Ukraine’s capital Kyiv is again under a massive overnight Russian drone attack, local officials say, with at least 13 people reported injured and fires burning across the city.

Authorities in Kyiv say drone wreckage has hit the roof of a residential building in the central Shevchenkivskyi district.

Footage on social media, as yet unverified by the BBC, shows explosions in the night sky, as air defence units begin repelling the attack. Ukraine’s military has also warned of a threat of a ballistic missile attack.

Last night, Ukraine reported the biggest ever aerial attack from Russia, after 728 drones and 13 cruise or ballistic missiles struck cities around the country in multiple waves.

In the early hours of Thursday morning, Kyiv’s military administration reported Russian drone strikes in six city districts.

“Residential buildings, vehicles, warehouses, office and non-residential buildings are burning,” administration head Tymur Tkachenko said in a post on Telegram.

He urged city residents to shelter until the air raid siren was lifted.

Overnight, Ukraine’s air force reported a threat of Russian drone attacks in a number of regions. It was not immediately clear whether there were any casualties outside Kyiv.

Russia’s military has not commented on the reported latest attack.
