YAOUNDE, Shawwal 14, 1436, July 30, 2015, SPA -- The leaders of Nigeria and Cameroon pledged on Thursday to improve the exchange of intelligence and security cooperation along their border in a bid to tackle Nigerian militant group Boko Haram, Reuters reported. Concluding his first visit to Cameroon since he was elected in March, Nigerian President Muhammadu Buhari and his Cameroonian counterpart Paul Biya voiced support in a joint statement for a planned multinational task force to fight Boko Haram, which has sworn allegiance to ISIS. Buhari's visit came after the Nigerian militant group launched a wave of attacks in Nigeria, Cameroon, Chad and Niger that has killed hundreds of people in the past two months. The attacks follow a four-month military campaign by Nigeria, Chad and Niger that drove Boko Haram out of the towns of northeast Nigeria. "The two heads of state note with satisfaction the weakening of the operational capabilities of Boko Haram," read a joint statement in French. "They expressed their common determination to eradicate Boko Haram and in this respect agreed to intensify intelligence sharing between their security services." --SPA 14:29 LOCAL TIME 11:29 GMT www.spa.gov.sa/w
