GUANTANAMO BAY, CUBA – MARCH 29: (EDITORS NOTE: Image has been reviewed by the U.S. Military prior to transmission.) A U.S. military prison guard watches over a detainee in the maximum security Camp 5 of the Guantanamo Bay detention center on March 29, 2010 in Guantanamo Bay, Cuba. U.S. President Barack Obama pledged to close the prison by early 2010 but the administration has struggled to transfer, try or release the remaining detainees from the facility, located at the U.S. Naval base on the Caribbean island.
