Future 9/11 hijacker Khalid Almihdhar stays at al-Qaeda’s communications hub in Yemen again. His father-in-law Ahmed al-Hada runs the hub in Sana’a, Yemen, where Almihdhar’s wife and other family live. Almihdhar stayed at the hub for around a month in June 2000 (see (Mid-June-Mid-July 2000)) and then traveled around Asia until returning to it now. It is unclear how long he stays, except he goes to Afghanistan for an unknown amount of time and then is in the United Arab Emirates and Malaysia in June 2001. [9/11 Commission, 7/24/2004, pp. 237] He may travel to Afghanistan via Iran later in February (see February 2001). [9/11 Commission, 7/24/2004, pp. 241, 529; Shenon, 2008, pp. 370-3] He will fly from Sana’a to Saudi Arabia on May 26, 2001, and probably stays at the hub again while in Sana’a (see (May 26, 2001)). The CIA and NSA have been closely monitoring the hub for years. Phone calls to and from it, including ones made by Almihdhar and other 9/11 hijackers, are intercepted, rooms in the building are bugged, and spy satellites record visitors (see Late August 1998, Late 1998-Early 2002, and Early 2000-Summer 2001). Based on information gained from monitoring this house, the CIA and local intelligence services mounted a major operation against Almihdhar, other 9/11 hijackers, and several more al-Qaeda operatives in December 1999 and January 2000, when they were followed around the Middle East and South Asia and monitored during an al-Qaeda summit in Malaysia (see December 29, 1999, January 2-5, 2000, and January 5-8, 2000). So presumably US intelligence should be aware of this visit to the hub and who Almihdhar is, but what exactly is known and who may know it will not be made public.
