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.

Russia launched an extensive drone strike on Ukraine’s capital, Kyiv, with the assault lasting over five hours, according to city officials. Several waves of explosions were heard throughout the night as Ukraine’s air defenses intercepted and downed all drones targeting the capital,
