Early 2000-September 10, 2001: 9/11 Hijackers Have Several Links to Sheikh Omar Abdul-Rahman

The 9/11 hijackers have links to several people associated with “Blind Sheikh” Omar Abdul-Rahman, the spiritual head of the group that bombed the World Trade Center in 1993. Abdul-Rahman has been in prison since the mid-1990s.
9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi attend a mosque in San Diego that is visited by an unnamed associate of Abdul-Rahman who is under investigation by the Los Angeles FBI (see June 1999-March 2000);
The mosque is also attended by Osama Basnan, who threw a party for Abdul-Rahman in 1992 (see Spring 2000);
9/11 hijacker Mohamed Atta is seen with Adnan Shukrijumah, son of Abdul-Rahman’s former translator (see May 2, 2001) and Atta and hijacker Marwan Alshehhi may attend a mosque run by his father (see 2000-2001);
Hijacker Mohand Alshehri is seen near the Minnesota clinic where Abdul-Rahman is being held (see August 2001);
Some hijackers have the same mailing address as Abdul-Rahman and at least one of his associates (see Before September 11, 2001);
Khalid Almihdhar and other hijackers obtain false ID cards from Mohamed el-Atriss, an associate of an unindicted co-conspirator at Abdul-Rahman’s trial (see (July-August 2001)); [Lance, 2006, pp. 373]
In addition, people attending a Bronx mosque are warned to stay away from lower Manhattan on 9/11 (see Early September 2001).
In early 2000, the Able Danger data-mining program apparently identifies Atta, Alshehhi, Alhazmi, and Almihdhar as members of al-Qaeda through their associations with people linked to Abdul-Rahman (see January-February 2000).
