Russia pummelled Kyiv with drones in an all-night attack, injuring at least 23 people, damaging railway infrastructure and setting buildings and cars on fire throughout the city, authorities in the Ukrainian capital said early on Friday.

Russia launched 550 drones and missiles across Ukraine overnight in the largest aerial assaults since the war began. The capital Kyiv was the primary target.

For months the talk in Kyiv was of a much-anticipated Russian offensive that would aim to gobble up more of Ukraine’s eastern regions. So far, it’s been underwhelming – but the Russians have made some gains and vastly reinforced their troop numbers in some areas.
