The Pentagon is considering sending military advisers to Nigeria to train local troops to fight Boko Haram insurgents and boost security in the violence-wracked nation, a US official said Friday.

The defense official, who spoke on condition of anonymity, said the US military made a string of recommendations after Nigeria’s leaders asked for help determining “possible courses of action” in the fight against the Islamist militants.

One recommendation was to send a group of US advisers—most likely special operations troops—to Nigeria to train local forces. They would not be in a combat role.

Such a mission would be a resumption of an earlier Pentagon effort that Nigeria stopped in late 2014 amid US concerns of suspected Nigerian army abuses and its failure to protect civilians.
