Yemen's opposition dismissed Monday a government plan for talks aimed at easing unrest after months of mass protests demanding President Ali Abdullah Saleh's overthrow, saying it had not even heard of any such “roadmap” for peace. Vice President Abd-Rabbu Hadi Mansour, who is acting president while Saleh remains in a Saudi Arabian hospital after an assassination attempt, said Sunday that a road map would be launched within a week. Government spokesman Tareq Al-Shami told Reuters the plan would centre on talks with the opposition. “The roadmap is based on all sides gathering at the dialogue table and discussing all the issues,” he said. But the opposition repeated its refusal to talk to the government until Saleh signs a transition plan brokered by Gulf Arab states which the 69-year-old president has backed out of signing three times. “We knew nothing about the idea of a road map. There is no such thing, and we have decided not to enter any dialogue until the Gulf initiative is signed or power is transferred to the vice president,” said Mohammed Basindwa, a leader in Yemen's political opposition coalition. Saleh is trying to cling to power after 33 years in office despite a bomb attack in June that severely wounded him and forced him to seek treatment in Riyadh. He has frustrated opposition hopes that he would concede defeat, instead vowing to return to Yemen and lead a national dialogue.
