ABIDJAN (AFP) - Tension mounted between Ivory Coast strongman Laurent Gbagbo and the international community on Monday, as the United Nations complained of rights abuses and the European Union slapped sanctions on him. Gbagbo has rejected demands he cede power to his rival Alassane Ouattara, and has instead ordered UN peacekeepers to leave the country, stirring fears the fragile West African state might plunge back into chaos. The United Nations has refused Gbagbos order to withdraw its 10,000-strong UNOCI force, and its chief human rights official accused Gbagbos security forces of involvement in dozens of alleged kidnappings and murders. The European Union decided Monday to slap visa bans on Gbagbo and 18 of his inner circle, diplomats said.
