Around February 1993: Three WTC Bombers Travel on Saudi Passports with Indicator of Islamist Extremism, Presumably Tracked by Saudi Authorities

The 9/11 Commission, relying on a CIA report, will later say that three of the men involved in the 1993 World Trade Center bombing travel on Saudi passports containing an indicator of possible Islamist extremism. [9/11 Commission, 8/21/2004, pp. 46-47, 61 ] Author James Bamford will say that it is a “secret coded indicator, placed there by the Saudi government, warning of a possible terrorist affiliation.” [Bamford, 2008, pp. 58-59] It is unclear what the indicator looks like precisely and who the men are. However, Ahmad Ajaj, an associate of lead bomber Ramzi Yousef, does have a Saudi passport. Some of the 9/11 hijackers will later use Saudi passports with the same indicator (see October 28, 2000, June 1, 2001, and June 13, 2001, and November 2, 2007).
