Islamic Army of the Caucasus

Phoenix, Arizona, FBI agent Ken Williams sends a memorandum warning about suspicious activities involving a group of Middle Eastern men taking flight training lessons in Arizona. The memo is titled: “Zakaria Mustapha Soubra; IT-OTHER (Islamic Army of the Caucasus),” because it focuses on Zakaria Soubra, a Lebanese flight student in Prescott, Arizona, and his connection with a terror group in Chechnya that has ties to al-Qaeda. It is subtitled: “Osama bin Laden and Al-Muhjiroun supporters attending civil aviation universities/colleges in Arizona.” [Fortune, 5/22/2002; Arizona Republic, 7/24/2003] Williams’ memo is based on an investigation of Sorba that Williams had begun in 2000 (see April 2000), but he had trouble pursuing because of the low priority the Arizona FBI office gave terror investigations (see April 2000-June 2001). Additionally, Williams had been alerted to suspicions about radical militants and aircraft at least three other times (see October 1996; 1998; November 1999-August 2001). In the memo, Williams does the following:
Names nine other suspect students from Pakistan, India, Kenya, Algeria, the United Arab Emirates, and Saudi Arabia. [Die Zeit (Hamburg), 10/1/2002] Hijacker Hani Hanjour, attending flight school in Arizona in early 2001 and probably continuing into the summer of 2001 (see Summer 2001), is not one of the students, but, as explained below, it seems two of the students know him. [US Congress, 7/24/2003, pp. 135 ; Washington Post, 7/25/2003]
Notes that he interviewed some of these students, and heard some of them make hostile comments about the US. Additionally, he noticed that they were suspiciously well informed about security measures at US airports. [Die Zeit (Hamburg), 10/1/2002]
Notes an increasing, “inordinate number of individuals of investigative interest” taking flight lessons in Arizona. [Die Zeit (Hamburg), 10/1/2002; US Congress, 7/24/2003, pp. 135 ]
Suspects that some of the ten people he has investigated are connected to al-Qaeda. [US Congress, 7/24/2003, pp. 135 ] One person on the list, Ghassan al Sharbi, will be arrested in Pakistan in March 2002 with al-Qaeda leader Abu Zubaida (see March 28, 2002). Al Sharbi attended a flight school in Prescott, Arizona. He also apparently attended the training camps in Afghanistan and swore loyalty to bin Laden in the summer of 2001. He apparently knows Hani Hanjour in Arizona (see October 1996-Late April 1999). He also is the roommate of Soubra, the main target of the memo. [Los Angeles Times, 1/24/2003; 9/11 Commission, 7/24/2004, pp. 521]
Discovers that one of them was communicating through an intermediary with Abu Zubaida. This apparently is a reference to Hamed al Sulami, who had been telephoning a Saudi imam known to be Zubaida’s spiritual advisor. Al Sulami is an acquaintance of Hanjour in Arizona (see October 1996-Late April 1999). [Mercury News (San Jose), 5/23/2002; 9/11 Commission, 7/24/2004, pp. 520-521, 529]
Discusses connections between several of the students and a radical group called Al-Muhajiroun. [Mercury News (San Jose), 5/23/2002] This group supported bin Laden, and issued a fatwa, or call to arms, that included airports on a list of acceptable terror targets. [Associated Press, 5/22/2002] Soubra, the main focus of the memo, is a member of Al-Muhajiroun and an outspoken radical. He met with Sheikh Omar Bakri Mohammed, the leader of Al-Muhajiroun in Britain, and started an Arizona chapter of the organization. After 9/11, some US officials will suspect that Soubra has ties to al-Qaeda and other terrorist groups. He will be held two years, then deported to Lebanon in 2004. [Los Angeles Times, 10/28/2001; Los Angeles Times, 1/24/2003; Arizona Republic, 5/2/2004; Arizona Monthly, 11/2004] Though Williams doesn’t include it in his memo, in the summer of 1998, Bakri publicized a fax sent by bin Laden to him that listed al-Qaeda’s four objectives in fighting the US. The first objective was “bring down their airliners.”
(see Summer 1998). [Los Angeles Times, 10/28/2001]
Warns of a possible “effort by Osama bin Laden to send students to the US to attend civil aviation universities and colleges” [Fortune, 5/22/2002] , so they can later hijack aircraft. [Die Zeit (Hamburg), 10/1/2002]
Recommends that the “FBI should accumulate a listing of civil aviation universities and colleges around the country. FBI field offices with these types of schools in their area should establish appropriate liaison. FBI [headquarters] should discuss this matter with other elements of the US intelligence community and task the community for any information that supports Phoenix’s suspicions.” [Arizona Republic, 7/24/2003] (The FBI has already done this, but because of poor FBI communications, Williams is not aware of the report.)
Recommends that the FBI ask the State Department to provide visa data on flight school students from Middle Eastern countries, which will facilitate FBI tracking efforts. [New York Times, 5/4/2002]
The memo is addressed to the following FBI Agents:
Dave Frasca, chief of the Radical Fundamentalist Unit (RFU) at FBI headquarters;
Elizabeth Harvey Matson, Mark Connor and Fred Stremmel, Intelligence Operations Specialists in the RFU;
Rod Middleton, acting chief of the Usama bin Laden Unit (UBLU);
Jennifer Maitner, an Intelligence Operations Specialist in the UBLU;
Jack Cloonan, an agent on the New York FBI’s bin Laden unit, the I-49 squad; (see January 1996 and Spring 2000).
Michael S. Butsch, an agent on another New York FBI squad dealing with other Sunni terrorists. [Federal Bureau of Investigation, 7/10/2001 ; US Congress, 7/24/2003, pp. 135 ]
However, the memo is not uploaded into the FBI’s information system until the end of the month and is apparently not received by all these people (see July 27, 2001 and after). Williams also shares some concerns with the CIA (see (July 27, 2001)). [Mercury News (San Jose), 5/23/2002] One anonymous government official who has seen the memo says, “This was as actionable a memo as could have been written by anyone.” [Insight, 5/27/2002] However, the memo is merely marked “routine,” rather than “urgent.” It is generally ignored, not shared with other FBI offices, and the recommendations are not taken. One colleague in New York replies at the time that the memo is “speculative and not very significant.” [Die Zeit (Hamburg), 10/1/2002; US Congress, 7/24/2003, pp. 135 ] Williams is unaware of many FBI investigations and leads that could have given weight to his memo. Authorities later claim that Williams was only pursuing a hunch, but one familiar with classified information says, “This was not a vague hunch. He was doing a case on these guys.” [Mercury News (San Jose), 5/23/2002]
