Yaoundé, January 18 (RHC)-- At least four people have lost their lives and two sustained injuries in a bomb attack targeting a mosque in Cameroon’s northern region, a security source says.

According to the source, whose name was not cited in reports, a witness had noticed the suspicious behavior of a young boy arriving in the village on foot and had tried to intercept him. He said that the bomber ran towards the mosque, where he set off the explosives he was carrying with him.

No group or individual has so far claimed responsibility for the deadly incident, but the Takfiri Boko Haram terrorist group, which is based in neighboring Nigeria, has carried out similar attacks in Cameroon.

Over 100 people have reportedly been killed in the far north of Cameroon in about 20 bomb blasts blamed on the Boko Haram since July. Cameroon has joined a regional military alliance alongside Niger, Chad and Nigeria in the battle against Boko Haram.
