Up to one million people may have fled their homes because of violence following Ivory Coast's disputed elections, the UN refugee agency says. The UNHCR says most had run away from recent violence in Abidjan. Aid agencies are said to be unable to reach parts of the west where forces loyal to disputed President Laurent Gbagbo have been losing ground. France has circulated a draft resolution at the UN calling for sanctions against Mr Gbagbo. This follows a calls for UN sanctions and tougher action to oust him by West African leaders. Fear of war Mr Gbagbo is resisting calls for him to cede power to his rival, Alassane Ouattara - widely recognised as the winner of last year's election in the world's largest cocoa producer. "The massive displacement in Abidjan and elsewhere is being fuelled by fears of all-out war," said UNHCR spokeswoman Melissa Fleming. She pointed out that the estimate of up to a million displaced was double the figure from just a week ago.
