Ukraine used U.S. ATACMS missiles to strike Russian territory on Tuesday, taking advantage of newly granted permission from the outgoing administration of U.S. President Joe Biden on the war's 1,000th day.

Russia said its forces shot down five of six missiles fired at a military facility in the Bryansk region. Debris of one hit the facility, starting a fire that was swiftly put out and caused no casualties or damage, it said.

Ukraine said it struck a Russian arms depot about 110 kilometers inside Russia, an attack that caused secondary explosions. Ukraine's military did not publicly specify the weapons used, but a Ukrainian government source and a U.S. official confirmed it had used ATACMS.
