A pall of acrid smoke hung over the Ukrainian capital on Friday morning following hours of nightfall punctuated by the staccato of air defence guns, buzz of drones and large explosions. Ukraine said Russia fired a record 539 drones and 11 missiles.

Russia pummeled Kyiv with the largest drone attack of the war, hours after President Donald Trump spoke to Russia's Vladimir Putin, officials said.

KYIV, Ukraine -- Russia targeted Ukraine overnight with 322 drones, 292 of which were "neutralized" by being either shot down or supressed by other means, according to the Ukrainian air force. Eleven people, including two children, were injured in the Kharkiv area, in a drone strike overnight there, according to local emergency services.
