Some of the 180 high security prisoners walk in the exercise pitch at Camp Bucca on the outskirts of the southern city of Basra, 550 kms from Baghdad, on September 16, 2009. The US-run prison will close today with the remaining 180 prisoners being sent north to Camp Taji and Camp Cropper. At its peak in 2007, Camp Bucca held 22,000 prisoners. It will now be transfered to the Iraqi authorities and will be developed in a base for the Iraqi Marines. AFP PHOTO / ESSAM AL-SUDANI (Photo credit should read ESSAM -AL-SUDANI/AFP/Getty Images)
