War on terror or war of error?
Only 5 per cent of Guantanamo detainees were actually captured by U.S. forces. The rest were turned over by Pakistani or Northern Alliance forces, in some cases in exchange for thousands of dollars.
Some 345 detainees have been transferred out to 26 different countries, including Australia, Belgium, Canada, Denmark, France, Germany, Spain, Sweden and the UK.
Hooding, stripping, sensory deprivation, isolation, stress positions and the use of dogs to "induce stress" are approved interrogation techniques at Guantanamo.
More than 200 Guantanamo detainees have gone on hunger strikes.
Some 40 have attempted suicide. When three detainees died in June, apparently as a result of suicide, the base commander said the detainees had killed themselves as "an act of asymmetric warfare." The deputy assistant secretary of state for public diplomacy dismissed the deaths as "a good PR move."
Amnesty International says Guantanamo is the hub of the CIA's unlawful rendition program and that officials from other countries, including China and Libya, have interrogated detainees there.
