Fewer than 20 percent of Guantánamo inmates have been members of al-Qaeda, a National Journal study suggested. The same survey concluded that a high percentage, perhaps the majority, of inmates were not captured on any battlefield, but were handed over by Afghan warlords or Pakistanis in return for rewards. Of the nearly 800 detainees who have reportedly been housed at Guantánamo since January 2002, approximately 445 have been released or transferred.
