Myo Zaw and his team of volunteer rescue workers were the first to arrive at the site where a three-story house had collapsed in Mandalay, a little after 8 p.m. on Saturday. They were digging through the rubble with their bare hands when they heard the voice of a girl.

It was faint but clear. “Help me, I’m here,” she said.

It took them three or four hours to pull out the 12-year-old, who had survived despite the house toppling around her. But in the early hours of Sunday morning, there was only silence as the rescuers continued to work in nearly 100-degree heat. They eventually unearthed three bodies: the girl’s mother and her grandparents.

“Sadly, I fear we will find more bodies than survivors,” Mr. Myo Zaw said. “The heat in Mandalay is intense, causing rapid decomposition. In some cases, we locate the bodies only because of the smell.”

Time is running short in Mandalay, Myanmar’s second-largest city with about 1.5 million people, which is near the epicenter of Friday’s devastating earthquake. In one neighborhood in Mandalay, countless buildings were reduced to rubble, satellite images showed.

Across the country, over 1,600 people were confirmed dead, as of Saturday night, and over 3,000 injured in the worst earthquake to hit Myanmar in more than a century. Many fear that the number of people who can be rescued will dwindle after Monday evening, the crucial 72-hour mark after which experts say the chances of survival drop sharply.

China, Russia and India have dispatched emergency teams and supplies to earthquake-ravaged Myanmar. So have Thailand, Malaysia and Vietnam.

The United States, the richest country in the world and once its most generous provider of foreign aid, has sent nothing.

Even as President Trump was dismantling the U.S. Agency for International Development, he said that American help was on its way to Myanmar, where a 7.7-magnitude earthquake ripped through the country’s heavily populated center on Friday. More than 1,700 people were killed, according to Myanmar’s military government, with the death toll expected to climb steeply as more bodies are uncovered in the rubble and rescue teams reach remote villages.

But a three-person U.S.A.I.D. assessment team is not expected to arrive until Wednesday, people with knowledge of the deployment efforts said. The overall American response has been slower than under normal circumstances, people who have worked on earlier disaster relief efforts as well as on aid to Myanmar said.

Chinese search-and-rescue teams, complete with dogs trained to sniff out trapped people, are already on the ground in Mandalay, Myanmar’s second-largest city and one of the places most deeply affected by the quake. China has pledged $14 million for Myanmar quake relief, sending 126 rescue workers and six dogs, along with medical kits, drones and earthquake detectors.

“Being charitable and being seen as charitable serves American foreign policy,” said Michael Schiffer, the assistant administrator of the U.S.A.I.D. bureau for Asia from 2022 until earlier this year. “If we don’t show up and China shows up, that sends a pretty strong message.”

Marine Le Pen, the French far-right leader, has tried and failed three times to become president. Now, even as her popularity rises, she may be barred from taking part in an election to lead France if she is found guilty of embezzlement on Monday.

Such a verdict, far from certain, has been equated by Ms. Le Pen with a “political death” sentence and a “very violent attack on the will of the people.” It would ignite a major political storm at a time when the French Fifth Republic has appeared increasingly dysfunctional.

On the one hand stands the principle, as Nicolas Barret, one of the prosecutors, put it in closing arguments last year, that “We are not here in a political arena but a legal one, and the law applies to all.”

On the other hand lies the fear, expressed by some leading politicians, that a ban would undermine French democracy by feeding a suspicion that it is skewed against the growing forces of the hard right.

“Madame Le Pen must be fought at the ballot box, not elsewhere,” Gérald Darmanin, a former center-right interior minister, wrote on X in November. He is now the justice minister.

Ms. Le Pen, 56, has steered her anti-immigrant party from its antisemitic roots toward the mainstream. The party, whose name she changed from the National Front to the National Rally, is now the largest single party in the National Assembly with 123 seats.

Quakers in Britain are reeling from what they say is an unheard-of violation of one of their places of worship by police officers who forced their way into a meeting house in London and arrested activists gathered there to plan Gaza war protests.

“No one has been arrested in a Quaker meeting house in living memory,” Paul Parker, the recording clerk for Quakers in Britain, said in a statement issued after the raid.

But on Thursday evening, the pacifist group said, more than 20 uniformed police officers, some armed with tasers, forced their way into the meeting house in Westminster, breaking open the front door “without warning or ringing the bell.”

The officers searched the building and arrested six women at a gathering of Youth Demand, an unaffiliated activist group that was renting a room to meet in, the Quakers in Britain said.

The Metropolitan Police said the arrests followed Youth Demand’s plans to “shut down” London with protests next month, according to British media. The police said that while they recognized the right to protest, “we have a responsibility to intervene to prevent activity that crosses the line from protest into serious disruption and other criminality,” British media reported.

The arrests raised alarms in England, and came amid a crackdown on Gaza War protesters in the United States, especially on college campuses, where some students have denounced Israel’s prosecution of the war against Hamas.

Secretary of Defense Pete Hegseth wrapped up his first official visit to Asia on Sunday by offering reassurances to Japan that President Trump wants a stronger military alliance in the region to deter an increasingly assertive China.

Following an 85-minute meeting in Tokyo with his Japanese counterpart, Mr. Hegseth said the Trump administration would abide by promises to increase security cooperation with its staunch ally. This would include speeding up a Biden administration-era plan to create a new joint U.S.-Japan military command in Tokyo that he called a “war-fighting headquarters,” although Mr. Hesgeth did not say when it would become operational. He also said there would be more joint military exercises in the Okinawa islands near Taiwan, a self-ruled island that China says is part of its territory and has threatened to take by force.

Mr. Hegseth arrived in Japan from the Philippines, another U.S. ally, where the defense secretary also sought to allay anxiety about the Trump administration’s commitment to the region. Japan has watched with concern as the United States has broken with traditional allies in Europe to seek a deal that might allow Russia to keep territory seized from Ukraine.

Japanese officials have worried in private that such concessions might encourage China to make a move on Taiwan. After the meeting with Gen Nakatani, the Japanese defense minister, Mr. Hegseth struck a strident tone about the alliance, proclaiming that the United States would work with Japan to secure “peace through strength” that will deter the Chinese from taking action.

“America first does not mean America alone,” Mr. Hegseth told reporters. “America and Japan stand firmly together in the face of aggressive and coercive actions by the communist Chinese.” Mr. Hegseth did not address concerns about his sharing of military information on the Signal chat app that included a journalist.

Israel and Hamas both signaled over the weekend that efforts for a renewed cease-fire in Gaza were underway, less than two weeks after the breakdown of a temporary truce and the resumption of Israel’s air and ground campaign against the militant group in the enclave.

Hamas said on Saturday that it had accepted a proposal for a new cease-fire, which would see some hostages released from captivity in Gaza. Israel said it, too, had received a proposal via third-party mediators and had responded with a counterproposal in coordination with the United States.

“The military pressure is working,” Prime Minister Benjamin Netanyahu of Israel said on Sunday in remarks at the start of his weekly cabinet meeting, adding that Israel was “suddenly seeing cracks” in Hamas’s position.

Since Israel resumed attacks on the Gaza Strip on March 18, over 900 people have been killed, the enclave’s health ministry said on Saturday. The ministry does not distinguish between civilians and combatants.

Neither side published details of the proposal or the counterproposal, but an official briefed on the talks suggested that they broadly echoed previous proposals floated in recent weeks. While there was no indication that a breakthrough was imminent, the public statements suggested that after weeks of fruitless negotiations, contacts over a deal were proceeding even as the war continued.

On Sunday, the Palestine Red Crescent Society said it had recovered the bodies of eight emergency medical technicians, five Civil Defense personnel and a United Nations employee in Rafah in southern Gaza. The medical organization said it had lost contact with nine of its crew members more than a week ago after they were directly fired upon by Israeli forces. The Israeli military did not immediately respond to a request for comment.

A video that circulated widely on the internet recently showed a Haitian gang leader, Joseph Wilson, shirtless, happily showing off belts of .50 caliber ammunition, mockingly saying he used the armor-piercing bullets to groom his hair.

“We have enough combs for our hair to last a year,” he joked.

So how did he get them?

Guns are not manufactured in Haiti, and it’s illegal to ship any there, but the gangs terrorizing the country’s capital, Port-au-Prince, never seem to be short of them — or of ammunition.

Experts estimate that there are about 20 armed groups operating in Port-au-Prince, some who carry AR-15 and Galil assault rifles, shotguns and Glock handguns. The U.N. estimates that between 270,000 and 500,000 firearms are circulating illegally in Haiti, with most weapons in the hands of gangs.

Their superior fire power has overwhelmed the thin ranks of Haiti’s ill-equipped police and contributed to an astonishing death toll last year of more than 5,600 homicide victims, a jump of more than 1,000 from the year before.

The United Nations imposed an arms embargo on Haiti three years ago, yet most weapons on Haiti’s streets are from the United States, where they are purchased by straw buyers and smuggled into the country by sea or sometimes by land through the Dominican Republic, according to the United Nations.

The issue has become so serious that Haiti’s government has restricted imports along its land border with the Dominican Republic. Only goods that were originally produced there are allowed; any products that didn’t originate in the D.R. have to enter through Haiti’s gang-infested seaports.
