Aleppo, Syria—Syrians await treatment on September 24 at a makeshift hospital after airstrikes. Following the collapse of a weeklong cease-fire, Syrian and Russian forces stepped up their assault on the rebel-held section of Aleppo, pounding the city with airstrikes that residents said killed hundreds of people. Syria Civil Defense, a rescue organization also known as the White Helmets, said three of its facilities were “deliberately targeted” from the air. At an emergency meeting of the U.N. Security Council, Britain accused Russia of backing Syria in its perpetration of war crimes.
