Russian drones struck several regions across Ukraine overnight, killing 8 people, including four in Kharkiv, where two residential buildings were hit in a double attack that Volodymyr Zelenskyy called despicable”, writes Radio Liberty.

Three of the 4 killed in Kharkiv were rescue workers who responded to the first attack and were hit by a second strike, said Governor Oleh Synyehubov on Telegram. At least 12 people were injured, and three of them were in serious condition, he said.

“A despicable and cynical attack, when the rescuers arrived at the scene of the strike, the terrorists attacked again”, - wrote Zelenskyy on X, formerly Twitter.

Kharkiv Mayor Ihor Terekhov published photographs on Telegram showing damage to a 14-floor apartment building, as well as damaged emergency vehicles.
