Clashes between Nigerian troops and Islamist militants in the northeastern city of Damaturu have killed at least 50 people in the last few days, according to reports.
Militants with the Boko Haram group reportedly attacked Damaturu with explosives and gunfire, and battled with Nigerian security forces who dislodged them from a hideout in the north of the city, an army official told reporters in Abuja, the capital.
Bomb attacks and gun battles have also been reported in the cities of Maiduguri and Potiskum.

Boko Haram, which means “Western education is a sin,” claimed responsibility for a suicide car-bomb attack on the United Nations building in Abuja that killed 24 people in August. It was their largest bomb attack and followed months of increasing violence centered on northeastern Nigeria.
There are reports that the group has forged alliances with terrorist groups in neighboring African countries, including an Al Qaeda affiliate operating in Mali, Al Qaeda in the Islamic Maghreb. Boko Haram itself has claimed ties with Al Shabaab Islamic militants in Somalia.
