Detainees pray at a U.S. military detention facility Camp Bucca, Iraq, Monday, March 16, 2009. The United States aims to shut down its largest detention center, Camp Bucca, by 2010. More than 9,600 detainees who were captured as national security threats over the last four years are still being held there; at its peak, the prison located 340 miles southeast of Baghdad held 26,000 detainees. Under the Jan. 1 security agreement with Iraq, the U.S. has released more than 1,8000 detainees so far this year and expect to release as many as 1,300 each month. (AP Photo/Dusan Vranic)
