Nigerian President Goodluck Jonathan said the delegation of West African leaders will return to Ivory Coast on Monday next for more negotiations to end the impasse over last month's disputed elections. Mr. Jonathan said, the decision was taken following a briefing from the delegation.The announcement came a day after they failed to persuade incumbent President Laurent Gbagbo to stand down. The Presidents of Benin, Sierra Leone and Cape Verde had travelled to the main city, Abidjan, as representatives of Ecowas. They had hoped Mr. Gbagbo would agree to cede power to Alassane Ouattara, widely considered to be the true winner.The regional body Ecowas has threatened to use force if he refuses to go. State-controlled TV has indicated that several million African nationals from other countries living in Ivory Coast might be at risk if threats from African countries of military intervention against Mr. Gbagbo continue.
