Russian air defenses downed 21 Ukrainian drones in the space of an hour late on Tuesday, most over western Bryansk region, the Russian Defense Ministry said.
The ministry, in a post on Telegram, said air defence units had downed 20 drones between 9:30 p.m. and 10:30 p.m. (1830 and 1930 GMT) over the Bryansk region on the Ukrainian border.
One drone was downed over Crimea, annexed by Russia in 2014 after a popular uprising forced a pro-Russian president to flee Ukraine.
