Marie said. A spokesman for Gbagbo later appealed for calm on state television and urged people not to attack foreigners pending an investigation into the bombing. Some 4,000 French soldiers and more than 6,000 U.N. troops are in Ivory Coast policing a buffer zone around a ceasefire line that cuts a swathe across the country and separates the rebels in the north from the government-run south. U.N. peacekeepers stopped two army convoys trying to cross into the zone on Friday, but rebel leaders have accused the peacekeepers of not doing more to stop government attacks. Rebel officials said government troops had moved into the confidence zone and were at Sakasso, a town 40 km (25 miles) south of the main rebel base of Bouake. Ivorian military sources said their forces were only 10 km (6 miles) from Bouake. --More 0048 Local Time 2148 GMT
