FILE - In this June 27, 2006 file photo, reviewed by a U.S. Department of Defense official, U.S. military guards walk within Camp Delta military-run prison, at the Guantanamo Bay U.S. Naval Base, Cuba. A senior U.S. official says the first of 17 detainees scheduled to be released from the Guantanamo Bay prison in January will be transferred next week, as the Obama administration continues efforts to reduce the population at the controversial detention center.
