” Dr Kennis says.

Other ingredients in a fast food meal, like the salt on the chips, can affect nerve activity, she explains, but adds the effects of sodium on migraines have not been tested.

She also warns that not only is fast food often ultra-processed and not conducive to a healthy diet, it can contain high levels of Tyramine, a natural compound commonly found in many foods, which can actually cause severe migraines.

For Eloise Underwood none of the quick fixes on social media work.

The chronic migraine sufferer has been looking for a “magic cocktail” for seven years – she’s seen people recommend putting feet in scorching water (not recommended by experts and potentially dangerous); drinking hot coffee (caffeine can be a trigger); or various vibrating devices which have had little effect.

“There are so many videos online that take advantage of the desperation we all feel,” Eloise explains.

She’s left several jobs – often due to lighting and noise in an office environment triggering migraines. She recently stopped working as an interior designer and has now launched a business pressing and framing wedding flowers from her home.

She wears loop ear buds to reduce the sharpness of the sounds around her, and limits her social life.

“People think a migraine is just a headache – that’s just one symptom of it,” Eloise says. “For me, a migraine is a whole body experience…

“Migraines have completely made my life smaller.”

Prof Peter Goadsby, a neurologist at the NIHR-King’s Clinical Research Facility, says research is beginning to produce positive results after years of underfunding.

His latest study shows medications known as gepants could block a group of pain receptors in the lead-up to a migraine attack, cutting off the pain before it starts.

“Any new treatment is a glimmer of hope,” Eloise says. “They do say that nothing will work for everyone – but something will work for someone.”

Lifestyle changes can also make a difference, Prof Goadsby explains. It might be boring, he says, but basically – “be careful of your brain”.

“You want to have regularity, avoid the highs and lows. If you can feel the warning signs – yawning, sleepiness, mood change, passing more urine and even craving salt and sugar – listen to your body.

“Listen to your body – don’t listen to TikTok, that’s my advice.”

Nick has been doing exactly that. He might reach for the odd cola and salty fries, but he’s moulded his whole life in order to manage his migraines.

“I don’t drink, I wear sunglasses even if it’s cloudy,” he says. “I don’t go wild. When me and my partner go away, half the stuff we take is to help us manage our migraines.”

On a recent stag-do weekend, Nick noticed the difference between his and his friends’ lives.

“They were up all night drinking to the early hours,” Nick says. “I turned up with my own pillow, apples, bananas, Weetabix, and any snacks I would need to keep me going, because hunger can be a major trigger.

“I’m in bed by midnight – but my mates know me, and that’s OK, because this is how I have to live my life.”

It was love at first sight for Adarsh Ramchurn. “I couldn’t control it,” he says of his flourishing affection for Nav Sangha.

But their relationship is “frowned upon” by some in their communities, they say, as Adarsh is Hindu and Nav is Sikh.

They’ve been an item for three years and say they receive hateful comments on social media when posting about their life together.

They are also abused because Adarsh, 24, has a darker skin tone than Nav, a form of prejudice known as colourism.

“We push through it,” says Nav, 22. “There are also people who are very supportive and that are in similar situations.”

Data compiled by YouGov in January suggests 45% of 18 to 24-year-olds in the UK believe there is a God, or believe there are Gods. The next highest figure, 36%, is for the over-65s.

BBC News spoke to Nav and Adarsh as well as a Christian from Married At First Sight (MAFS), a Muslim from The Only Way is Essex (Towie), and a former Jehovah’s Witness for the Sex After documentary series.

During a discussion between the participants, Nav was asked what the hardest bit about being a Sikh was. “Probably getting the backlash of being with a Hindu,” she said.

She and Ardash knew their interfaith relationship could be an issue for their parents, so spoke to them early.

“I know it’s different for every family, there can be difficult dynamics,” says Adarsh.

“But if you can have the open discussion [about] dating outside of your religion… I’d always say [you should].”

Something Adarsh’s parents were quick to ask him about was marriage.

The couple say, if they were to wed, they would probably do a Sikh and a Hindu ceremony.

“If we have kids, I feel like it’s important that they learn about both religions and faiths,” Nav adds.

Adarsh agrees and says he’s “looking forward to it”.

Junaid Ahmed’s parents were not as accommodating. His fear of being rejected by them took hold at a young age. Junaid knew being gay contravened the Islamic beliefs he and his family shared.

“When I did finally come out [aged 18], I did expect the worst and… [it] did happen,” he tells us. “They threw me out; they disowned me.”

He says he doesn’t blame his parents for ostracising him.

“I genuinely don’t – it’s made me the person I am today.”

Junaid, now aged 26 and a star of Towie, says he often gets abuse online from other Muslims because he is open about his sexual orientation, but “that [has] never changed my relationship with God”.

He says he is grateful for his religious upbringing and still prays every day.

Like Junaid, Martin Riley – who was brought up a Jehovah’s Witness – was also ostracised by his family.

However, in his case, it was because a few years ago he was expelled from his religion completely, in a process called disfellowshipping.

For Riley, as he is known to his friends, this meant being shunned by other members of his congregation – including close friends and family.

His first marriage, which lasted 20 years, had broken down a few months before he was expelled.

He was a particularly strong believer and, while dating after he was expelled, he abided by the rule of not having sex before marriage.

It was only when Riley began dating the woman who is now his wife, that he began seriously considering whether he wanted to continue adhering to the religion that he’d been part of for 40 years. His wife is not a Jehovah’s Witness.

“I realised that I did not want to have a future that didn’t include her, whether that meant returning to the religion or not.”

After having sex with her for the first time, which he describes as being, “like in the movies”, he recalls: “I was actually surprised by how guiltless I felt about the whole thing.”

Riley, 48, now considers himself an atheist.

Looking back at his expulsion from the religion aged 42, he says: “It was devastating for me, at the time. Now I think it is probably one of the best things to ever happen to me.”

Unlike Riley, Sacha Jones did not grow up devoutly religious, but was baptised as a Christian last year after finding her faith. She has vowed to remain abstinent until she marries.

“I haven’t slept with anyone since my baptism,” she says. “So I’m fresh in the eyes of the Lord!”

Sacha, 30, also says the culture around dating today makes it difficult to form a long-term relationship.

Last year she participated in MAFS, but split up with her partner following the show.

“It’s the absolute trenches out here in the dating world… it’s difficult to trust a man anyway, but then to trust someone that doesn’t fear God as well?”

She says she doesn’t miss sex as much as she might do because she isn’t dating anyone at the moment. She believes the wait will be worth it – once she’s married.

“I no longer lack purpose or peace,” says Sacha, who isn’t the “party animal” she once was. “I’m happier than I’ve ever been.”

Hamas responded to a US ceasefire proposal by saying it is prepared to release 10 living Israeli hostages and 18 dead hostages in exchange for a number of Palestinian prisoners, while requesting some amendments to the plan.

The group repeated its demands for a permanent truce, a complete Israeli withdrawal from Gaza and guarantees for the continuous flow of humanitarian aid. None of these are in the deal on the table.

It was neither an explicit rejection nor a clear acceptance of the US terms, which Washington says Israel has accepted.

Hamas said it had submitted its response to the US draft proposed by Steve Witkoff, US President Donald Trump’s special envoy for the Middle East.

In a statement, Witkoff said: “I received the Hamas response to the United States’ proposal. It is totally unacceptable and only takes us backward. Hamas should accept the framework proposal we put forward as the basis for proximity talks, which we can begin immediately this coming week.

“That is the only way we can close a 60-day ceasefire deal in the coming days.”

A statement from Israeli Prime Minister Benjamin Netanyahu’s office said: “While Israel has agreed to the updated Witkoff outline for the release of our hostages, Hamas continues to adhere to its refusal.”

Hamas, a proscribed terror group in the US, UK and EU, said it was insisting on a “permanent ceasefire” and “complete withdrawal” of Israeli forces from the Gaza Strip.

The group demanded a sustained flow of aid for Palestinians living in the enclave, and said it would release 10 living hostages and the bodies of 18 dead hostages in exchange for “an agreed upon number” of Palestinian prisoners in Israel.

But Hamas now finds itself in the most complex and difficult position it has faced since the war began.

Under intense pressure from 2.2 million people living in the worst conditions in their history and from the mediators, the movement is unable to accept an American proposal that is, by all accounts, less generous than previous offers it has rejected multiple times, the most recent being in March.

At that time, senior Hamas official and head negotiator Khalil al-Hayya stated unequivocally that the movement would not agree to partial deals that fail to secure a complete and permanent end to the war.

Yet, Hamas also finds itself unable to reject the latest US offer outright, fully aware that Israel is preparing to escalate its ground offensive in Gaza.

The movement lacks the military capacity to prevent or even seriously resist such an assault.

Caught between these two realities, Hamas, in effect, responded to the US proposal not with an answer – but with an entirely new counterproposal.

The full details of the US plan have not been made public and are unconfirmed, but these key points are reportedly included:

• A 60-day pause in fighting

• The release of 28 Israeli hostages – alive and dead – in the first week, and the release of 30 more once a permanent ceasefire is in place

• The release of 1,236 Palestinian prisoners and the remains of 180 dead Palestinians

• The sending of humanitarian aid to Gaza via the UN and other agencies

The terms on offer were the ones Israel could accept – the White House made sure of that by getting Israel’s approval before passing the proposal to Hamas.

It is unlikely that Israeli Prime Minister Benjamin Netanyahu will be willing to negotiate the changes Hamas wants.

He is under pressure to bring the hostages home and has said he is willing to accept a temporary ceasefire to do so.

But the Israeli government has always insisted on the right to return to hostilities, despite Hamas’s core demand for guarantees that the temporary truce be a path to ending the war.

Netanyahu has said the war will end when Hamas “lays down its arms, is no longer in government [and] its leaders are exiled from the Gaza Strip”.

Defence Minister Israel Katz was more blunt this week. “The Hamas murderers will now be forced to choose: accept the terms of the ‘Witkoff Deal’ for the release of the hostages – or be annihilated,” he said.

Responding to Witkoff’s latest comments, Hamas official Basem Naim told the BBC the group had last week come to an agreement with him on a proposal “which he deemed acceptable for negotiation” – but that the Israeli response “disagreed with all the provisions we had agreed upon”.

“Why, each time, is the Israeli response considered the only response for negotiation?” he said.

“This violates the integrity and fairness of mediation and constitutes a complete bias towards the other side.”

Earlier on Saturday, the Hamas-run Gaza health ministry said 60 people were killed and another 284 injured in the past 24-hours in Israeli strikes.

That does not include numbers from hospitals located in the North Gaza Strip Governorate because of the difficulty of accessing the area, it adds.

Israel launched a military campaign in Gaza in response to Hamas’s cross-border attack on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.

At least 54,381 people have been killed in Gaza since then, including 4,117 since Israel resumed its offensive on 18 March, according to the Hamas-run health ministry.

Few 27-year-olds look at used cooking oil and see a green business opportunity to produce soap or dog food.

But that is what Hugo Daniel Chávez, a project manager for the NGO Sustenta Honduras, has done.

“We have so many businesses and domestic practices that create waste, so we are trying to transform waste and give it a second life,” he tells the BBC.

Across Latin America, several million tonnes of cooking oil are consumed every year. It is often used to fry food, mostly chicken, plantain strips, chips and pork.

But reusing and heating it too often – as is often the case in Honduras, where there is a huge black market for used cooking oil – can create compounds which are bad for consumers’ health.

Improperly discarded, it can also have a massive detrimental impact on the environment.

If it is drained down the sink, it can damage pipes and contaminate groundwater, and when it is tossed by the side of the road, it can contaminate freshwater and crops many communities rely on.

Faced with these health and environmental hazards, the young green entrepreneurs behind Sustenta tried to come up with a solution which would not only give businesses an incentive to dispose of their oil and grease properly, but also turn these waste products into something useful.

The NGO’s executive director, Ricardo Pineda, explains that their idea originated from earlier efforts by different companies and organisations to transform used cooking oil into biodiesel. “But in Honduras, we don’t have a market for biodiesel,” he says.

“So we decided to produce products that can do well in our domestic markets [such as soap and dog food].”

In order to make it more attractive to people to get rid of the oil legally rather than sell it to unscrupulous buyers, Sustenta offers to buy the used cooking oil and pick it up regularly from the shops that participate in their project.

Their efforts have gained international recognition, most notably when they were awarded a $20,000-prize as one of the winners of the 2023 Youth4Climate Energy Challenge, a global initiative co-led by the Italian government and the United Nations Development Programme.

Sustenta also receives funding from the embassy of the The Netherlands in the region, which told the BBC that it chose Sustenta because “their project offered an innovative and viable solution, using an enterprising approach which has a social impact”.

“It [their project] not only contributes to lessening the environmental impact through an emphasis on creating a circular economy, but also empowers young people and women – the groups most affected by climate change – and generates green jobs.”

Sustenta offers between 2.50 and 3.50 Lempiras (£0.08 and £0.11) per pound of used cooking oil.

And it is not just small businesses it deals with.

In May of 2024, the NGO signed a contract with the Mexican and Central American division of the retail giant Walmart.

This contract guarantees a flow of used cooking oil and grease from all companies related to Walmart to Sustenta, which Mr Pineda says is critical to Sustenta’s project.

“We needed a reliable flow to scale up production. (…) Otherwise, we could quickly run out of used cooking oil, because of the black market that is competing with us,” adds Mr Chávez.

It then brings the cooking oil and grease to a plant in Comayagua, where they are purified and processed in a reaction known as saponification. This process combines fats or oils with an alkali to produce soap.

Mr Pineda says that Sustenta is keen to develop “a circular ecological system in which we reuse everything”.

“Next to our plant that produces the soap and dog food, someone else has a water purification plant and we use the water that plant cannot purify, its waste so to say, for our water cooling system,” he explains.

The idea of teaming up with Walmart, Mr Pineda says, is “to sell the dog food and soap we have refined from their waste at Walmart”.

“They could profit from their own waste and also see the economic value behind circular economies, ” he tells the BBC.

At 15 lempiras (£0.45) per bar of soap, the project makes a monthly revenue of over 106,000 Lempiras (£3,194.70), which excludes fixed costs like salaries, commission and distribution.

Mr Pineda emphasises that “the money doesn’t stay with us”. “We just help with the implementation of the project and as soon as it’s up and running we seek new opportunities,” he says.

The recycling of cooking oil is just one several projects running simultaneously at Sustenta.

The organisation is comprised of young people, all under 30 and averaging 23 years of age, and their youthful enthusiasm and impatience with established ways of doing things has been key to their approach.

“We started as a young group that was sick of the regular ways large institutions handle issues with climate change and the environment,” Mr Pineda says.

“We want to create actual solutions and not sit around only talking about what could be done.”

Their strategy also differs from that of other young environmental organisations in the region, who often focus on a confrontational approach, trying to halt large mining or energy projects and holding politicians accountable for corruption.

But Sustenta’s project coordinator, Paola Acevedo, says the two approached are not at odds, but rather complement each other: “This type of [classical] environmentalism is very important and there is no doubt that we need it.”

“We try to focus on solutions, while the others fight on the front lines,” she adds.

Two people have died and hundreds have been arrested across France after Paris Saint-Germain (PSG) fans celebrated the club’s victory in the Champions League final, according to the French interior ministry.

In the south-west town of Dax, a 17-year-old boy died after being stabbed in the chest late on Saturday evening, local media reported.

A 23-year-old man who was riding a scooter in central Paris was also killed after being hit by a vehicle, the prosecutor’s office said.

Flares and fireworks were set off, bus shelters smashed and cars torched amid wild celebrations as PSG won the biggest prize in European club football for the first time in their history.

Paris police prefect Laurent Nuñez said PSG’s Champions League trophy parade will go ahead on Sunday evening – but there will be an increased police and military presence on the ground.

Nuñez spoke after the French interior ministry said 192 people were injured in the overnight clashes and 559 people arrested, including 491 in Paris.

Twenty-two police officers and seven firefighters were injured, the ministry said, adding that 264 vehicles were set on fire.

Nuñez said: “The toll is lower than what we have seen in the past, but we will never get used to this kind of abuse, with people who only came to commit acts of vandalism and who did not even watch the match, and we will always have a very firm response.”

“This is just half time for us because the PSG players are coming to Paris,” he said, with a celebration expected around the Parc des Princes where players will meet fans.

“There again we are expecting some clashes, some scuffles and we will be there and we will be very strong in our response against the vandals, against the thieves who have a go at the police officers.

“We will not tolerate any abuse today and the fans who want to enjoy the parade, can do so safely.”

He added that “PSG supporters shouldn’t be mixed up with gangs of looters and vandals”.

Separately, the Paris Prosecutor’s Office told the BBC “several shops were looted” in the Place des Ternes area. About 30 people were arrested and taken into custody near a Foot Locker on the Champs-Elysées that was robbed, the office said.

Elsewhere across France, Dax mayor Julien Dubois, reacting to the fatal stabbing, said his “thoughts are with the young victim, his family and friends”.

“We are floored by all the drama tonight,” he wrote on social media. “It is advisable to quickly shed light on these facts in order to severely punish the perpetrator.”

While clashes broke out near the city’s Champs-Élysées avenue and PSG’s Parc des Princes stadium, the majority of fans celebrated PSG’s 5-0 win over Inter Milan peacefully, with many singing and dancing in the streets or blaring their car horns.

The Eiffel Tower was illuminated with PSG’s blue and red colours.

French President Emmanuel Macron, a keen supporter of rivals Olympique de Marseille, posted on X: “A glorious day for PSG! Bravo, we are all proud. Paris, the capital of Europe this evening.”

Approximately 5,400 police were deployed across Paris in anticipation of the raucous celebrations.

At least 300 people detained were suspected of possessing fireworks and causing disorder, Paris police said.

“Troublemakers on the Champs-Elysees were looking to create incidents and repeatedly came into contact with police by throwing large fireworks and other objects,” police said in a statement.

Riot police reportedly used a water cannon to stop a crowd reaching the Arc de Triomphe, and fired tear gas into the crowds.

Other clashes between police and crowds occurred on the Paris ring road. At least two cars were torched near the Parc des Princes.

French Interior Minister Bruno Retailleau took a hard line against the disorder, writing on social media: “True PSG supporters are enjoying their team’s magnificent match.

“Meanwhile, barbarians have taken to the streets of Paris to commit crimes and provoke the police.

“It’s unbearable that it’s unthinkable to party without fearing the savagery of a minority of thugs who respect nothing.”

Meanwhile, outside Paris, police said a car ploughed into PSG fans in Grenoble in south-east France, leaving four people injured.

All those hurt were from the same family, police said. Two were seriously injured.

The driver handed himself into the police and was placed under arrest. A source close to the investigation told the AFP news agency it was believed the driver had not acted intentionally.

The trophy parade in central Paris – scheduled for 17:00 local time (16:00 BST) – will run for one hour from the Champs Elysees to the Arc de Triomphe.

After the parade, the PSG players and staff will be received at the Élysée Palace and later on Sunday evening the trophy will be presented in front of season ticket holders at the Parc des Princes.

Two bridges have collapsed overnight in separate incidents in Russian regions bordering Ukraine, killing at least seven people and injuring dozens more.

State media said the collapses were being probed as “acts of terrorism”.

A road bridge came down in Bryansk, bringing several heavy trucks onto a moving passenger train late on Saturday, the regional governor said.

At least seven people were killed and at least 71 were injured, Governor Alexander Bogomaz said.

Hours later another bridge collapsed in the Zheleznogorsk district of Kursk, derailing a locomotive train, acting governor Alexander Khinshtein said.

The train caught fire and a driver suffered injuries to his legs, Khinshtein said.

Khinshtein wrote on Telegram in the aftermath: “The cause of the bridge collapse will be established. All emergency services are working on the scene. I am keeping the situation under control.”

Moscow Railway alleged on Telegram that the Bryansk bridge came down as a result of “illegal interference”.

A Ukrainian national security official said the incidents were Russian “false flag” operations, designed to “manipulate international opinion” ahead of peace talks between Russia and Ukraine in Turkey on Monday.

Andrii Kovalenko, head of Ukraine’s National Security and Defence Council’s Centre for Countering Disinformation, accused Russia of “laying the groundwork to derail the negotiations”.

He added Ukraine had “absolutely no incentive to sabotage the Istanbul summit”.

Russian President Vladimir Putin was briefed on the incidents throughout the night, the Kremlin said.

Pictures online from Bryansk showed mangled carriages and passengers helping each other climb out of the wreckage in the dark.

Moscow’s interregional transport prosecutor’s office said an investigation had been launched.

Authorities said the train’s locomotive and several cars derailed when the road bridge fell on to it.

Additional emergency workers, as well as rescue equipment and light towers for carrying out work at night have been sent to the area, according to Russian news agency TASS.

The train was going from the town of Klimovo to Moscow and was in the Vygonichsky district when the collapse happened, officials said.

Passengers were evacuated and guided to a meeting point at a nearby station, Moscow Railway said, adding: “They will be able to continue their journey on a specially formed reserve train” travelling from Bryansk to Moscow.

The first incident took place about 100km (62 miles) from the Ukraine border.

Meanwhile, the Ukrainian Air Force said seven regions were hit by intense Russian strikes overnight on Saturday, with a total of 472 UAV and drone attacks and seven missile strikes.

Two Scottish men have been killed in a shooting at a bar in southern Spain, according to Spanish officials.

A gunman fired several shots at Monaghans Bar in Fuengirola in Andalusia on Saturday evening before fleeing the scene.

Javier Salas from the central government in the Malaga province confirmed to BBC News both men were believed to be Scottish.

Spanish media reported that officers from the region’s specialist and violent crime unit are leading the investigation.

Regional newspaper Diario Sur reported the attack took place just after 23:00 when a car pulled up and a masked man opened fire.

They said both men died at the scene, and the gunman fled in the vehicle.

Monaghans is located on the seafront and is a popular bar with tourists and expats.

The bar had been screening the UEFA Champions League final on the evening of the attack.

Police are yet to make any arrests but have not ruled out that the killings were linked to organised crime.

Police Scotland said it was unable to comment on a possible link to a recent gangland feud in Scotland, and directed inquiries towards the Spanish authorities.

BBC journalist Guy Hedgecoe said there had been a number similar shootings in the Costa del Sol area in recent weeks, several of which are believed to have some kind of connection to drug crime.

The Foreign Office said it had not been approached for any consular assistance but that its staff stood ready to assist any British nationals if required.

It was love at first sight for Adarsh Ramchurn. “I couldn’t control it,” he says of his flourishing affection for Nav Sangha.

But their relationship is “frowned upon” by some in their communities, they say, as Adarsh is Hindu and Nav is Sikh.

They’ve been an item for three years and say they receive hateful comments on social media when posting about their life together.

They are also abused because Adarsh, 24, has a darker skin tone than Nav, a form of prejudice known as colourism.

“We push through it,” says Nav, 22. “There are also people who are very supportive and that are in similar situations.”

Data compiled by YouGov in January suggests 45% of 18 to 24-year-olds in the UK believe there is a God, or believe there are Gods. The next highest figure, 36%, is for the over-65s.

BBC News spoke to Nav and Adarsh as well as a Christian from Married At First Sight (MAFS), a Muslim from The Only Way is Essex (Towie), and a former Jehovah’s Witness for the Sex After documentary series.

During a discussion between the participants, Nav was asked what the hardest bit about being a Sikh was. “Probably getting the backlash of being with a Hindu,” she said.

She and Ardash knew their interfaith relationship could be an issue for their parents, so spoke to them early.

“I know it’s different for every family, there can be difficult dynamics,” says Adarsh.

“But if you can have the open discussion [about] dating outside of your religion… I’d always say [you should].”

Something Adarsh’s parents were quick to ask him about was marriage.

The couple say, if they were to wed, they would probably do a Sikh and a Hindu ceremony.

“If we have kids, I feel like it’s important that they learn about both religions and faiths,” Nav adds.

Adarsh agrees and says he’s “looking forward to it”.

Junaid Ahmed’s parents were not as accommodating. His fear of being rejected by them took hold at a young age. Junaid knew being gay contravened the Islamic beliefs he and his family shared.

“When I did finally come out [aged 18], I did expect the worst and… [it] did happen,” he tells us. “They threw me out; they disowned me.”

He says he doesn’t blame his parents for ostracising him.

“I genuinely don’t – it’s made me the person I am today.”

Junaid, now aged 26 and a star of Towie, says he often gets abuse online from other Muslims because he is open about his sexual orientation, but “that [has] never changed my relationship with God”.

He says he is grateful for his religious upbringing and still prays every day.

Like Junaid, Martin Riley – who was brought up a Jehovah’s Witness – was also ostracised by his family.

However, in his case, it was because a few years ago he was expelled from his religion completely, in a process called disfellowshipping.

For Riley, as he is known to his friends, this meant being shunned by other members of his congregation – including close friends and family.

His first marriage, which lasted 20 years, had broken down a few months before he was expelled.

He was a particularly strong believer and, while dating after he was expelled, he abided by the rule of not having sex before marriage.

It was only when Riley began dating the woman who is now his wife, that he began seriously considering whether he wanted to continue adhering to the religion that he’d been part of for 40 years. His wife is not a Jehovah’s Witness.

“I realised that I did not want to have a future that didn’t include her, whether that meant returning to the religion or not.”

After having sex with her for the first time, which he describes as being, “like in the movies”, he recalls: “I was actually surprised by how guiltless I felt about the whole thing.”

Riley, 48, now considers himself an atheist.

Looking back at his expulsion from the religion aged 42, he says: “It was devastating for me, at the time. Now I think it is probably one of the best things to ever happen to me.”

Unlike Riley, Sacha Jones did not grow up devoutly religious, but was baptised as a Christian last year after finding her faith. She has vowed to remain abstinent until she marries.

“I haven’t slept with anyone since my baptism,” she says. “So I’m fresh in the eyes of the Lord!”

Sacha, 30, also says the culture around dating today makes it difficult to form a long-term relationship.

Last year she participated in MAFS, but split up with her partner following the show.

“It’s the absolute trenches out here in the dating world… it’s difficult to trust a man anyway, but then to trust someone that doesn’t fear God as well?”

She says she doesn’t miss sex as much as she might do because she isn’t dating anyone at the moment. She believes the wait will be worth it – once she’s married.

“I no longer lack purpose or peace,” says Sacha, who isn’t the “party animal” she once was. “I’m happier than I’ve ever been.”

Indian singer Diljit Dosanjh’s Met Gala debut last month left a lasting impression on global fashion.

The 41-year-old singer, who is the only Punjabi musician to perform at Coachella, walked the red carpet dressed like an early 20th Century maharajah.

His opulent ivory and gold ensemble – created by designer Prabal Gurung – complete with a feathered bejewelled turban, trended in India for weeks.

He also wore a gorgeous diamond necklace, its design inspired by a Cartier piece worn by an erstwhile king of the northern Indian state of Punjab.

A Panthère de Cartier watch, a lion-headed and a jewel-studded sword completed the ensemble, which had a map of Dosanjh’s home state embroidered on the back of the cape along with letters from Gurmukhi, the script for Punjabi language.

Of course, Dosanjh is no stranger to such style.

Just like his music, he’s carved out a niche in fashion too – a hip hop singer who is known for melding traditional Punjabi styles with Western influences.

Often seen in anti-fit trousers, chunky sneakers, and stacks of necklaces that he matches with his colourful turbans, his unique form of self-expression has captured the imagination of millions, leading to interesting reinventions in the traditional Punjabi attire.

The changes can be felt everywhere. A 16-minute high-intensity bhangra competition in California would be impossible without high performance sneakers. And basement bhangra nights in Berlin are enjoyed in crop tops and deconstructed pants.

Punjabi music itself, high on volume and energy – with lyrics packed with the names of cities and global luxury brands – has become a subculture.

It’s not just Dosanjh – several other Punjabi musicians have also influenced the region’s style game.

Not long ago, Punjabi-Canadian singer Jazzy B’s rings, often the size of a cookie, along with his plus-sized Kanda pendant and silver blonde hair tints, were trending.

More recently, the yellow tinted glasses worn by singer Badshah; the baggy hoodies sported by Yo Yo Honey Singh; and AP Dhillon’s Louis Vuitton bombers and Chanel watches have been hugely popular with Punjabi youth.

But even though their influence was significant, it was restricted to a region. Dosanjh and a few others like him, however, have managed to mount it to a global level, their style speaking to both the Sikh diaspora as well as a broader audience. For instance, the t-shirts, pearls and sneakers Dosanjh wore to his world tour last year were sold out in a matter of hours. Dhillon’s style statements at Paris Couture Week have created aspiration among Punjabi youth.

Cultural experts say that this reinvention, both in music and fashion, has its roots in Western pop-culture as most of the artistes live and perform in the West.

“Punjabi men are inventive. The region has been at the forefront of fusion, it believes in hybridity. This is especially the case with the Punjabi diaspora – even when they live in ghettos, they are the showmen [of their lives],” says art historian, author and museum curator Alka Pande.

Over the years, as the Punjabi diaspora community grew, a new generation of musicians began mixing modern hip-hop sounds with elements of traditional Punjabi aesthetics.

Their distinct style lexicon – of gold chains, faux fur jackets, plus-sized accessories, braids and beards – went on to spawn media articles, books and doctoral theses on South Asian culture.

The coin dropped instantly back home in Punjab, which absorbed logo fashion like a sponge when luxury brands arrived in the 2000s. For Punjabis – who are largely a farming community – it was an aspirational uprising, symbolic of how success and prosperity should look.

“It symbolised the movement of the Punjabi identity from a farmer to a global consumer,” says acclaimed singer Rabbi Shergill.

Arguing that performers, like everyone else, are a product of their times, Shergill says these impulses are “a response to the hyper capitalist world”.

Curiously, the style game of Punjabi musicians – from hip-hop, R&B, bhangra pop, fusion, Punjabi rap, reggae or filmy music – has also remained rooted and androgynous, instead of being hyper masculine.

A pop star may wear Balenciaga or Indian designer Manish Malhotra’s opulent creations; perform anywhere from Ludhiana city to London; dance with Beyonce around Dubai’s Burj Khalifa, atop a luxury car, or in a British mansion – but they always wear their Punjabi identity on their sleeves.

Dosanjh underlined this clearly with his maharajah look at the Met Gala. “It’s like the popularity of his androgynous style was waiting to happen,” Pande says.

The composite impact of this trend on emerging artists is unmissable today in Punjab.

Local Bhangra performances, for instance, are no longer limited to traditional “dhoti-kurta-koti” costume sets paired with juttis (ethnic footwear). Performance attire now includes sneakers, typographic T-shirts, deconstructed bottoms and even denims.

“Such items are highly sought after by customers,” says Harinder Singh, owner of the brand 1469.

The merchandise in Singh’s stores, includes accessories popularised by Punjab’s music stars, such as versions of Phulkari turbans worn by Dosanjh, Kanda pendants that were first popularised by veteran Bhangra artist Pammi Bai. Singh himself owns turbans in more than a 100 shades.

Even overall men’s style in Punjab bears some of this cosmopolitan twang.

Young poet Gurpreet Saini, who performs at cultural festivals across India, says he sources his shawls – printed with ombre Gurmukhi letters – from Hariana, his hometown in Punjab, for a distinctive look. He admits to the influence of music icons, including those like folk singer Gurdas Mann, who he grew up watching.

What began as personal flair in some cases, went on to become fashion statements. Now these choices are cultural signatures. They have recast the Punjabi identity through rhythm, hybridity as well as a rooted sense of self.

Two people have died and hundreds have been arrested across France after Paris Saint-Germain (PSG) fans celebrated the club’s victory in the Champions League final, according to the French interior ministry.

In the south-west town of Dax, a 17-year-old boy died after being stabbed in the chest late on Saturday evening, local media reported.

A 23-year-old man who was riding a scooter in central Paris was also killed after being hit by a vehicle, the prosecutor’s office said.

Flares and fireworks were set off, bus shelters smashed and cars torched amid wild celebrations as PSG won the biggest prize in European club football for the first time in their history.

Paris police prefect Laurent Nuñez said PSG’s Champions League trophy parade will go ahead on Sunday evening – but there will be an increased police and military presence on the ground.

Nuñez spoke after the French interior ministry said 192 people were injured in the overnight clashes and 559 people arrested, including 491 in Paris.

Twenty-two police officers and seven firefighters were injured, the ministry said, adding that 264 vehicles were set on fire.

Nuñez said: “The toll is lower than what we have seen in the past, but we will never get used to this kind of abuse, with people who only came to commit acts of vandalism and who did not even watch the match, and we will always have a very firm response.”

“This is just half time for us because the PSG players are coming to Paris,” he said, with a celebration expected around the Parc des Princes where players will meet fans.

“There again we are expecting some clashes, some scuffles and we will be there and we will be very strong in our response against the vandals, against the thieves who have a go at the police officers.

“We will not tolerate any abuse today and the fans who want to enjoy the parade, can do so safely.”

He added that “PSG supporters shouldn’t be mixed up with gangs of looters and vandals”.

Separately, the Paris Prosecutor’s Office told the BBC “several shops were looted” in the Place des Ternes area. About 30 people were arrested and taken into custody near a Foot Locker on the Champs-Elysées that was robbed, the office said.

Elsewhere across France, Dax mayor Julien Dubois, reacting to the fatal stabbing, said his “thoughts are with the young victim, his family and friends”.

“We are floored by all the drama tonight,” he wrote on social media. “It is advisable to quickly shed light on these facts in order to severely punish the perpetrator.”

While clashes broke out near the city’s Champs-Élysées avenue and PSG’s Parc des Princes stadium, the majority of fans celebrated PSG’s 5-0 win over Inter Milan peacefully, with many singing and dancing in the streets or blaring their car horns.
