YAOUNDE, Cameroon, Rabi'II 28, 1436, February 17, 2015, SPA -- Suspected Boko Haram extremists attacked a Cameroonian military base near the border with Nigeria, killing at least five soldiers, an army colonel said Tuesday. Col. Joseph Nouma told The Associated Press that hundreds of the militants escaped back to Nigeria on Monday after looting scores of homes in the area and setting fire to them. Eight wounded Cameroonian soldiers were brought to a military hospital in the capital, he said. The renewed cross-border violence came as heads of states from Central African countries were ending a meeting in the Cameroonian capital, Yaounde, to plan the creation of a joint military response to the growing regional threat posed by Boko Haram. The 10 member states announced that they had contributed more than 50 percent of the $100 million needed to fight Boko Haram. They also called on Nigeria to cooperate by allowing the multinational joint task force to attack Boko Haram in its strongholds in Nigeria. --SPA 13:24 LOCAL TIME 10:24 GMT www.spa.gov.sa/w
