Three African presidents visiting Ivory Coast have failed to broker a deal over a new prime minister, Nigerian President Olusegun Obasanjo has said. Mr Obasanjo and the leaders of South Africa and Niger had hoped to choose a prime minister acceptable to President Laurent Gbagbo and Ivorian rebels. But Mr Obasanjo said he did not view the mission as a failure, adding that talks would resume within 10 days.
