Speaking French with Cameroonian accents, the men kill the group after accusing them of belonging to the jihadist group Boko Haram.
As a campfire burns in a remote village on Cameroon's northwestern border with Nigeria, seven men and five boys roast cocoa yam for supper.
The war against Boko Haram has strained local communities, given rise to humanitarian crises and highlighted the need for longer-term development.
"The information we are getting is that the Cameroonian military is finding it difficult to fight the separatists. The military were not prepared for this kind of combat,"
Fifty armoured vehicles and assault weapons were deployed by the government in the English-speaking regions - specifically Bole in the Southwest.
"Many people have lost trace of their relatives, I have not seen my father and my mother. I have not seen them since yesterday when they started chasing us. Everywhere there are military men. Please, people should help me. Young boys are being killed. They abduct some, now everybody is in the bush," amfe resident Peter Ayuk said.
