At least one person has been killed after Russia launched its largest drone attack on Ukraine since the beginning of its invasion, Ukrainian officials said Wednesday, just hours after US President Donald Trump pledged more military support for Kyiv and accused his Russian counterpart Vladimir Putin of throwing “bullsh*t” over peace talks.

Russia ratcheted up air attacks by drones and missiles on Ukraine this week. The increase comes as President Trump has expressed frustration at Russian President Vladimir Putin's seeming unwillingness to enter talks to end the war.

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

Russia fired a record 728 Shahed and decoy drones at Ukraine overnight, as well as 13 cruise and ballistic missiles, the Ukrainian air force said, in the latest escalation after weeks of mounting Russian aerial and ground attacks in the more than three-year war.

Ukrainian officials say that Russia pounded the capital with yet another mass missile and drone attack, causing fires across the city and injuring at least 10 people a day after the heaviest aerial attack of the war so far.

KYIV, Ukraine — Russia fired more than 100 drones at civilian areas of Ukraine overnight, authorities said Monday, as the Kremlin dismissed the country’s transport chief after a weekend of travel chaos when Russian airports grounded hundreds of flights due to the threat of Ukrainian drone attacks.
