Christians warn they are the main target of ongoing violence in Nigeria's restive northeast.
Meanwhile, Brig. Gen. Chris Olukolade, a military spokesman, says its forces have successfully engaged a large number of heavily armed terrorists during the last few days in an effort to curtail the violence.
To date 17 deaths have been reported, 14 suspected Islamic extremists and three soldiers. Twenty others have been arrested.
The spokesman also says Boko Haram extremists are fleeing to Nigeria's borders with Cameroon, Chad and Niger, though that has not been confirmed.
Nigerian President Goodluck Jonathan is attempting to regain control in Adamawa, Borno and Yobe by putting those states under emergency rule.
The president has called for the arrest of anyone suspected of working with the insurgents and ordered his forces to occupy any building housing extremists.
