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.

Summary

Ukraine fired US-made ATACMS missiles into Russia’s Bryansk region, marking the first time Ukraine has used these longer-range weapons to strike targets deep inside Russia.

The attack comes after the Biden administration authorized Ukraine to use these weapons against targets inside Russia.

In response, President Putin updated Russia’s nuclear doctrine, labeling aggression from non-nuclear states supported by nuclear powers as a joint attack on Russia.
