Debris from destroyed Russian drones sparked park and grass fires in Kiev, the mayor of the Ukrainian capital said on Monday, in what was Moscow's third drone attack on the city in as many nights. "Emergency crews have been dispatched," Mayor Vitali Klitschko said on the Telegram messaging app.

In renewed Russian airstrikes, houses in six districts of the Ukrainian capital Kiev have been damaged by debris from drones shot down by air defences overnight on Friday into Saturday. Kiev Mayor Vitali Klitschko spoke of at least two people being injured in the wave of attacks in a post on his Telegram channel.

A Russian air attack on Kyiv damaged buildings, roads and several power lines in the city, the capital's military administration said early on Sunday, after the military said air defences were trying to repel a drone attack.
