The Ukrainian capital, Kiev, has come under a massive attack from Russian drones and missiles, officials said.
Tymur Tkachenko, the head of the capital's military administration, said on early Thursday that debris from falling drones had struck buildings in different districts of the city, including residential buildings.
Unofficial Telegram channels posted videos of parts of apartment buildings ablaze. There were no immediate reports of casualties.
Ukraine's air force also said Russian missiles had targeted other regions in the country, including Kharkiv, Sumy and Chernihiv in northern Ukraine and the central region of Poltava.
Kiev's Mayor, Vitali Klitschko, also said that the capital came under heavy Russian attack.
"The enemy is striking Kiev with UAVs and ballistic missiles," the mayor, Vitali Klitschko, wrote on Telegram, adding the capital was "under heavy enemy attack".
Klitschko said on Thursday the attacks on Kiev damaged a five-storey residential building and caused a vehicle to catch fire in a car park.
He said rocket debris also fell on "a non-residential building".
