Salem Alhazmi.Salem Alhazmi. [Source: FBI]As the NSA continues to monitor an al-Qaeda communications hub in Yemen run by hijacker Khalid Almihdhar’s father-in-law (see Late August 1998), they find references to Almihdhar and the hijacker brothers, Salem and Nawaf Alhazmi. They also learn that Almihdhar and Nawaf Alhazmi are long time friends. [9/11 Commission, 1/26/2004, pp. 6 pdf file; 9/11 Commission, 1/26/2004] In early 1999, the NSA intercepts communications mentioning the full name “Nawaf Alhazmi.” However, this information is not disseminated to the intelligence community, as it apparently does not meet NSA reporting thresholds. The 9/11 Congressional Inquiry will say, “Those thresholds vary, depending on the judgement of the NSA analyst who is reviewing the intercept and the subject, location, and content of the intercept.” Another intelligence organisation intercepts the same or similar calls and reports this to the NSA. The Inquiry comments: “NSA’s practice was to review such reports and disseminate those responsive to US intelligence requirements. For an undetermined reason, NSA did not disseminate the […] report.” [Associated Press, 9/25/2002; US Congress, 10/17/2002; US Congress, 7/24/2003, pp. 135 pdf file] The NSA continues to intercept such calls and finds more information a few months later (see Summer 1999 and Late Summer 1999). Near the end of 1999, there will be additional intercepts that give Khalid Almihdhar’s full name and the first names of the other two (see Shortly Before December 29, 1999). But while the NSA will provide some information about these new intercepts to the CIA and other agencies, they will not go back to the earlier intercepts to figure out Nawaf’s full name and close connection to Almihdhar (see December 29, 1999).

The National Security Agency (NSA) intercepts calls between 9/11 hijacker Khalid Almihdhar in the US and an al-Qaeda communications hub in Yemen, but does not notify the FBI that Almihdhar is in the US. However, the NSA disseminates reports about some of the calls, which are made from phones registered to Nawaf Alhazmi (see Spring-Summer 2000). The NSA will later say that it does not usually intercept calls between the US and other countries at this time, as it believes that this should be done by the FBI. Despite this, the NSA acquires information about such calls and provides the information to the FBI in regular reporting and in response to specific requests. The FBI, which has a standing request for such information about any calls between the communications hub in Yemen and the US (see Late 1998), then uses this information in its investigations based on warrants issued under the Foreign Intelligence Surveillance Act. The NSA will later tell the 9/11 Congressional Inquiry the reason the FBI is not notified about Almihdhar is because it does not realize that Almihdhar is in the US. However, no explanation is offered for why the NSA fails to realize this. [US Congress, 7/24/2003, pp. 36, 73-4 pdf file] This explanation will be contradicted by one offered in a 2004 article about the issue that reports the intercepts are not exploited precisely because the NSA knows one of the parties is in the US and therefore does not want to deal with his calls (see Summer 2002-Summer 2004 and March 15, 2004 and After). In addition, the FBI used information gained from intercepted calls to and from the hub in Yemen to make a world map of al-Qaeda’s organization, indicating that the locations talking to the hub could be determined by US intelligence (see Late 1998-Early 2002).

In the months after the USS Cole is bombed in autumn 2000 (see October 12, 2000), the NSA intercepts about half a dozen communications between hijacker Nawaf Alhazmi in the US and an al-Qaeda communications hub in Sana’a, Yemen, run by hijacker Khalid Almihdhar’s father in law, Ahmed al-Hada. [MSNBC, 7/21/2004; Los Angeles Times, 12/21/2005; US President, 12/26/2005 pdf file] The hub and people associated with it are thought to have played a support role in the Cole bombing (see also October 14-Late November, 2000 and October 4, 2001). [CNN, 2/14/2002; MSNBC, 7/21/2004] It was also involved in the bombing of US embassies in Tanzania and Kenya (see August 4-25, 1998). The NSA has been monitoring the number for at least two years (see Late August 1998) and the FBI has used it to map al-Qaeda’s global organisation (see Late 1998-Early 2002). The NSA had previously intercepted calls between hijacker Khalid Almihdhar in the US and the hub (see Spring-Summer 2000 and Early 2000-Summer 2001) and also intercepts a call between Alhazmi and the hub a few weeks before 9/11 (see (August 2001)).
