The CIA learns from the Jordanian government about an al-Qaeda millennium bombing plot in that country (see November 30, 1999). Further, the CIA concludes more attacks are likely soon, including some inside the US (see December 8, 1999). Counterterrorism “tsar” Richard Clarke is told of this, and he implements a plan to neutralize the threat. [Clarke, 2004, pp. 205, 211] The plan, approved by President Clinton, focuses on harassing and disrupting al-Qaeda members throughout the world. The FBI is put on heightened alert, counterterrorism teams are dispatched overseas, a formal ultimatum is given to the Taliban to keep al-Qaeda under control, and friendly intelligence agencies are asked to help. There are Cabinet-level meetings nearly every day dealing with terrorism [Washington Post, 4/2/2000; Associated Press, 6/28/2002] All US embassies, military bases, police departments, and other agencies are given a warning to be on the lookout for signs of an al-Qaeda millennium attack. One alert border agent responds by arresting terrorist Ahmed Ressam (see December 14, 1999), which leads to the unraveling of several bombing plots (see December 15-31, 1999). No terror attacks occur. However, Clarke claims the FBI generally remains unhelpful. For example, around this time the FBI says there are no websites in the US soliciting volunteers for training in Afghanistan or money for terrorist front groups. Clarke has a private citizen check to see if this is true, and within days, he is given a long list of such websites. The FBI and Justice Department apparently fail to do anything with the information. [Newsweek, 3/31/2004]
Late 1999: Hijacker Almihdhar Has Foreknowledge of Forthcoming Seaborne Attack
9/11 hijacker Khalid Almihdhar tells another operative that al-Qaeda is planning a ship-bombing attack. The US will learn this from a detainee interviewed in December 2001. The detainee will say that Almihdhar informed him that al-Qaeda operative Abd al-Rahim al-Nashiri was the plot’s originator. [9/11 Commission, 7/24/2004, pp. 491] Al-Nashiri discussed the ship bombing attack in a telephone call made in late 1998. The call may have been to the al-Qaeda communications hub at which Almihdhar lived and may also have been picked up by the US (see (Mid-August 1998)). Al-Qaeda soon attempts to attack the USS The Sullivans in Aden, Yemen, but the plan fails (see January 3, 2000). Almihdhar, who will be accused of participating in the plot to bomb the USS Cole in Yemen (see October 12, 2000, Early October 2001 and October 4, 2001), travels to Yemen shortly before the attack on the Sullivans (see November/December 1999) and apparently leaves one day after it (see January 2-5, 2000).
November/December 1999: Almihdhar Returns to Yemen, Falls under US Surveillance
9/11 hijacker Khalid Almihdhar returns from Afghanistan to Yemen, where he and his family live at an al-Qaeda communications hub that is being monitored by the US (see Late 1998-Early 2002). The NSA listens in on calls to his number and finds that he and several al-Qaeda leaders are to meet in Malaysia for a terrorism summit (see December 29, 1999). The reason for his departure to Yemen is unclear, as he has already been selected for the 9/11 operation and his fellow operatives are undergoing training in Afghanistan at this point (see Late 1999 and Early December 1999). Detainees give varying accounts of the reasons for his departure, as well as the exact timing. [9/11 Commission, 7/24/2004, pp. 157, 493] According to author James Bamford, Almihdhar returns to Yemen to be with his wife when he learns she is pregnant with their first child. [Bamford, 2008, pp. 11] Whatever the reason for Almihdhar’s travel to Yemen, while he is there al-Qaeda mounts an abortive attack against the USS The Sullivans (see January 3, 2000).
Late 1999: Counterterrorism ‘Tsar’ Clarke Holds Anti-Terrorist Training at the World Trade Center; 9/11-Style Attacks Not Envisaged
An anti-terrorist training session for the millennium celebration is held at the World Trade Center in New York. There are fears around this time that Osama bin Laden may want to launch attacks on the millennium, including within the US (see December 8, 1999). Representatives of 40 law enforcement and military agencies attend the meeting, which is chaired by counterterrorism “tsar” Richard Clarke. During two hours of brainstorming, no one envisages terrorists flying passenger planes into skyscrapers. New York City Deputy Mayor Rudy Washington is at the session, and will utilize what he learns on 9/11, so as to develop an emergency strategy in response to the attacks (see After 9:59 a.m. September 11, 2001). [New York Daily News, 5/20/2004]
December 9, 1999: President Clinton Warned about Al-Qaeda Operatives Living in US
As an al-Qaeda millennium plot is broken up in Jordan (see November 30, 1999), attention is focused on the fact that two of the plotters were long time US residents. National Security Adviser Sandy Berger sends a memo to President Clinton about the two men, Raed Hijazi and Khalil Deek. Hijazi had lived in California and then moved to Boston to drive a taxi there for several years. The 9/11 Commission will say Berger tells Clinton was a naturalized US citizen who had “been in touch with extremists in the United States as well as abroad.” Later in the month, counterterrorism “tsar” Richard Clarke will warn Berger in an e-mail, “Foreign terrorist sleeper cells are present in the US and attacks in the US are likely.” [9/11 Commission, 7/24/2004, pp. 179, 501] Deek is arrested on December 11 (see December 11, 1999), but he will eventually be released without being charged (see May 2001). A few days later, Clarke authorizes a study that looks into Deek’s connections, but no action will be taken when it is discovered Deek’s next-door neighbor is still living in Anaheim, California, and running an al-Qaeda sleeper cell there (see December 14-25, 1999). Similarly, while Hijazi will be arrested overseas some months later (see September 2000), US intelligence seems oblivious to the other al-Qaeda operatives who have been his roommates and fellow taxi drivers in Boston (see June 1995-Early 1999 and October 2000). One of them, Nabil al-Marabh, will apparently go on to have a major role in the 9/11 plot (see for example January 2001-Summer 2001 and Early September 2001). Investigators will also fail to act on knowledge of financial transactions between Hijazi and three of the 9/11 hijackers (see Spring 2001).
December 11, 1999: US Citizen, Alleged Mastermind of Jordanian Bomb Plot, Is Arrested but Never Charged
Khalil Deek is arrested by police in Peshawar, Pakistan, and immediately extradited to Jordan. The Jordanian government requested the arrest after tying Deek to a millennium plot to blow up hotels in Jordan that had been broken up a few days ago (see November 30, 1999). [Orange County Weekly, 6/15/2006] Deek is a naturalized US citizen who has been part of a California al-Qaeda sleeper cell for most of the 1990s. He had been investigated by US authorities since the late 1980s (see Late 1980s, March 1993-1996, and December 14-25, 1999) but was never arrested. Deek’s computer is confiscated when he is arrested, and computer files reveal the targets of the Jordanian plot. [Cooley, 2002, pp. 33] According to contemporary press accounts, Deek, who was running a computer repair shop in Peshawar, Pakistan, had helped encrypt al-Qaeda’s Internet communications and smuggled recruits to al-Qaeda training camps in Afghanistan. Some reports identify him as a former mujaheddin fighter, a US Army veteran, and a close associate of Osama bin Laden. Articles also claim he worked closely with al-Qaeda leader Abu Zubaida on the Jordanian plot and other things (see May 2000, Late 1980s, and 1998-December 11, 1999). [Orange County Weekly, 6/15/2006] CNN says Deek “is believed to be the mastermind” of the Jordanian plot. [CNN, 12/17/1999] But, unlike the rest of the defendants in the Jordanian case, Deek is transferred from a maximum-security prison to a minimum-security one. He alone is not charged. He will be released in May 2001 (see May 2001). [Orange County Weekly, 6/15/2006] It will later be alleged that Deek was a Jordanian intelligence mole (see Shortly After December 11, 1999).
December 14, 1999: Al-Qaeda Operative Planning LA Airport Attack Is Arrested
Al-Qaeda operative Ahmed Ressam is arrested in Port Angeles, Washington, attempting to enter the US with components of explosive devices. One hundred and thirty pounds of bomb-making chemicals and detonator components are found inside his rental car. He subsequently admits he planned to bomb Los Angeles International Airport on December 31, 1999. [New York Times, 12/30/2001] Alert border patrol agent Diana Dean stops him; she and other agents nationwide had been warned recently to look for suspicious activity. Ressam’s bombing would have been part of a wave of attacks against US targets over the New Year’s weekend (see December 15-31, 1999). He is later connected to al-Qaeda and convicted. [US Congress, 9/18/2002; PBS Frontline, 10/3/2002]
December 14-25, 1999: Private Investigators Discover Al-Qaeda Sleeper Cell in California
Counterterrorism “tsar” Richard Clarke, hearing about Ahmed Ressam’s arrest earlier in the day (see December 14, 1999), hires a team of private terrorism analysts to complete a report on militant Islamic cells in North America. The Investigative Project on Terrorism, led by Steven Emerson, finishes the report just prior to the end of the year, hoping to help stop any millennium plots. [New Yorker, 5/29/2006] Investigator Rita Katz discovers that a man named Khalil Deek who has just been arrested in Jordan for a role in a millennium plot is a US citizen (see December 11, 1999). Using only public records, she begins looking into Deek’s activities in the US. She believes that she discovers a sleeper cell consisting of: [Katz, 2003, pp. 161-162] 
Khalil Deek. He is an al-Qaeda operative who has lived in Anaheim, California, for most of the 1990s. A former senior CIA official will later claim that Deek’s extremist connections were already “well established in the classified intelligence” by this time, and in fact, it will later be reported that Deek’s connections with al-Qaeda leader Abu Zubaida had been investigated since the late 1980s (see Late 1980s). Katz learns from intelligence reports that Deek has connections to a militant cell based in Montreal, Canada that includes Ressam. She suspects that Deek is coordinating al-Qaeda groups in North America. [LA Weekly, 9/15/2005; New Yorker, 1/22/2007] Deek regularly wires tens of thousands of dollars to overseas destinations. Business records show Deek was still in Anaheim as late as August 1998. The research team discovers Deek may have been visiting the US as late as September 1999. [US Congress, 1/25/2000; Orange County Weekly, 6/15/2006] Hisham Diab. Katz learns that Diab is Deek’s next door neighbor in Anaheim and she suspects the two of them have been operating a sleeper cell there (in fact, Diab’s wife had already repeatedly tried to warn the FBI about her husband, to no avail (see March 1993-1996). [LA Weekly, 9/15/2005] She discovers that Deek and Diab have formed a charity front called Charity Without Borders (this group received a $75,000 state grant in 1997 to distribute fliers encouraging the recycling of used motor oil). [LA Weekly, 9/15/2005; Orange County Weekly, 6/15/2006] Tawfiq Deek, Khalil Deek’s brother. Katz discovers that Tawfiq has presented himself as the Islamic Association for Palestine (IAP) spokesman in California. Katz calls the IAP the “Hamas front in America.” [Katz, 2003, pp. 167] Khalid Ashour, a Palestinian. He had lived in the same apartment building as the Deek brothers and Diab, and also worked with the IAP. But what most interests Katz is that he had been heavily involved in the Islamic Center of Tuscon in the early 1990s. The Islamic Center is important for the IAP but is also believed to be the focal point for al-Qaeda’s first base in the US (see 1994). Katz discovers that he had been arrested in 1991 trying to enter the US with a fake ID and border guards found handbooks of explosives and bombs in his car. In 1999, he had moved nearly half a million dollars out of the US despite holding a job that only paid $600 a week. [Katz, 2003, pp. 167-168] Although Katz does not discover it at the time, another associate of the Deeks and Diab in Anaheim named Adam Gadahn will later emerge as a prominent al-Qaeda spokesman in Afghanistan (see Spring 2004).
Katz, Emerson, and other members of the Investigative Project on Terrorism will brief members of the National Security Council about what they learned on December 25, 1999, but no action will be taken against the suspects they have uncovered (see December 25, 1999).
December 15-31, 1999: US Intelligence Launches Worldwide Effort to Thwart Millennium Attack Plots
In the wake of the arrest of Ahmed Ressam (see December 14, 1999), FBI investigators work frantically to uncover more millennium plots before the end of the year. US authorities also make a number of arrests. A telephone number found in Ressam’s pocket leads to Abdel Ghani Meskini, an Algerian living in New York City who had gone to Seattle to meet Ressam. Meskini is monitored and arrested in New York on December 30. One of Ressam’s credit cards leads to the arrest of Mokhtar Haouari, an Algerian living in Montreal, Canada. Meskini later cooperates with US investigators and is never charged, while Haouari will be sentenced to 24 years in prison. [Time, 2/7/2000; CNN, 1/16/2002; Wright, 2006, pp. 298] Another Algerian associate of Ressam’s, Abdelmajid Dahoumane, escapes to Afghanistan, but will eventually be caught by the Algerian government and convicted in Algeria. [PBS Frontline, 10/25/2001] Investigators believe that Mohamedou Ould Slahi, an al-Qaeda operative whose cousin is a top al-Qaeda leader, went to Canada to give the go-ahead for Ressam’s attack. Slahi is arrested several times overseas, but never charged (see January-April 2000). [CNN, 3/6/2002] Khalid Deek, a US citizen, is arrested around this time for masterminding another al-Qaeda millennnium plot (see December 11, 1999). But counterterrorism expert Rita Katz will later say Deek was a suspected mastermind of Ressam’s Los Angeles airport plot, too. [Orange County Register, 9/12/2005] Deek’s name and phone number is found in Ressam’s telephone book. Ressam knew Deek from bin Laden training camps in Afghanistan. Both of them, like most of Ressam’s group, have links to the GIA, an Algerian militant group associated with al-Qaeda. [Newsweek (International), 3/13/2000]
Others escape the US after hearing media reports of Ressam’s arrest. However, enough people are caught to stop additional millennium attacks. Counterterrorism “tsar” Richard Clarke later says, “I think a lot of the FBI leadership for the first time realized that… there probably were al-Qaeda people in the United States. They realized that only after they looked at the results of the investigation of the millennium bombing plot.” [PBS Frontline, 10/3/2002] Yet Clinton’s National Security Adviser Sandy Berger later claims that the FBI will still repeatedly assure the Clinton White House until Clinton leaves office that al-Qaeda lacks the ability to launch a domestic strike (see 2000).
December 21, 1999: FBI Misses Chance to Discover Moussaoui’s Al-Qaeda Connections
The FBI misses a chance to learn about Zacarias Moussaoui after a raid in Dublin, Ireland. On December 14, 1999, Ahmed Ressam was arrested trying to smuggle explosives into the US (see December 14, 1999). On December 21, Irish police arrest Hamid Aich and several other North African immigrants living in Dublin. [New York Times, 1/22/2000] During the arrests, police seize a large amount of documents relating to citizenship applications, identities, credit cards, and airplane tickets. A diagram of an electrical switch that could be used for a bomb is found that is identical to a diagram found in Ressam’s apartment in Vancouver, Canada. [Irish Times, 7/31/2002] The suspects are released about a day later, but, “Within days, authorities in Ireland and the United States began to realize that they might have missed a chance to learn more about a terrorist network.” [New York Times, 1/22/2000] It is discovered that Aich lived with Ressam in Montreal, and then later lived with him in Vancouver. Investigators conclude there has been an al-Qaeda cell in Dublin since the early 1990s, when the charity Mercy International opened an office there (this charity has several known al-Qaeda connections by this time (see 1988-Spring 1995 and Late 1996-August 20, 1998) and also an alleged CIA connection (see 1989 and After)). The cell is mainly involved in providing travel and identity documents for other cells committing violent acts. Investigators also connect Aich to the Islamic Jihad. But the US and Canada do not seek Aich’s extradition, and instead have the Irish police keep him under surveillance. He will escape from Ireland shortly before 9/11 (see June 3, 2001-July 24, 2001). [New York Times, 1/22/2000; Irish Times, 7/31/2002] Apparently, many of the documents seized in the raid will only be closely examined after 9/11. Documents will show that in 1999 and 2000, Mustafa Ahmed al-Hawsawi, a top al-Qaeda financier, worked with the Dublin cell to finance Moussaoui’s international travel. Aich made travel arrangements and possibly provided fake identification for Moussaoui. [Fox News, 7/30/2002; Irish Times, 7/31/2002] Presumably, had these links been discovered after the 1999 raid instead of after 9/11, events could have gone very differently when Moussaoui was arrested in the US in August 2001 (see August 16, 2001).
