Moscow said Tuesday that Ukraine had attacked Russian soil for the first time with U.S.-supplied ATACMS long range missiles, a day after U.S. President Joe Biden reportedly gave his permission for the weapons to be used.

The announcement comes shortly after Washington lifted restrictions on Ukraine using U.S.-made longer-range missiles.

The Ukrainian military has crossed another one of Russia’s red lines by using long-range U.S.-made ATACMS missiles in the Bryansk region, located roughly 400 kilometers southwest of Moscow. According to the Ukrainian Ministry of Defense — which did not confirm the use of these missiles specifically — the strike targeted a Russian military facility.
