A Ukrainian drone attack Wednesday sparked a large fire and forced a partial evacuation in an area of Russia’s Tver region.

The attack happened in the town of Toropets, with Ukrainian security sources saying the drones destroyed a Russian arms warehouse storing missiles and artillery.

Igor Rudenya, Tver’s governor, did not specify the site of the fire, but said on Telegram the situation was “under control.”

Russia’s Defense Ministry said Wednesday it destroyed 54 Ukrainian drones overnight, including 27 over the Kursk region, 16 over Bryansk, seven over Smolensk, three over Belgorod and one over Oryol. Officials in those regions did not report any serious damage or casualties.

Ukraine has repeatedly targeted border regions such as Bryansk, Kursk and Belgorod. The attack on Tver, about 500 kilometers from the border, is not as common, but is an example of what Ukrainian officials have repeatedly said they want to do in order to hit Russian military infrastructure that could be used to attack Ukraine.

Ukraine’s military said Wednesday that Russia’s latest round of overnight attacks included three guided missiles and 52 aerial drones.

Ukrainian air defenses shot down 46 of the 52 drones, with intercepts taking place over the Cherkasy, Kherson, Kirovohrad, Kyiv, Mykolaiv, Poltava, Sumy and Vinnytsia regions, the military said.
