Forces opposed to Ivory Coast leader Laurent Gbagbo have launched a final assault on the presidential residence where he is holed up. Mr Gbagbo has been in negotiations with the UN over the terms of his departure, after being besieged by troops loyal to his rival Alassane Ouattara. A French government source said gunfire had erupted at Mr Gbagbo's residence in Abidjan. Mr Gbagbo and his family are believed to be sheltering in the bunker of the presidential residence, which was controlled by his troops. The spokesman of Mr Ouattara's prime minister, Guillaume Soro said, two days of heavy fighting stopped late Tuesday night and negotiations with Mr Gbagbo carried on throughout the night. But by Wednesday morning it appeared the patience of pro-Ouattara forces had run out and they are going to get Laurent Gbagbo out of his hole and hand him over to the president of the Republic. Mr Gbagbo insists he won last November's run-off vote. But the Ivorian election commission found that Mr Ouattara was the winner – a result certified by the UN.
