YAOUNDE (Reuters) - Two female suicide bombers, suspected of belonging to Islamist militant group Boko Haram, killed three Nigerians in a truck full of refugees in a town in Cameroon's Far North region, a local government source said.
Military sources had said earlier that they suspected the bombers' target was a nearby mosque in Fotokol.
The first bomb went off during a security check and it was unclear if the second bomber had detonated her bomb or whether she had been killed first by Cameroonian forces.
Boko Haram wants to establish an Islamist state in northeastern Nigeria and has waged a six-year campaign of violence to that end, killing thousands of people and displacing two million others.
Neighboring countries, including Cameroon, joined forces against the group last year, as its offensive spread beyond Nigeria's borders.
