At least four people were killed in overnight Ukrainian drone attacks across Russia, officials said, with dozens of others reported injured.

Authorities in the three regions bordering Ukraine — Belgorod, Bryansk and Kursk — reported four civilian deaths and around 30 injuries in small towns and villages from overnight or early Monday morning Ukrainian strikes.

In the Bryansk region, a firefighter was killed while responding to a fire.

Moscow region Governor Andrei Vorobyov said several homes and civilian infrastructure sites in the Podolsk, Domodedovo and Odintsovo districts were set ablaze and damaged during overnight attacks. He did not reveal the nature of the damage or the locations.

At least 10 people, including a child, were wounded, Vorobyov added.
