KYIV, May 14 (Reuters) - Russia attacked the Ukrainian capital Kyiv with drones and missiles early on Thursday, officials said, injuring at least four people and damaging several buildings, including one which partially collapsed with residents likely trapped under rubble.
Tymur Tkachenko, head of the capital's military administration, said part of a residence had collapsed in the eastern Darnytskyi district.
"People are trapped under the rubble," Tkachenko wrote on Telegram. "Emergency services are on their way to the site."
He said four people had been injured in the attack.
Mayor Vitali Klitschko said nine people were being treated in hospital and two others received outpatient treatment.
Tkachenko said buildings had sustained damage in other widely separated city districts including one where drone debris had fallen on the roof of a residential building.
Klitschko also reported damage to buildings throughout the capital, including debris that struck two buildings in a northern suburb, sparking a fire in a 12-storey block of flats.
Reuters TV footage showed emergency crews making their way carefully over piles of rubble while smoke billowed from a wrecked section of an apartment block.
Other video footage on unofficial Telegram channels showed parts of apartment buildings ablaze.
An air raid alert remained in force in the capital more than four hours after it had been imposed.
Ukraine's air force said Russian drones remained outside Kyiv and other regions in central and eastern Ukraine.
On Wednesday, Russia unleashed a daytime drone attack on the country, targeting critical infrastructure in western regions and killing at least six people, officials said.
