Shortly Before December 29, 1999: NSA Monitors 9/11 Hijackers Talking to Each Other about Upcoming Al-Qaeda Summit

The NSA has been monitoring a telephone in an al-Qaeda communications hub in Yemen (see Late August 1998 and Late 1998-Early 2002). According to Vanity Fair, “Amid the storm of pre-millennial ‘chatter,’ the [NSA] intercepted communications among three Arabic men, each of whom bore some connection to the East Africa bombings (see 10:35-10:39 a.m., August 7, 1998) and to al-Qaeda.” The men are hijackers Khalid Almihdhar, Nawaf Alhazmi, and Salem Alhazmi. [Vanity Fair, 11/2004] Apparently, the NSA listens in on a phone call between al-Qaeda figure Khallad bin Attash and hijacker Khalid Almihdhar, who is staying at the hub. Attash mentions Almihdhar’s full name, as well as the first names of hijackers Nawaf Alhazmi and Salem Alhazmi. He says he wants the three of them to come to an important al-Qaeda summit in Malaysia in January 2000 (see January 5-8, 2000). The NSA has already heard the names of the three hijackers mentioned repeatedly in 1999 while monitoring the Yemen hub (see Early 1999). Apparently, US intelligence does not yet know bin Attash’s full name or role in al-Qaeda and won’t figure it out until late 2000 (see Early December 2000). [Wright, 2006, pp. 310] At the same time, US officials in Pakistan intercept Nawaf Alhazmi in Karachi calling Almihdhar at the Yemen hub. They learn Nawaf is planning a trip to Malaysia on January 4, 2000. The NSA is also monitoring Nawaf calling his brother Salem (the location of Salem at this time has not been revealed). [US Congress, 7/24/2003, pp. 143-144 ; Asia Times, 3/19/2004] The NSA will share details of these calls with the CIA and other agencies on December 29, 1999 (see December 29, 1999) and the CIA will eventually track Almihdhar to the Malaysia summit (see January 2-5, 2000).
