People run for cover in Kremenchuk park as missile hits mall

STORY: The ground shook and people fell as debris fell from the air, and a tree shed its leaves while one person threw themselves into the park's lake.

A day after the attack in which at least 18 people were killed, the city of Kremenchuk in central Ukraine declared a day of mourning and firefighters cleared away rubble.

Russia said the incident was caused by a strike on a legitimate military target. Its defense ministry, quoted by the RIA state news agency, said Russian forces had fired missiles at a storage depot for Western weapons in Kremenchuk, and the detonation of stored ammunition there had caused the fire at the nearby mall.

Russia denies intentionally targeting civilians in its "special military operation" in Ukraine, which has destroyed cities, killed thousands of people and driven millions from their homes.
