Nigerian President Olusegun Obasanjo arrived Friday in Ivory Coast on a mission to help resolve this war-divided West African nation's latest crisis. Obasanjo, who did not talk to reporters on arrival, was due to meet Ivory Coast President Laurent Gbagbo and other top officials in Abidjan before traveling to the northern city of Bouake for talks with rebel leader Guillaume Soro, the presidency said in a statement. On Monday, Gbagbo began a U.N.-backed extended year in office that has been fiercely opposed by opposition leaders and rebels who control the northern half of the country, according to a report of The Associated Press.
