Islamist fighters from Nigeria’s Boko Haram group have stolen a large number of livestock in a village in Northern Cameroon. Simultaneously, in the process of carrying out their heist, they also killed at least 10 civilians.

“Boko Haram attacked the village of Bia overnight” Thursday to Friday, one source said, on condition of anonymity. “The toll is 10 civilians killed and a large number of livestock stolen.”

A source within the administration said there had been “a dozen deaths” in the raid.

Bia, in the Far North region, which borders Lake Chad, has been identified previously by security forces as a recruiting ground for Boko Haram militants.

The Nigerian-based Islamists also attacked a Cameroon army position in Amchide, on the border with Nigeria. “They burned houses in Amchide, but without losses on our side. The attack was repulsed. We don’t know yet about casualties on the enemy side,” the security source said.

Cameroon is taking part in a four-country offensive against Boko Haram, together with Chad, Niger and Nigeria.
