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.

The drone blew out a wall and surrounding windows in the building in Sumy, a major city, just after 1 a.m., the Sumy regional administration said.

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.
