Russia says Ukraine has fired US-supplied long-range missiles into the country, a day after Washington gave its permission for such attacks.

Ukraine used the Army Tactical Missile System (Atacms) in a strike on Russia’s Bryansk region this morning, the ministry of defence in Moscow said.

Five missiles were shot down and one damaged, with its fragments causing a fire at a military facility in the region, it said in a statement.

The strike represents the first time the long-range missiles have been used on Russia’s internationally-recognised territory and comes shortly after Washington signalled Ukraine had permission to fire the Atacms into Russia.
