Israeli fighter jets bombed sites in Yemen affiliated with the Iran-backed Houthi militia on Saturday in retaliation for a deadly drone attack in Tel Aviv a day earlier, the Israeli military said. It was the first time Israel has publicly attacked the group in months of escalating violence.

The airstrikes targeted gas and oil depots and a power station that Israel said were used for military purposes in the area of the Red Sea port of Hodeidah, two regional officials said. The port is controlled by the Houthis and contains oil export facilities.

An Israeli military official, who briefed reporters on the condition of anonymity, called the port a major supply route for Iranian weapons from Iran to Yemen. But it is also a vital conduit for humanitarian aid to impoverished Yemen; the official conceded that Israeli forces had also struck some “dual-use” targets also used for civilian purposes.

A 26-year-old hair braider named Josephine Owino disappeared one morning last month in the sprawling shantytown of Mukuru Kwa Njenga in Kenya’s capital, Nairobi, after going out suddenly to see someone who had just phoned.

Ms. Owino’s younger sister, Peris Keya, was desperate to find her, and went to three police stations pleading for help. But nothing happened until Ms. Keya said she had a startling dream one night: Her sister appeared, led her up a hill and begged her to search in a pool of water.

Since then, at least 10 sacks with body parts have been fished from an abandoned quarry filled with a thick bed of floating trash, according to the police and human rights activists. The dump was searched only because Ms. Keya, 24, beseeched some local men to help, paying them for the grisly task.
