Watch: The moment a drone hits Moscow skyscraper

A drone has hit an unfinished building in Russia's capital Moscow.

A second attack happened a few hours later near the Ukrainian border in the Belgorod region killing at least three people, Russian officials say.

Belgorod's Governor, Vyacheslav Gladkov, blamed Kyiv for the attack.

But Kyiv has not claimed responsibility for either incident. It rarely comments on attacks inside Russia.
