A Russian drone struck a multi-storey apartment building in the northeastern Ukrainian city of Sumy early on Thursday, killing nine people and injuring 13, including a child, President Volodymyr Zelenskiy said.

Officials say a Russian drone has blasted a hole in an apartment building in northeastern Ukraine during a nighttime attack that killed at least six people and wounded nine others.

Ukraine’s Defense Forces downed 37 drones Russian invaders had launched at Ukraine since Wednesday night. Another 39 drones serving as decoys to exhaust Ukraine’s air defenses eventually disappeared from radar.
