Boko Haram Islamists have killed 10 people, including two soldiers, and torched several homes during a raid in northern Cameroon.
A BIR officer also confirmed the toll.
The Islamists also burnt several houses in the town, which lies near Lake Chad, before retreating to Nigeria, the security source said.
Nigeria’s neighbours, Chad, Cameroon and Niger, which have all suffered attacks by Boko Haram, launched a regional force earlier this year to end a conflict that has claimed more than 15,000 lives since 2009.
Many of the insurgents are hiding out in Lake Chad, a shallow, marshy water body dotted with hundreds of islets, and in Nigeria’s Sambisa Forest near the border with Cameroon.
