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 missile Russia used to strike Dnipro on the morning of 21 November was an "experimental medium-range ballistic missile", not an intercontinental ballistic missile (ICBM). Source: CNN, citing a US official,
