The attack, which follows a series of escalating air assaults on Ukraine in recent weeks, showed the need for "biting" sanctions on the sources of income Russia uses to finance the war, including on those who buy Russian oil, Ukrainian President Volodymyr Zelenskiy said on Telegram.

Russia launched its largest drone and missile bombardment of Ukraine overnight into Wednesday, according to Ukrainian President Volodymyr Zelenskyy.

Ukraine's air force says that Russia has fired a record 728 Shahed and decoy drones at Ukraine overnight as well as 13 missiles. It was the latest escalation amid mounting Russian aerial attacks in the more than three-year war.
