CAMEROON-FRANCE-NIGERIA-CHAD-HOSTAGES

TO GO WITH AFP STORY BY PATRICK FORT -- Cameroon Marine captain Aboubakar (front of boat) arrives in Blangoua, near Lake Chad on March 1, 2013. More and more security forces say it is probable that Nigerian Islamist extremist group Boko Haram, who claimed responsibility for the kidnapping of a French family on February 19 in northern Cameroon, have moved north towards Chad. "What I want, its to catch the bastards" Marine captain and head of the Cameroonian Marine presence on Lake Chad Aboubakar said. Lake Chad, a huge area with small islands and canals separating it from Cameroon, Nigeria, Chad and Niger, is a possible hiding place for the kidnappers of the French family and their hostages.
