Russia has launched 479 drones against Ukraine in the biggest overnight drone bombardment of the three-year war, according to the Ukrainian air force.

The air force said early on Monday that it had downed 460 drones as well as 19 missiles launched overnight.

Russia’s continued to step up its drone and missile attacks on Ukraine, despite declaring, under pressure from United States President Donald Trump, that it is interested in pursuing peace talks. The record launch came just ahead of the start of a prisoner swap agreed at recent talks between the pair.

Of the hundreds of projectiles fired at numerous targets, only 10 reached their destination, Kyiv officials said. One person was reported injured.

Russia’s escalation of aerial attacks has been matched by a renewed battlefield push in the eastern and northeastern parts of the roughly 1,000km (621-mile) front line in occupied parts of Ukraine.
