A guard opens the gate to Camp Delta at the Guantanamo Bay Naval Station in Guantanamo Bay, Cuba in this September 4, 2007 file photo. Ringed by cells where bearded men pace back and forth behind windowed doors, a U.S. sailor in camouflage fatigues stood by a metal table with a roll of toilet paper, portioning out strips of 30 squares each. The guard is among 1,800 U.S. troops at the camp that holds 340 suspected al Qaeda and Taliban captives at the U.S. naval base in southeast Cuba and their commander is worried about their morale.
