He became the victim of enforced disappearance in the USA's secret detention program which, like torture is a crime under international law.
Abu Zubaydah was transferred to Guantanamo in September 2006 where he and other former CIA detainees are held in Camp 7 where conditions are the most isolating. Since his transfer to Guantanamo, Abu Zubaydah is reported to have suffered more than 150 seizures. His medical health continues to be of serious concern.
He has never been charged, despite being accused for years by US authorities of involvement in serious crimes.
