Moscow regards Ukraine's firing of ATACMS and Storm Shadow missiles into Russia as proof of direct U.S. and British involvement in the war.

Dnipro appeared to bear the brunt of Moscow's first retaliatory strike after Ukraine fired U.S.-made missiles into Russia, but it's unclear what weapons Russia used.

The Ukrainian Air Force said that Russia launched the ICBM at the centrally located city of Dnipro from its southeastern Astrakhan region, several hundred miles away. Kyiv's Center for Strategic Communication and Information Security said it's the "first time in history" that this weapon was fired in a war.
