Liberian rebel leader Charles Taylor signed a cease-fire with other warring factions, but observers at peace talks said groundwork had not been laid for a political solution to the civil war in Liberia.

Some sources at the Bamako summit of the Economic Community of West African States (ECOWAS) in Mali said Taylor was forced to sign the cease-fire Wednesday because of pressure from his main military backers, Libya and Burkina Faso.But Taylor denied that he had received backing from either country and said he had not been forced to sign the cease-fire agreement. "I have been the most generous in this, with 90 percent of the country and people under my control, giving up everything to bring peace to my people," he said.
