MOSCOW, June 23 (Reuters) - Russia said on Sunday that the United States was responsible for a Ukrainian attack on the Russian-annexed Crimean peninsula with five U.S.-supplied missiles that killed at least five people including three children and injured 124 more.

The Russian Defence Ministry said four of the U.S.-delivered Army Tactical Missile System (ATACMS) missiles, equipped with cluster warheads, were shot down by air defence systems and the ammunition of a fifth had detonated in mid-air.
