The US justice department has agreed to transfer a Yemeni inmate from America's controversial Guantanamo Bay prison. But it declined to provide details of where Ayman Saeed Batarfi would go. The 38-year-old Yemeni doctor has been held at Guantanamo since 2002, a year after he was detained in Afghanistan on suspicion of assisting al-Qaeda. Some 250 detainees are being held at Guantanamo. In January, US President Barack Obama ordered the prison in Cuba to be closed within a year. Mr Obama also ordered a review of military trials for terror suspects and a ban on harsh interrogation methods.
