The death toll from a Russian missile attack that flattened a Kyiv apartment building has risen to 24. It was one of the deadliest attacks on the capital in the 4-year-old war. Ukrainian President Volodymyr Zelenskyy said three teenagers were among the victims. He led an official day of mourning Friday in Kyiv, a day after the Russian cruise missile struck the nine-story corner block amid what the Ukrainian air force said was Russia’s biggest barrage of the country since its full-scale invasion in 2022. Throughout the day, people came to the rubble-strewn site to leave bouquets and stuffed toys. Zelenskyy said Thursday's assault mostly targeted the Ukrainian capital, where 48 people were wounded.
