An estimated 1,710 of the warheads that can be used by the Russian military are deployed on the likes of intercontinental ballistic missiles or at strategic bomber bases, the organization said. The U.S. has approximately 1,670 deployed strategic warheads, according to the FAS.

Russian Foreign Minister Sergei Lavrov says "we are strongly in favor of doing everything not to allow nuclear war to happen." This after Russian President Vladimir Putin signed a doctrine to lower the threshold for using atomic weapons.

The attack, using U.S.-supplied ATACMS missiles, is a signal the West wants to heighten the conflict, says Moscow's foreign minister.

Ukraine hit a Russian weapons arsenal with US-made ATACMS missiles that it fired across the border for the first time, according to two US officials, in a major escalation on the 1,000th day of war.

Ukraine used U.S. ATACMS missiles to strike Russian territory for the first time on Tuesday, Moscow said, in an attack regarded by Russia as a major escalation 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,

The attack came just days after President Biden gave Ukraine permission to use the weapons to strike targets inside Russia.

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