A Ukrainian drone attack has killed three people in the central Russian city of Ryazan, damaged high-rise apartment buildings and hit an industrial enterprise, Regional Governor Pavel Malkov said early on Friday.
"To our great regret, three people have been killed and 12 injured, including children," Malkov wrote on the Telegram messaging app.
Malkov said the drones damaged two high-rise apartment blocks. He said debris from falling drones also fell on the territory of an industrial site, which he did not identify.
The unofficial Telegram site Mash showed pictures of smoke rising from a high-rise building and said one of the entrances to the building was blocked, preventing residents from leaving.
Other unofficial sites showed several apartments ablaze.
Ryazan, located some 200 km southeast of Moscow, is the site of a large oil refinery.
