A human rights activist says the death toll is probably much higher

A civilian defense spokesman and human rights activist say Boko Haram militants have killed more than 100 people and hoisted their black and white flag over a town just 85 kilometers from Nigeria’s Maiduguri.
Survivors said Saturday the insurgents lobbed homemade bombs into homes and gunned down people trying to escape Friday’s attack on Damboa.
A human rights activist says the death toll is probably much higher. He spoke on condition of anonymity because he is not authorized to speak to reporters.
Damboa has been under siege for two weeks since Boko Haram dislodged soldiers from a military camp.
Abbas Gava, a local vigilante group spokesman, says hundreds of villagers are also on the run after receiving threatening letters from the Islamic extremists.
