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.
Kyiv is now able to strike deeper into Russia using the missiles, including around the Kursk region, where Ukrainian forces hold over 1,000 sq km of territory. Ukrainian and US officials reportedly expect a counter-offensive in the region.
Ukraine’s military earlier confirmed that it had struck an ammunition warehouse in the Russian region of Bryansk, but it did not specify whether Atacms were used.
