More than 80 people, mostly children, have been kidnapped from a school in the city of Bamenda in western Cameroon, government and military sources said.
So far no one has claimed responsibility for the abduction in the English-speaking region where separatists are fighting to form a breakaway state.
The separatists have imposed curfews and closed down schools as part of their protest against President Paul Biya's French-speaking government.
"In total 81 people were kidnapped including the principal. They were taken to the bush," a military source told Reuters.
A government spokesman said it was keeping track of an event but that it could not comment further.
The separatist movement gathered pace in 2017 after a government crackdown on peaceful demonstrations. Many people have fled Bamenda and other centres to seek refuge in more peaceful Francophone regions.
Last week, anti-government demonstrations took place in France and the US in protest over the presidential election in Cameroon which they say was rigged by the incumbent.
