The CIA and United Arab Emirates (UAE) officials apparently fail to warn German intelligence about future 9/11 hijacker Ziad Jarrah. On January 30, 2000, Jarrah was questioned at Dubai airport in the UAE, and the CIA was involved in a decision to not arrest him (see January 30-31, 2000). But even though Jarrah’s flight from Dubai was tracked to Hamburg, Germany, apparently neither US nor UAE officials warn German intelligence about Jarrah. During Jarrah’s brief detention he confessed that he had just come from Pakistan and Afghanistan, and he had a large number of jihadist propaganda videos in his luggage, leading UAE officials to strongly suspect he had just been to a militant training camp in Afghanistan. He also revealed that he has plans to learn how to fly airplanes in the US. An unnamed top German intelligence official will later say: “If we had been given the information that Jarrah had been to Afghanistan and was planning to go to flight school, we might have asked the Americans whether they thought this was normal.… If they had asked us, ‘Who is this guy who is learning to fly?’ then perhaps there might have been a different outcome.” He will suggest German intelligence might have started monitoring Jarrah, and thus discovered the 9/11 plot. However, this official will complain: “But it was one-way traffic [with the CIA]. You gave information, and you got no response.” The CIA will later deny that it has any knowledge of Jarrah before 9/11. [Vanity Fair, 11/2004] Note that a UAE official claims that the CIA said it would secretly track Jarrah from Dubai airport (see January 30-31, 2000). If this is true, it could explain why neither the UAE nor CIA told Germany about Jarrah.
