After the FBI and CIA obtain a passport photo of al-Qaeda leader Khallad bin Attash (see November 22-December 16, 2000), they are unable to connect him to one of his aliases, Salah Saeed Mohammed bin Yousaf, even though he had submitted an application for a US visa using this alias the year before (see April 3, 1999). Presumably, a search of visa applications would have turned up a photograph similar to the one the US now has of him, allowing the US to connect bin Attash to the alias. However, no such search is made, even though the CIA knows the alias is connected to 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar (see January 8, 2000), who obtained US visas at the same time bin Attash’s application was denied (see April 3-7, 1999). No such search is made even after the CIA connects bin Attash to Alhazmi and Almihdhar under bin Attash’s real name as well in early 2001 (see January 4, 2001). [9/11 Commission, 7/24/2004, pp. 192-3, 538; US Department of Justice, 11/2004, pp. 248, 267-278 ] The US misses other opportunities to learn more about this alias (see After January 8, 2000 and After August 23, 2001).
