Dozens of people, mostly school pupils, have been kidnapped from a boarding school in the west of Cameroon.
At least 79 students and three others, including the principal, were seized early on Monday morning in Bamenda, the capital of the North-West region, a government official has told the BBC.
Regional governor Adolphe Lele L'Afrique blamed separatist militias.
Cameroon's North-West and South-West regions have been hit by a secessionist rebellion in recent years.
One student, who managed to avoid capture by hiding under a bed, told the BBC that events unfolded quickly as the kidnappers entered the school.
"One of my friends, they beat him mercilessly. All I could think about was to just stay quiet. They threatened to shoot some people ... all the big boys they rounded up, and the small ones they left them behind."
A teacher at the school described what she saw as she entered the principal's office after students had been taken from different dormitories.
"The military came in and went to the principal's house where we realised that her door was bashed and entered into, the glasses are still there on the ground," she told the BBC.
'Praying for the kidnapped'
The moderator of the Presbyterian Church in Cameroon, the Right Reverend Fonki Samuel Forba told the BBC that he had spoken to the kidnappers.
"They don't want any ransom. All they want is for us to close the schools. We have promised to close down the schools," he said.
"We hope and pray they release the kids and the teachers," he added.
A government official later said a massive search had been launched for the hostages involving the Cameroonian army. "Every man has been called in," the official said, according to AFP news agency.
It is not the first time students have been abducted in the area, known to be a stronghold of separatist fighters, reports the BBC's Ngala Killian Chimtom.
On 19 October, five students of the Atiela Bilingual High School were taken by unidentified gunmen. Their whereabouts are still unknown.
The separatists say that the Cameroon school system suppresses the English-speaking system that the North-West and South-West regions inherited from the British.
The militias, who want to create Ambazonia, began to emerge in 2017 after a security force crackdown on mass protests, led by lawyers and teachers, over the government's alleged failure to give enough recognition to the English legal and education systems in the North-West and South-West.
The government was accused of relying heavily on people trained in the French legal and educational tradition to work in key posts and generally marginalising Cameroon's English-speaking minority, who make up about 20 percent of the population.
President Paul Biya, who has been in power since 1982, was recently re-elected for a seventh term with more than 70 percent of the vote.
Opposition parties allege that the poll was rigged, but legal attempts to overturn the result failed.
Cameroon - still divided along colonial lines
- Colonised by Germany in 1884
- British and French troops force Germans to leave in 1916
- Cameroon is split three years later - 80 percent goes to the French and 20 percent to the British
- French-run Cameroon becomes independent in 1960
- Following a referendum, the (British) Southern Cameroons join Cameroon, while Northern Cameroons join English-speaking Nigeria
