(Reuters) - At least three people were killed and dozens of residential buildings damaged in the Russian city of Belgorod near the Ukraine border, the regional governor said, in what Moscow said was a Ukrainian missile attack.

At least 11 apartment buildings and 39 private houses were damaged, including five that were destroyed, Governor Vyacheslav Gladkov posted on the Telegram messaging app.

"I emphasise that this missile attack had been intentionally planned and was launched at the civilian population of Russian cities," Russian Defence Ministry spokesman Igor Konashenkov said.

There was no immediate comment from Ukraine.

Konashenkov said Russian air defences had destroyed three Tochka-U missiles, but fragments of one of them fell on residential buildings. He said they had also destroyed explosives-laden Ukrainian drones approaching Kursk, another city in southern Russia.

Reuters could not independently confirm the claims.

Since Russia invaded its neighbour on Feb. 24, there have been numerous reports of attacks on Belgorod and other regions bordering Ukraine, with Moscow accusing Kyiv of carrying out the strikes.

Ukraine has not claimed responsibility but has described the incidents at weapons stores and other sites as "karma" for Russia's invasion.
