Suspected Boko Haram militants have killed at least 64 people in a village in Borno state, north-east Nigeria, the BBC quoted witnesses as saying on Friday.
The gunmen who stormed Njaba targeted men and boys before setting the village on fire, survivors added.
The raid on Njaba came as many villagers were attending morning prayers, a witness said.
Boko Haram has killed thousands of people in its drive to establish an Islamic state.
