The strike, against an ammunition depot, comes days after the U.S. authorized the use of ATACMS on Russian territory.

Russia has said Ukraine fired US-supplied long-range missiles into the country for the first time on Tuesday. Ukraine used Atacms missiles in a strike on Russia's Bryansk region this morning, the ministry of defence in Moscow said.

Ukraine fired U.S.-made long-range missiles inside of Russia on Tuesday for the first time since a restriction was lifted by Washington, according to Russian officials. The Russian Ministry of Defense said in a Telegram post that a facility was struck in the Russian region of Bryansk with the Army Tactical Missile System (ATACMS) long-range missiles.
