Late Summer 1999: NSA Intercepts Calls Mentioning 9/11 Hijacker Almihdhar, Does Not Disseminate Information

The NSA intercepts more calls involving an al-Qaeda communications hub in Sana’a, Yemen (see Early 1999 and Summer 1999). The names of Khaled, who turns out to be 9/11 hijacker Khalid Almihdhar, and others are mentioned in the calls. However, the NSA reportedly does not think the intelligence gleaned from the calls is important and does not disseminate it. [US Congress, 7/24/2003, pp. 156 ] However, the FBI regarded the hub as a key element in al-Qaeda’s communications network and after 9/11 a senior US counterterrorism official will say, “The NSA was well aware of how hot the number was… and how it was a logistical hub for al-Qaeda.” Several plots are stopped based on information obtained from listening to calls to and from the hub (see Late 1998-Early 2002).
