Russian forces launched a new drone assault across Ukraine overnight on Wednesday, killing three people and wounding 64 others, Ukrainian officials said. One of the hardest-hit areas was the city of Kharkiv in northeastern Ukraine, where 17 attack drones struck two residential districts, Mayor Ihor Terekhov said.

Emergency crews, municipal workers and volunteers worked through the night to extinguish fires, rescue residents from burning homes, and restore gas, electricity and water services. “Those are ordinary sites of peaceful life… those that should never be targeted,” Terekhov said.

Moscow’s forces have launched waves of drones and missiles in recent days, with a record bombardment of almost 500 drones on Monday and a wave of 315 drones and seven missiles overnight on Tuesday.
