At least 22 people have been killed in an attack on a village in north-west Cameroon, the UN says.
Over half those killed in Ntumbo were children, and local media report that several victims were burned alive.
No-one has claimed responsibility for Friday’s incident, but an opposition party blamed the army.
Cameroon’s government, which has been fighting separatists in the region for three years, has not yet commented on the attack.
James Nunan, an official from the UN’s humanitarian coordination agency OCHA, told the BBC that a pregnant woman was among those killed.
Fourteen children, including nine under the age of five, were also among the dead, he said.
Mr Nunan said the incident has “terrified” the local population.
“Whichever group has done this has threatened that there will be more violence ahead,” he said. “The people we’ve spoken with are extremely traumatised and didn’t expect this.”
In a statement, one of the country’s main opposition parties — The Movement for the Rebirth of Cameroon — blamed “the dictatorial regime” and the head of Cameroon’s security forces for the attack.
Agbor Mballa, a leading figure in the separatist movement, also suggested “state defence forces were responsible”.
An army official, interviewed by AFP news agency, denied the allegations.
The conflict has been centred in north-western Cameroon, where most of the population speaks English because of old colonial ties to Britain.
Armed separatist groups began to emerge in 2017 after a security force crackdown on protests. Separatists have declared independence for a new state they call Ambazonia, but Cameroon’s President Paul Biya has labelled the groups as “terrorists”.
More than 3,000 people have died since the outbreak of fighting and at least 70,000 people have also been displaced from their homes.
