Cameroon's army killed at least 41 Islamist militants as it fought off a wave of attacks along its border with Nigeria over the weekend in an escalation in the conflict, the government said.The coordinated assaults on five towns and villages showed a change in tactics by Nigerian Boko Haram fighters, who have focused on hit-and-run raids on individual settlements in the past, Information Minister Issa Tchiroma added.
Boko Haram's campaign to carve out an Islamist caliphate has spread from its stronghold in northeast Nigeria to neighboring Cameroon, raising fears for an already unstable region also threatened by Islamist militants in the Sahel.
Cameroon has sent thousands of soldiers to its Far North region to fight off the militants and said it launched air attacks on the movement for the first time on Sunday.
