July 24 or 28, 2001: Captured Operative Had Links That Could Have Led to Moussaoui, 9/11 Plot

High-level al-Qaeda operative Djamel Beghal is arrested in Dubai on his way back from Afghanistan. Earlier in the month the CIA sent friendly intelligence agencies a list of al-Qaeda agents they wanted to be immediately apprehended, and Beghal was on the list (see July 3, 2001).
Information Obtained – Beghal quickly starts to talk, and tells French investigators about a plot to attack the American embassy in Paris. Crucially, he provides new details about the international-operations role of top al-Qaeda deputy Abu Zubaida, whom he had been with a short time before. [New York Times, 12/28/2001; Time, 8/12/2002] One European official says Beghal talks about “very important figures in the al-Qaeda structure, right up to bin Laden’s inner circle. [He] mention[s] names, responsibilities and functions—people we weren’t even aware of before. This is important stuff.” [Time, 11/12/2001] One French official says of Beghal’s interrogations, “We shared everything we knew with the Americans.” [Time, 5/19/2002]
Link to 9/11 – The New York Times later will report, “Enough time and work could have led investigators from Mr. Beghal to an address in Hamburg where Mohamed Atta and his cohorts had developed and planned the Sept. 11 attacks.” Beghal had frequently associated with Zacarias Moussaoui. However, although Moussaoui is arrested (see August 16, 2001) around the same time that Beghal is revealing the names and details of all his fellow operatives, Beghal is apparently not asked about Moussaoui.

Timing of Arrest – Most media accounts place the arrest on July 28. However, in a 2007 book CIA Director George Tenet will say he received a briefing about the arrest on July 24. [Tenet, 2007, pp. 156-157]
