Akhir 27, 1432 / April 1, 2011, SPA -- Heavy weapons fire erupted near Laurent Gbagbo's presidential palace in the centre of Abidjan on Friday, Reuters witnesses said. A military source close to the Gbagbo camp said that forces loyal to rival Alassane Ouattara were attacking the palace but Gbagbo's elite Republican Guard and militiamen were fighting back. Heavy weapons fire was also heard coming from Treichville, a neighbourhood where the Republican Guard has a base that is used to protect the bridges leading into central Abidjan.
