The Cameroonian military has withdrawn from the north-western town of Belo after it was attacked by anglophone separatists, known as the Ambazonians.
The move follows weeks of military raids in English-speaking parts of Cameroon. Homes have been burned and many people arrested.
On Wednesday, fighters - believed to be separatists - killed the headmaster and teacher of a school and cut off a student's hand.
A BBC correspondent in Cameroon says the school was attacked because it failed to heed the separatists' call to shut down in protest against marginalisation by the francophone majority.
