November/December 1999: Almihdhar Returns to Yemen, Falls under US Surveillance

9/11 hijacker Khalid Almihdhar returns from Afghanistan to Yemen, where he and his family live at an al-Qaeda communications hub that is being monitored by the US (see Late 1998-Early 2002). The NSA listens in on calls to his number and finds that he and several al-Qaeda leaders are to meet in Malaysia for a terrorism summit (see December 29, 1999). The reason for his departure to Yemen is unclear, as he has already been selected for the 9/11 operation and his fellow operatives are undergoing training in Afghanistan at this point (see Late 1999 and Early December 1999). Detainees give varying accounts of the reasons for his departure, as well as the exact timing. [9/11 Commission, 7/24/2004, pp. 157, 493] According to author James Bamford, Almihdhar returns to Yemen to be with his wife when he learns she is pregnant with their first child. [Bamford, 2008, pp. 11] Whatever the reason for Almihdhar’s travel to Yemen, while he is there al-Qaeda mounts an abortive attack against the USS The Sullivans (see January 3, 2000).
