A Russian missile strike on a crowded shopping mall in the central Ukrainian city of Kremenchuk has killed at least 16 people, an emergency services official said early Tuesday.

"As of now, we know of 16 dead and 59 wounded, 25 of them hospitalized. The information is being updated," emergency services chief Sergiy Kruk said.

Kruk said the rescue work, debris removal and extinguishing of fires were ongoing after Monday's attack.
