Human rights activists have condemned the killing of a young woman in Cameroon’s Anglophone regions after a video of alleged separatist rebels slitting her throat drew outrage on social media.

The conflict between separatists demanding independence from the mostly Francophone state and government forces has killed more than 3,000 people since 2017, with both sides regularly accused of committing atrocities.

In the video, a young woman is seen with her hand behind her back being accosted by several young men, who then slit her throat with a machete and dump her body in the middle of the road.

The Cameroon-based Centre for Human Rights and Democracy in Africa (CHRDA) said in a report that the victim was a 35-year-old mother of four. It said she was killed on Tuesday in the town of Muyuka by separatist fighters who accused her of spying for the government after she spent the weekend with a soldier.

CHRDA director Felix Agbor Nkongho told Reuters the incident spoke to a deteriorating security situation in the English-speaking Southwest and Northwest Regions.

“There is an escalation of crimes against civilians, especially women,” he said.

Ilaria Allegrozzi, a senior researcher for Human Rights Watch, said she was investigating the incident and called on separatist leaders and their supporters to “stop these atrocities and attacks against civilians”.

The leader of the main armed separatist faction, Julius Ayuk Tabe, could not be immediately reached for comment. Separatist leaders have in the past denied similar accusations.

Last week, a Cameroonian humanitarian worker was killed in the Northwest Region, said a statement by the U.S. embassy that called for an independent investigation.

Representatives of Cameroon’s government-held their first peace talks with Tabe and the other main leaders of the insurgency last month, but no meetings have been reported since.
