A Russian drone attack late on Thursday set buildings ablaze in Ukraine's southeastern city of Zaporizhzhia, injuring 29 people, regional governor Ivan Fedorov said.
He said Russian forces had made at least 10 strikes on the city, damaging private homes, tens of high-rise apartment buildings, educational institutions and infrastructure sites.
Three people were rescued from the rubble and 12 people were being treated in hospital, Fedorov added.
The Ukrainian air force said it shot down 64 of 150 drones launched by Russia overnight. Another 62 drones did not reach their targets, likely due to electronic warfare countermeasures, it said.
It did not specify what happened to the remaining 24 drones.
Pictures posted online showed a building ablaze and rescue teams making their way through rubble and clambering up the side of damaged buildings on extended ladders. One picture showed a rescue team carrying an injured man to safety.
Ukraine's state-owned railway Ukrzaliznytsia said the attack on Zaporizhzhia also damaged its locomotive repair plant, an enterprise which specialises in the repair of passenger electric locomotives.
The plant will not be able to function anymore due to significant damage, Fedorov said in televised remarks.
