Suspected Boko Haram militants have killed at least 45 people in a village in Borno state, north-east Nigeria, witnesses have said.
Gunmen stormed Njaba and fired into the houses before setting the village on fire, survivors added.
The raid happened early on Tuesday but was not reported until a day later because of the remoteness of the area.
Boko Haram has killed thousands of people in its drive to establish an Islamic state.
