On December 4, 1998, an item in President Clinton’s Presidential Daily Briefing (PDB) is titled, “Bin Laden Preparing to Hijack US Aircraft and Other Attacks.” The PDB says “Bin Laden and is allies are preparing for attacks in the US, including an aircraft hijacking to obtain the release of Sheikh Omar Abdul-Rahman, Ramzi Yousef, and Muhammad Sadiq ‘Awda. One source quoted a senior member of Al-Gama’a al-Islamiyya (IG) saying that, as of late October, the IG had completed planning for an operation in the US on behalf of bin Laden, but that the operation was on hold. A senior bin Laden operative from Saudi Arabia was to visit IG counterparts in the US soon thereafter to discuss options-perhaps including an aircraft hijacking.” The same source says bin Laden may implement plans to hijack US aircraft before the start of the Muslim holy month of Ramadan on December 20 and that two members of the operational team had evaded security checks in a recent trial run at a New York airport. A possible different source says that in late September, Mohammed Shawqui Islambouli, brother of the assassin of Egyptian President Anwar Sadat and described in the PDB as an IG leader, was planning to hijack a US airliner during the “next couple of weeks” to free Abdul-Rahman and other prisoners. The PDB also says that “some members of the bin Laden network have received hijack training, according to various sources, but no group directly tied to bin Laden’s al-Qaeda organization has ever carried out an aircraft hijacking. Bin Laden could be weighing other types of operations against US aircraft.” The PDB mentions other bin Laden related threats, including recent reports that the IG has obtained surface-to-air missiles and intends to move them from Yemen to Saudi Arabia to shoot down aircraft. [Washington Post, 7/18/2004; 9/11 Commission, 7/24/2004, pp. 128-130] The private intelligence group Stratfor will later say that, in addition to his ties with IG, Islambouli worked with bin Laden in the Maktab al-Khidamat charity front in Pakistan and is believed to have lived in Afghanistan in the 1990s as “part of the group of key Egyptian advisers surrounding bin Laden.” Islambouli will formally join with al-Qaeda in 2006. [Stratfor, 8/10/2006] In early 1998, the CIA ignored information from a recently retired CIA agent that claimed 9/11 mastermind Khalid Shaikh Mohammed was in a terrorist cell with Islambouli, both were experts on plane hijackings, and were planning to hijack planes (see Early 1998). Perhaps not coincidentally, on this same day, CIA Director George Tenet issues a “declaration of war” against al-Qaeda in a memo to the US intelligence community (see December 4, 1998). Also on this day, counterterrorism “tsar” Richard Clarke holds a meeting of his interagency Counterterrorism and Security Group (CSG) to discuss the threat. The group agrees that New York City airports should go on a maximum security alert that weekend and security should be boosted at other East Coast airports. The FBI, FAA, and New York City Police Department get versions of the PDB report. Later in December and again in January 1999 the source says the hijacking has been postponed because two operatives have been arrested in Washington or New York. But the FBI is unable to find any information to support the threat nor is it able to verify any arrests similar to what the source described, and the source remains mysterious. The high alert in New York airports is canceled by the end of January. [9/11 Commission, 7/24/2004, pp. 128-130] This PDB will be mentioned in President Bush’s famous August 6, 2001 PDB, but mentions that US officials “have not been able to corroborate” the plot (see August 6, 2001).
Late December 1998: Data Mining Program Authorized to Go after Bin Laden
Chairman of the Joint Chiefs of Staff General Henry Shelton will later say, “Right after I left SOCOM [Special Operations Command], I asked my successor to put together a small team, if he could, to try to use the Internet and start trying to see if there was any way that we could track down Osama bin Laden or where he was getting his money from or anything of that nature.” A team of six intelligence officers will be given this task and Shelton will be periodically briefed on the progress of the program. But apparently the team, later to be called Able Danger, will focus on data mining tasks relating to Bosnia and China for most of 1999. [Sacramento Bee, 12/7/2005; US Congress, 2/15/2006] General Peter Schoomaker, the head of SOCOM, helped come up with the idea for Able Danger and helps to set it up. SOCOM, based in Tampa, Florida, is responsible for America’s secret commando units. [Government Security News, 9/2005] Mark Zaid, a lawyer for several Able Danger whistleblowers in 2005, will give this description of Able Danger: “In the most understandable and simplistic terms, Able Danger involved the searching out and compiling of open source or other publicly available information regarding specific targets or tasks that were connected through associational links. No classified information was used. No government database systems were used.… The search and compilation efforts were primarily handled by defense contractors, who did not necessarily know they were working for Able Danger, and that information was then to be utilized by the military members of Able Danger for whatever appropriate purposes.” [US Congress, 9/21/2005] Representative Curt Weldon (R-PA) will say in 2005 that the military’s purpose for the Able Danger program was to enable it to “manipulate, degrade, or destroy the global al-Qaeda infrastructure.” [Washington Post, 8/13/2005] Apparently, Able Danger does not begin to use real data to fight al-Qaeda until near the end of 1999.
1999: Atta Said to Meet Los Angeles Airport Bomber in Spain
A Spanish newspaper later will claim that Ahmed Ressam, the al-Qaeda operative who attempted to bomb the Los Angeles airport at the turn of the millennium (see December 14, 1999), meets Mohamed Atta in the Alicante region of Spain in this year. It is unclear whether the men trained at the same camp while they were in Afghanistan. [Reuters, 11/26/2001; CTV, 9/14/2002] According to other Spanish reports, in 1997 or 1998 Atta was a student in Valencia under an assumed name (see 1997 or 1998). Valenica is less than 100 miles from Alicante. After his arrest, Ressam began cooperating with US investigators in the summer of 2001 (see May 30, 2001), leading to the possibility that he could have confirmed Atta’s identity as an al-Qaeda operative before 9/11, if he had been asked.
1999: CIA Launches Operation to Track Militants Passing through Dubai Airport
The CIA begins an operation to track or question suspected al-Qaeda operatives as they transit the airport in Dubai, United Arab Emirates (UAE). When it is revealed in 2002 that 9/11 hijacker Ziad Jarrah was questioned in January 2000 as a part of this operation (see January 30-31, 2000), sources from the UAE and Europe describe the operation to CNN, and one of them draws a map of the airport, showing how the operation usually worked and how the people wanted for questioning were intercepted. UAE officials are often told in advance of who is coming in and who should be questioned. Jarrah may be stopped because he is on a US watch list (see January 30, 2000). [CNN, 8/1/2002] In 2011, Dubai airport will be considered one of the top five busiest in the world in terms of international passengers. [Airports Council International, 4/30/2011] In the summer of 1999, the CIA also asks immigration officials throughout the Middle East to stop and question anyone who may be returning from militant training camps in Afghanistan (see Summer 1999).
9/11 Hijackers Pass through the Airport – Almost all the 9/11 hijackers pass through Dubai at some point in the months before 9/11, some repeatedly (see December 8, 2000, April 11-June 28, 2001, and June 2001). One of them, Khalid Almihdhar, has his passport photocopied in Dubai by local authorities and the CIA (see January 2-5, 2000). Also, three of the hijackers, Satam al Suqami, Ahmed Alghamdi, and Hamza Alghamdi, are the subject a US customs investigation at the time they pass through Dubai (see September 2000 and Spring 2001), but it is unknown if there is any attempt to track them through Dubai.
1999: British Intelligence Warns Al-Qaeda Plans to Use Aircraft, Possibly as Flying Bombs
MI6, the British intelligence agency, gives a secret report to liaison staff at the US embassy in London. The reports states that al-Qaeda has plans to use “commercial aircraft” in “unconventional ways,”
“possibly as flying bombs.” [Sunday Times (London), 6/9/2002]
1999: 9/11 Hijacker Atta Warns Religious Associate to Stay Away from Islamic Extremists
This year, future 9/11 hijacker Mohamed Atta is regularly attending Islamic study group meetings led by a fellow Hamburg student named Mohammed bin Nasser Belfas. By this time, Atta and most of the rest of the group have replaced their Western jeans and clean-shaven faces with long beards and tunics. After one of these meetings, Atta asks to privately see Volker Harum Bruhn, an ethnic German who is also a member of the group. Bruhn says that Atta strongly warns him to stay away from Islamic extremists, to follow the Koran strictly, and live a careful life. [Los Angeles Times, 9/1/2002; Knight Ridder, 9/9/2002]
1999: FBI Learns of Militant Group’s Plans to Send Students to US for Aviation Training; Investigation Opportunity Bungled
The FBI receives reports that a militant organization is planning to send students to the US for aviation training. The organization’s name remains classified, but apparently it is a different organization than one mentioned in a very similar warning the year before (see After May 15, 1998). The purpose of this training is unknown, but the organization viewed the plan as “particularly important” and it approved open-ended funding for it. The Counterterrorism Section at FBI headquarters issues a notice instructing 24 field offices to pay close attention to Islamic students from the target country engaged in aviation training. Ken Williams’s squad at the Phoenix FBI office receives this notice, although Williams does not recall reading it. Williams will later write his “Phoenix memo” on this very topic in July 2001 (see July 10, 2001). The 9/11 Congressional Inquiry later will conclude, “There is no indication that field offices conducted any investigation after receiving the communication.” [US Congress, 7/24/2003] However, an analyst at FBI headquarters conducts a study and determines that each year there are about 600 Middle Eastern students attending the slightly over 1,000 US flight schools. [New York Times, 5/4/2002; US Congress, 7/24/2003] In November 2000, a notice will be issued to the field offices, stating that it has uncovered no indication that the militant group is recruiting students. Apparently, Williams will not see this notice either. [US Congress, 7/24/2003]
1999: FBI Headquarters Delays Check on Terrorist Trainer for 9 Months, Tries to Block Warning for National Guard
FBI Minneapolis agent Harry Samit learns that an unnamed man plans to travel from the US to Afghanistan to train militants there, and that one of his relatives has applied to join the Minnesota National Guard. Samit wants to run a check on him and notify the National Guard, as he is worried because guardsmen have access to local airports. However, he is blocked for several months by Michael Maltbie, an agent in the Radical Fundamentalist Unit at FBI headquarters, who becomes “extremely agitated” and says this is “just the sort of thing that would get the FBI into trouble.” [Star-Tribune (Minneapolis), 3/21/2006; Knight Ridder, 3/21/2006; Hearst Newspapers, 3/21/2006] Samit and Maltbie will later have another running disagreement over the Zacarias Moussaoui case (see August 15-September 10, 2001, August 20-September 11, 2001, August 27, 2001, and August 28, 2001).
1999: KSM Repeatedly Visits 9/11 Hijacker Atta and Others in Al-Qaeda’s Hamburg Cell
9/11 mastermind Khalid Shaikh Mohammed (KSM) “repeatedly” visits 9/11 hijacker Mohamed Atta and others in the Hamburg al-Qaeda cell. [Associated Press, 8/24/2002] US and German officials say a number of sources place KSM at Atta’s Hamburg apartment, although when he visits, or who he visits while he is there, is unclear. [Los Angeles Times, 6/6/2002; New York Times, 11/4/2002] However, it would be logical to conclude that he visits Atta’s housemate Ramzi Bin al-Shibh, since investigators believe he is the “key contact between the pilots” and KSM. [Los Angeles Times, 1/27/2003] KSM is living elsewhere in Germany at the time. [New York Times, 9/22/2002] German intelligence monitors the apartment in 1999 but apparently does not notice KSM. US investigators have been searching for Mohammed since 1996, but apparently never tell the Germans what they know about him. [New York Times, 11/4/2002] Even after 9/11, German investigators will complain that US investigators do not tell them what they know about KSM living in Germany until they read it in the newspapers in June 2002. [New York Times, 6/11/2002]
1999: Germans Miss Links between Hamburg 9/11 Hijackers and Key Al-Qaeda Operative
The 9/11 Commission will later call Mohamedou Ould Slahi “a significant al-Qaeda operative who, even [in late 1999], was well known to US and German intelligence, though neither government apparently knew he was operating in Germany.” [9/11 Commission, 7/24/2004, pp. 165]
Thinks He Was Monitored – However, while in US custody after 9/11, Slahi will allege that a phone call he received in January 1999 from his cousin Mahfouz Walad Al-Walid, a top al-Qaeda leader living in Afghanistan, was monitored. Slahi will say, “I later learned that my cousin was using Osama bin Laden’s satellite phone that was intercepted.” Another mutual cousin was arrested that month and Slahi says, “I wasn’t captured, but I am sure I was followed by the German police [and/or] German intelligence.” He claims the imam at his mosque told him that German officials had come to ask questions about him and was told Slahi had ties with terrorists. [US Department of Defense, 4/20/2006, pp. 184-216] In 2000, the New York Times will report that German authorities became interested in Slahi “shortly after the bombings of American Embassies in East Africa in 1998. The German authorities learned that [he] might have ties to Islamic extremists in Europe.” [New York Times, 1/29/2000]
Links to 9/11 Hijackers – After Hamburg al-Qaeda cell member Ramzi bin al-Shibh is captured in 2002, he will allegedly claim that Slahi was the one who originally recruited 9/11 hijackers Marwan Alshehhi and Ziad Jarrah. [Agence France-Presse, 10/26/2002] After 9/11, another prisoner in US custody will say that Slahi and bin al-Shibh met in Frankfurt in 1999 through an acquaintance. This acquaintance will go further and will claim Slahi knew bin al-Shibh and Jarrah since at least 1998 and that Slahi later lived with them in Hamburg. [9/11 Commission, 7/24/2004, pp. 496] In October 1999, bin al-Shibh and Alshehhi call Slahi, and he invites them to come to where he lives in Duisburg, Germany. Bin al-Shibh, Alshehhi, and Ziad Jarrah soon go visit him there. Karim Mehdi, an apparent leader of the al-Qaeda Ruhr Valley cell who will later be sentenced to nine years in prison for a post-9/11 plot, is also at this meeting. Bin al-Shibh, Alsehhi, and Jarrah follow Slahi’s advice to go to Afghanistan instead of Chechnya, and he gives them instructions on how to meet up with al-Qaeda operatives there. [9/11 Commission, 7/24/2004, pp. 165; Deutsche Presse-Agentur (Hamburg), 8/3/2005; Associated Press, 10/26/2006] US investigators later believe Slahi worked closely on al-Qaeda matters with bin al-Shibh and instructed another militant to go to the US and to take part in the 9/11 plot. Additionally, he is believed to have a key role in Ahmed Ressam’s millennium plot (see December 15-31, 1999). [Los Angeles Times, 4/24/2006]
No Action – German authorities are monitoring and wiretapping the phones at bin al-Shibh’s apartment throughout 1999 (see November 1, 1998-February 2001 and 2000), but they apparently do not connect Slahi to the Hamburg militants or do not act on that connection. The Germans will apparently miss another chance to learn of his ties to the Hamburg cell in April 2000, when Slahi is arrested for three weeks in Germany and then let go (see January-April 2000). [US Department of Defense, 4/20/2006, pp. 184-216] Note that the testimonies of detainees such as Slahi and bin al-Shibh are suspect due to widespread allegations that they were tortured into confessions (for instance, see September 27, 2001).
