Russian authorities said that a missile launched from a US-supplied MGM-140 ATACMS system by Ukrainian forces exploded overhead and released bomblets across the area - in the water and on land - killing five and injuring 124 people, including children. The CCTV footage captures the moment when the missile's submunitions rain down over the crowded beach, appearing to confirm Russia's allegation that a cluster bomb warhead was used.

Hundreds of people can be seen fleeing for their lives, and some are still in the water, when the bomblets start to impact both the water and the beach. One bomblet is seen almost scoring a direct hit on the lifeguard stand.

"According to latest reports, as a result of the shelling attack on Sevastopol by Ukrainian nationalists, 124 people, including 27 children, received wounds or injuries," Russian health minister Alexey Kuznetsov had announced.

Newsweek summarizes of Crimean official statements of the deadly attack:

The event was caused by Russian air defenses shooting down a series of cluster warhead missiles, one of which altered course as a result. The Russian ministry of defense said that four out of the five missiles launched were shot down, adding: "Another missile, as a result of the impact of air defense systems at the final stage, deviated from the flight path with the warhead exploding in the air over the city."

"The detonation of the fragmentation warhead of the fifth American missile in the air led to numerous casualties among civilians in Sevastopol."
