YAOUNDE (Reuters) - At least five people were killed in a suicide bomb attack on Sunday in the northern Cameroon town of Mora, military sources said, in what appeared to be the latest cross-border attack by Nigeria's Boko Haram Islamist militant group.

The dead included two civilians and the two female suicide bombers, who detonated themselves at around 8 am (0700 GMT) when they were stopped by a police officer near the entrance to the town. The police officer was also killed.
