New Nigerian general to head multinational Boko Haram fight

Thursday's appointment comes as the West African nation's new president promised deeper collaboration with neighboring states in the fight against Islamic extremism.

President Muhammadu Buhari headed home Thursday after two days of talks in Yaounde, Cameroon, focused on Boko Haram.

Its attacks have spread across Nigeria's borders and forced tens of thousands of refugees to flee to neighboring states.
