Three civilians were killed on Wednesday evening in a suicide attack in the extreme north of Cameroon.

Security sources said the civilians were killed when a vigilante tried to stop a suicide bomb explosive device from detonating.

The incident took place in Djakana, a village near the boarder with northeastern Nigeria, a stronghold of the Islamist group, Boko Haram which last year pledged allegiance to the Islamic state group.

A source close to the regional authorities in the area said four people were killed in the incident while a few numbers of people were wounded adding that one of them was in critical condition.

According to the source, the bomber had been planning to detonate the explosive in the nearby town of Mora on Thursday, a market day, but his plans were thwarted in Djakana where he had planned to spend the night.

Another three civilians were killed and 20 others wounded in another suicide bombing in Mora on August 21.

Mora is home to the headquarters of a multi-national force fighting Boko Haram.

Boko Haram’s seven-year insurgency has killed at least 20,000 people in Nigeria and border areas of neighbouring Niger, Chad and Cameroon.
