SANAA (AFP) - A government of unity will be announced in Yemen before Sunday, the opposition said, in line with a peace deal that is to see President Ali Abdullah Saleh step down from power. "There is a deal with the ruling party on the distribution of posts. Forming a cabinet will be very easy," Mohammed Qahtan, spokesman for the parliamentary opposition coalition, told AFP. The government will be announced on Friday or Saturday, he added. Opposition chief Mohammed Basindawa was charged on Sunday with forming a government tasked with overseeing a 90-day interim period until Saleh's agreed departure in February. The peace deal, agreed under the auspices of the Gulf Cooperation Council in Riyadh last week, is meant to end 10 months of crisis that has led to violent protests and intense street fighting across Yemen. In it, the opposition is to evenly share cabinet portfolios with Saleh's ruling party. On Thursday, more than 13 people were killed in clashes between forces loyal to Saleh and dissident tribesmen in the country's second-largest city Taez.
