Blast in northeast Nigeria bus station kills 15 - official

ABUJA (Reuters) - A blast in bus station in the northeast Nigerian city of Gombe on Monday killed at least 15 people and wounded 21, an official from the national emergency services said.

The cause of the blast was not immediately clear but Islamist group Boko Haram has repeatedly set off bombs targeting civilians, especially in the remote northeast where it is trying to carve out an Islamist state.
