Russia pounded Ukraine with hundreds of drones and missiles on Friday in the largest aerial attack of the three-year war — just hours after President Trump admitted he was “disappointed” with his call with Russian President Vladimir Putin.

A total of 539 drones and 11 missiles were fired at Kyiv over a seven-hour onslaught — injuring at least 23 people and damaging scores of buildings across the capital, Ukraine’s air force said.

President Volodymyr Zelensky, who is due to speak to Trump later Friday about the war, slammed the attack as “deliberately massive and cynical.”
