A witness and officials say at least 20 people have been killed in an attack by Islamic extremists on a military base in north-east Nigeria.
The attack happened in the village of Monguno, some 125 miles from the city of Maiduguri.
Military spokesman Lt Col Sagir Musa said in a statement all those killed were believed to be fighters from the radical Islamic terrorist network Boko Haram.
However, witnesses said at least one of the dead appeared to be a civilian.
Military officials in Nigeria routinely downplay civilian casualties.
Boko Haram and its splinter groups are waging a bloody guerrilla campaign against Nigeria's weak central government.
