Boko Haram insurgents from Nigeria today attacked a Cameroon military camp near the town of Waza in the north of the country, wounding several soldiers, reports Reuters, quoting an army spokesman.

Chad, Niger and Cameroon have begun a joint offensive against Boko Haram militants who have killed thousands of people in a bid to carve out an Islamist emirate in northern Nigeria, and have increasingly staged raids across nearby borders.

“The wounded are being evacuated. The insurgents have been stopped. An APC (armoured personnel carrier) was taken from them and several of them were killed,” Reuters quoted a Cameroonian military officer as telling journalists in Maroua, adding that the incident was continuing.

Earlier this month, Boko Haram fighters killed more than 100 people in the northern Cameroon town of Fotokol, including residents inside their homes and a mosque, a local political leader said.
