Spring-Summer 2000: Calls between 9/11 Hijacker in San Diego and Al-Qaeda Communications Hub Intercepted by NSA

Around eight calls made by hijacker Khalid Almihdhar from San Diego to an al-Qaeda communications hub in Sana’a, Yemen, run by his father-in-law Ahmed al-Hada are intercepted by the NSA. [US Congress, 7/24/2003, pp. xii, 16-17, 157 ; Los Angeles Times, 12/21/2005; Wright, 2006, pp. 343; New Yorker, 7/10/2006 ] At least one of the calls is made from a phone registered to hijacker Nawaf Alhazmi in their San Diego apartment. [US Department of Justice, 11/2004, pp. 251 ] Other calls are made from a mobile phone registered to Alhazmi. [McDermott, 2005, pp. 296] Calls may also be made from the communications hub to the US. [MSNBC, 7/21/2004]
Dates of Calls – One of the calls takes place days after they move into their San Diego apartment in February (see January 15-February 2000). [MSNBC, 7/21/2004] Another is on March 20, 2000 and lasts 16 minutes. [Federal Bureau of Investigation, 10/2001, pp. 57 ; US Department of Justice, 11/2004, pp. 251 ]
Intercepted by NSA – Although NSA analysts pick up Almihdhar’s first name, “Khalid,” they do not connect it to his second name, even though the NSA has been intercepting communications to and from the hub involving him throughout 1999 (see Early 1999 and December 29, 1999) and he is on the NSA watch list at this point (see Mid-January 2000). [US Congress, 7/24/2003, pp. xii, 16, 157 ; US News and World Report, 3/15/2004] Some, or perhaps all, of these calls are between Almihdhar and his wife, who lives at the communications hub and reportedly gives birth to a daughter in early 2000 while Almihdhar is in the US. [9/11 Commission, 7/24/2004, pp. 222; Suskind, 2006, pp. 94; Wright, 2006, pp. 343; New Yorker, 7/10/2006 ] However, the NSA analysts suspect that Khalid is part of an “operational cadre.” [US News and World Report, 3/15/2004]
Dissemination and Content – According to the 9/11 Congressional Inquiry, the NSA disseminates some of this information to the FBI, CIA, and other agencies, but not all of it, as it apparently does not meet reporting thresholds. It is unclear why it does not meet such thresholds, although some sources will suggest Almihdhar was just talking to his wife. [US Congress, 7/24/2003, pp. 157 ; US News and World Report, 3/15/2004; 9/11 Commission, 7/24/2004, pp. 222; Suskind, 2006, pp. 94] Another source suggests operational information was passed on during the calls (see Early 2000-Summer 2001). However, two FBI agents who worked on al-Qaeda cases relating to Yemen, Dan Coleman and Ali Soufan, will later claim that they and other senior counterterrorism officials only learn about these calls after 9/11. [Los Angeles Times, 12/21/2005; Suskind, 2006, pp. 94; New Yorker, 7/10/2006 ]
Significance – Author Lawrence Wright will comment: “You know, this is the key. The NSA is all over this phone. And everybody, you know, that has any connection with it is drawing links from that phone. Now imagine eight lines from Yemen to San Diego. How obvious would it be that al-Qaeda is in America[?]” [Federal News Service, 10/5/2006]
Other Calls – The NSA also intercepts various other communications between the hijackers and the communications hub (see Early 2000-Summer 2001).
