The IMF says steady annual progress is needed starting now in reducing borrowing needs. Some countries have started, but the report notes that in the United States, the effort has been put on hold.

Contrary to earlier reports, the United Nations says the former President of Ivory Coast Laurent Gbagbo is still being held in the country's main city Abidjan.

Unusual scenes were playing out today at a once luxury hotel overlooking Abidjan lagoon. The president of Ivory Coast is staying in a hotel suite. Downstairs in a conference room, the top military brass of the country are jostling for positions in a new army. President Ouattara has to walk a political and military tightrope. On the one hand, he has to reward the men who were once called rebels, who helped him come to power. On the other hand, he can't sack or imprison all those who fought against him or he risks alienating too many men with guns.
