A pall of acrid smoke hung over Kyiv on Friday morning following a night of intensive Russian strikes that hit almost every district of the capital, according to Ukrainian authorities.

The hours of darkness were once again punctuated by the staccato of air defence guns, buzz of drones and large explosions. Ukraine said Russia had fired a record 550 drones and 11 missiles during a long night of bombardment.

The strikes came hours after a phone call between Donald Trump and Vladimir Putin, after which the US president said he was "disappointed" that Putin was not ready to end Russia's war against Ukraine.
