The Nigerian military says it has killed around seventy fighters from the Islamic group Boko Haram, during an attack by the militants on the north-eastern town of Bama.
A spokesman for an anti-Boko Haram vigilante group said most of Bama's residents have fled to Borno's state capital, Maiduguri - around 70 kilometres away.
A report last month by Amnesty International said four-thousand people - mostly civilians - have been killed this year in the conflict between Boko Haram and the security forces
