A skyscraper in Russia’s capital Moscow has been hit again by a drone, Mayor Sergei Sobyanin says.

Several drones were shot down overnight, he said, but “one flew into the same tower at the Moskva City complex” that was targeted on Sunday.

The building’s facade was damaged on the 21st floor, the mayor says. No injuries have been reported.

Russia blamed Ukraine for several such attacks in recent months. Kyiv usually makes no public comment on the issue.
