The American intelligence analysts who compiled the justifications for continuing to detain the captives taken in the "war on terror" made dozens of references to al Qaida safe houses, in Karachi, Pakistan.
Captives said to have been captured in a Karachi safe house include: Shawki Awad Balzuhair,[9] Ha Il Aziz Ahmed Al Maythali[10] Hassan Mohammed Ali Bin Attash, Sabri Mohammed Ebrahim Al Qurashi[11] Many of the captives in Guantanamo learned from the allegations they faced during their Combatant Status Review Tribunals or Administrative Review Board hearings that their continued detention was being justified because their name, or "known alias", was found on a suspicious list.
They alleged the safe houses had been used as an underground factory for the manufacture of the timers for time-bombs, and that five of the USS Cole bombers and seventeen of the nineteen hijackers in the September 11 attacks had stayed there.
Yosri Fouda, Al Jazeera's London bureau chief, interviewed Khalid Sheikh Mohammed in April 2002 in a Karachi safe house.
During this interview in the Karachi safe house Mohammed gave Fouda an unedited copy of the video of the beheading of American journalist Daniel Pearl.
