9/11 hijacker Ahmed Alhaznawi departs Saudi Arabia, traveling to the United Arab Emirates (UAE). [Federal Bureau of Investigation, 10/2001, pp. 151 ] According to the 9/11 Commission, Alhaznawi may have had a passport with an indicator of Islamic extremism (see Before November 12, 2000). Such indicators were used by the Saudi authorities to track some of the hijackers before 9/11 (see November 2, 2007), so the Saudis may register his departure.
