Ukraine said on Wednesday that at least three people were killed and over 60 others injured in an overnight Russian drone attack on the city of Kharkiv.

"As of now, 64 people have been reported injured, including 9 children. Tragically, three people were killed. My condolences to their families and loved ones," President Volodymyr Zelenskyy said in a statement on X.

Arguing that further pressure must be imposed on Russia, Zelenskyy said the current pressure directed toward Moscow is "not enough" and that they must not be afraid of or postpone "new decisions that could make things more difficult for Russia."

"Without this, they will not engage in genuine diplomacy. And this depends primarily on the United States and other world leaders. Everyone who has called for an end to the killings and for diplomacy must act," he added.

Earlier, Kharkiv Governor Oleh Synyehubov said that two people had died and 60 others injured due to the attack, which he said targeted Kharkiv’s Slobidskyi and Osnovianskyi districts,

Claiming that 15 drones were launched by Russia on the city, Synyehubov said nine apartment buildings, as well as three private houses, 13 cars, and a factory, were also damaged in the attack.

Separately, Kharkiv Mayor Ihor Terekhov said the attack took place between 00.31 to 00.40 am local time Wednesday (2131-2140GMT Tuesday), with emergency services and volunteers working to help alleviate the situation.

Ukraine’s Air Force later claimed on Telegram that its air defenses intercepted 49 of 85 drones launched by Russia overnight.

Kharkiv, Ukraine’s second-largest city, about 30 kilometers (18.6 miles) from the Russian border, has been regularly targeted by airstrikes in the ongoing conflict.

Russian authorities did not immediately comment on Ukraine’s claims.
