Ukrainian officials said Russia launched dozens of attack drones and ballistic missiles at Kyiv overnight in one of the biggest combined aerial attacks on the Ukrainian capital of the three-year war, damaging several apartment buildings and injuring at least 15 people.

In the early hours of the morning, witnesses saw and heard successive waves of drones flying over Kyiv, and a series of explosions jolted the city.

The capital also reverberated with the sound of anti-aircraft batteries trying to bring down the drones.

Pictures posted online showed smoke billowing from the top of one block of flats and flames leaping from part of another as emergency crews trained water on it.

An orange-red glow lit up the city as plumes of smoke wafted across the horizon.

By morning, the Kyiv city military administration reported damage in six districts of the Ukrainian capital, and a total so far of 14 people wounded. (Reuters)
