Zubaydah was captured in Pakistan in March 2002 and has been in United States custody ever since, including four-and-a-half years in the secret prison network of the Central Intelligence Agency (CIA). He was transferred among prisons in various countries including a year in Poland, as part of a United States' extraordinary rendition program. During his time in CIA custody, Zubaydah was extensively interrogated; he was water-boarded 83 times and subjected to numerous other torture techniques including forced nudity, sleep deprivation, confinement in small dark boxes, deprivation of solid food, stress positions, and physical assaults. Videotapes of some of Zubaydah's interrogations are amongst those destroyed by the CIA in 2005.
