President Barack Obama is talking directly with the president of Yemen about what to do with almost 100 Yemeni nationals detained at Guantanamo Bay, hoping to ease the way for a mass transfer of prisoners from the soon-to-be-closed US prison. A senior administration official says Obama and President Ali Abdullah Saleh spoke for 25 minutes on Thursday. It was the first direct discussion between the two leaders about the future of terror suspects. The official described the call on condition of anonymity because of the sensitive negotiations. US officials are working on a deal that would send some or all the Yemeni detainees to Saudi Arabia. Saleh has said he wants his citizens returned to their own country.
