Overnight, Ukrainian drones attacked one of the largest arsenals in Russia, causing a powerful detonation in the town of Toropets in Russia's Tver Oblast, a source in the Security Service of Ukraine (SBU) told the Kyiv Independent.

Local authorities have partially evacuated residents of Toropets in Russia’s Tver Oblast after a mass drone attack overnight caused a large fire, Tver Oblast Governor Igor Rudenya claimed on Sept. 18.

Russia said it was working to repel a Ukrainian drone attack on Toropets, where there's a major military depot, as explosions lit up the night.

A Ukrainian drone attack launched overnight destroyed an ammunition depot in the western Russian region of Tver, a source from Ukraine’s Security Service told CNN.

Ukraine said Thursday its air defenses shot down all 42 drones that Russia used in overnight attacks targeting regions across the country. Ukraine’s air force said it also shot down a Russian guided missile.

Ukraine's air force said on Thursday it had shot down all 42 drones and one of four missiles used by Russia during overnight attacks.
