Men of the Nigerian armed Islamist group Boko Haram attacked Sunday six communities in northern Cameroon almost simultaneously, killing at least three civilians, said a source in the Ministry of Defense.

“Six attacks were carried out almost simultaneously Sunday” in six areas of the Cameroon region of the far north, on the border with Nigeria, the source said on condition of anonymity. Among these locations are Kolofata Fotokol and two Cameroonian cities where high voltage Boko Haram has stepped up attacks and kidnappings in recent months.

A Fotokol, near Lake Chad, “at least three civilians were killed” by Islamists. The overall balance of these attacks “is certainly heavy”, especially on the side of Boko Haram, “but remains indeterminate” for the moment, the source said.

“It was probably coordinated attacks, as Boko Haram had armored vehicles,” said the source, adding that the Cameroonian army had repelled the attackers in Nigeria.

“Our soldiers are at the front and spare no efforts (…) They sacrifice their lives to protect ours,” he has said, stressing that the Cameroonian army had inflicted “heavy losses” on Boko Haram in recent weeks. “We have no choice but to win the war and we will win,” said the minister.
