Rights group Amnesty International is calling on the government in Cameroon to ensure government soldiers as well as separatists are held accountable for crimes committed in the country's Anglophone regions.

Violence in the North-West and South-West regions of the country escalated two years ago, following protests by local communities that the authorities were discriminating against them.

Amnesty says it has evidence soldiers have destroyed entire villages and tortured detainees; it also accuses the separatists of killing soldiers and targeting teachers and students.

The rights group says the military's heavy-handed response is likely to further alienate Anglophone communities and fuel more unrest.
