At least 19 people have been killed and dozens more wounded in a shooting at a college in Russian-annexed Crimea.
An 18-year-old student ran through the technical college in Kerch firing at fellow pupils before killing himself, Russian investigators say.
Officials and witnesses have also spoken of at least one blast caused by an unidentified explosive device.
The alleged perpetrator, named Vladislav Roslyakov, is reported to have run from room to room as he fired, starting in the canteen. He then shot himself dead, Russia’s investigative committee said.
Officials said initial examinations suggested all the victims died of gunshot wounds, but some reports speak of shrapnel injuries.
Soon after reports of a blast, investigators released a statement saying an explosive device filled with “metal objects” had detonated in the dining area.
