Officials in south-western Cameroon say suspected separatist rebels have killed at least 20 people during an overnight attack on a village.

Several others were left badly injured and homes were set ablaze in the area known as Manyu.

Two Anglophone regions of Cameroon have suffered from relentless violence since 2017 when separatists started fighting government troops.

Rights groups have accused both sides of committing widespread atrocities during the conflict.

It's left at least 6,000 people dead and close to a million others displaced.
