Kerch Blast: Crimea College Bomb Attack Kills 18 bbc.com

At least 18 people have been killed and dozens more wounded in an explosion at a college in Russian-annexed Crimea.

Officials said an "unidentified explosive device" detonated at the technical college in Kerch, where Russia has built a bridge between the peninsula and Russia.

Initial reports had suggested that the blast was some sort of gas explosion.

But a Russian national guard official said the incident was a deliberate "terrorist act".
