Fifty to sixty CIA officers read cables reporting on travel by 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi. The cables are generated in connection with al-Qaeda’s Malaysia summit, which Almihdhar and Alhazmi attend and the CIA monitors (see January 5-8, 2000). Even though some of the cables state that Almihdhar has a US visa and Alhazmi has arrived in the US, the FBI is not informed of this (see, for example, January 6, 2000 and March 5, 2000), and the two men are not watchlisted until the summer of 2001 (see August 23, 2001). The cables are drafted at four field offices and at headquarters and are read by overseas officers, headquarters personnel, operations officers, analysts, managers, junior employees, CIA staff, and officers on attachment from the NSA and FBI. The CIA’s inspector general will comment: “Over an 18-month period, some of these officers had opportunities to review the information on multiple occasions, when they might have recognized its significance and shared it appropriately with other components and agencies.” [Central Intelligence Agency, 6/2005, pp. xiv

January 15, 2000: 9/11 Hijackers Alhazmi and Almihdhar Arrive in US
A week after attending the al-Qaeda summit in Malaysia (see January 5-8, 2000), 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar fly together from Bangkok, Thailand, to Los Angeles, California. [MSNBC, 12/11/2001] The passports of both men have indicators of their terrorist affiliation placed there by Saudi authorities to track them (see March 21, 1999 and April 6, 1999), but the indicators are apparently not noticed by US immigration officials, as they have not been informed of their significance (see Around February 1993). [9/11 Commission, 8/21/2004, pp. 10 ] The CIA will later claim that it lost track of them when they arrived in Bangkok and that it did not receive notification from the Thai government that Almihdhar and Alhazmi entered the US until March 2000 (see March 5, 2000). However, Almihdhar will later tell 9/11 mastermind Khalid Shaikh Mohammed that he and Alhazmi think they were watched and followed from Bangkok to Los Angeles by unknown individuals (see Mid-July 2000). [9/11 Commission, 7/24/2004, pp. 181, 215] One San Diego friend of the two hijackers, Mohdar Abdullah, will later allegedly claim that he was told in advance they were coming to Los Angeles to carry out an attack in the US (see Early 2000).
January 15, 2000: Thai Authorities Note 9/11 Hijackers Alhazmi and Almihdhar Depart Bangkok for US, Unclear Whether CIA Informed
Thai authorities note that 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi depart Bangkok, Thailand, for the US (see January 15, 2000). They had been put on a Thai watch list shortly before this at the CIA’s request (see January 13, 2000), but the watchlisting only means the Thais note their departure from Thailand—they are not stopped at the airport. The reason for the watchisting was that the CIA was unable to locate them in Thailand, and wanted to be notified of the two future 9/11 hijackers’ departure, so it could start tracking them again. However, it is unclear whether this information is passed to the CIA at this time. One possibility is that the Thais do not pass this information on and, according to author James Bamford, “[What’s] worse, the CIA didn’t bother to ask for it until months later.” When the CIA asks for the information in February, only one of the names, Alhazmi’s, is allegedly passed to CIA headquarters (see March 5, 2000). [Bamford, 2004, pp. 230; 9/11 Commission, 1/26/2004, pp. 6 ]
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).
January 15-February 2000: Suspected Advance Man Al-Bayoumi Helps 9/11 Hijackers Settle in San Diego
Omar al-Bayoumi, a suspected Saudi spy, goes to great lengths to help future 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar settle in San Diego. Supposedly, al-Bayoumi meets them by chance in a Los Angeles restaurant and encourages them to move to San Diego, but the accounts of the meeting are highly doubtful (see February 1, 2000). The FBI’s “best source” in San Diego will later say that al-Bayoumi “must be an intelligence officer for Saudi Arabia or another foreign power.” A former top FBI official working on the al-Bayoumi investigation claims, “We firmly believed that he had knowledge [of the 9/11 plot], and that his meeting with them that day was more than coincidence.” [Newsweek, 7/28/2003] When Alhazmi and Almihdhar move into apartment 150 in the Parkwood Apartments in San Diego in early February, they indicate on their rental application that they have been staying at al-Bayoumi’s apartment in the same apartment complex since January 15, the day they arrived in the US (see January 15-February 2, 2000). (This would suggest the alleged accidental restaurant meeting never took place.) [Federal Bureau of Investigation, 10/3/2001 ] He is the co-signer and guarantor for their rental application, because they do not have established credit. [Federal Bureau of Investigation, 10/3/2001 ] He pays $1,500 cash for their first month’s rent and security deposit. Some FBI officials claim the hijackers immediately pay him back, others claim they do not. [Newsweek, 11/24/2002; US Congress, 7/24/2003 ] The apartment manager will later claim al-Bayoumi occasionally paid rent for Alhazmi and Almihdhar on other occasions. [Federal Bureau of Investigation, 10/3/2001 ] Shortly after they arrive in San Diego, al-Bayoumi throws a welcoming party to introduce them to the local Muslim community. [Washington Post, 12/29/2001] One attendee will later say an al-Bayoumi party “was a big deal… it meant that everyone accepted them without question.” [San Diego Union-Tribune, 10/25/2001] He also introduces hijacker Hani Hanjour to the community a short time later, and Hanjour is seen in his apartment later in the year (see Early 2000). [San Diego Union-Tribune, 9/14/2002] Cayson Bin Don, a friend of al-Bayoumi, will later say al-Bayoumi “spent a lot of time at Alhazmi and Almihdhar’s apartment.” [Federal Bureau of Investigation, 10/8/2001 ] Al-Bayoumi apparently loans the hijackers his cell phone until they can get phone service in their own apartment. On February 15, 2000, someone trying to call al-Bayoumi on his phone has the call answered by Alhazmi instead. [9/11 Commission, 7/24/2004, pp. 516] He tasks an acquaintance, Mohdar Abdullah, to serve as their translator and help them get driver’s licenses, Social Security cards, information on flight schools, and more. [San Diego Union-Tribune, 9/14/2002; US Congress, 7/24/2003 ]
January 15-February 2, 2000: 9/11 Hijackers Alhazmi and Almihdhar Allegedly Stay in Omar Al-Bayoumi’s Apartment
An FBI document from shortly after 9/11 states, “Rental records for the Parkwood Apartments [in San Diego] indicate that, prior to moving into apartment 150, hijackers Nawaf Alhazmi and Khalid Almihdhar lived with Omar al-Bayoumi” in apartment 152 at the same apartment complex. [Federal Bureau of Investigation, 10/3/2001 ] An FBI timeline put together later that month further clarifies that on a rental application on February 5, 2000, the two hijackers specified they had lived with al-Bayoumi from January 15 to February 2. [Federal Bureau of Investigation, 10/2001, pp. 52 ] January 15 is the same day the two hijackers arrive in the US (see January 15, 2000), which suggests the hijackers immediately went from the Los Angeles airport to al-Bayoumi’s apartment. Al-Bayoumi, a suspected Saudi intelligence agent, will later claim he only meets the hijackers by chance at a Los Angeles restaurant two weeks later (see February 1, 2000).
After January 15, 2000: 9/11 Hijacker Alhazmi Allegedly Suspects Omar Al-Bayoumi Is Saudi Spy
After getting to know San Diego resident Omar al-Bayoumi, future 9/11 hijacker Nawaf Alhazmi allegedly begins to suspect that he is a Saudi spy. Alhazmi, fellow hijacker Khalid Almihdhar, and al-Bayoumi all live in the Parkwood Apartments in San Diego in early 2000 (see January 15-February 2, 2000 and January 15-February 2000). In discussing why the hijackers move from there, the 9/11 Commission will comment, “They may also have been reconsidering the wisdom of living so close to the video camera-wielding al-Bayoumi, who Alhazmi seemed to think was some sort of Saudi spy.” [9/11 Commission, 7/24/2004, pp. 219]
Alhazmi Warns Friend Al-Bayoumi Is a Spy – An FBI report from shortly after 9/11 obtained by the website Intelwire.com will similarly mention, “Alhazmi disclosed to _____ [that al-Bayoumi] was a spy for the Saudi government and directed ______ not to socialize too much with him.” (Several names mentioned are redacted, and al-Bayoumi’s name is inferred from other references to him.) [Federal Bureau of Investigation, 4/15/2002 ] It is unclear what the source for this information is, or when exactly Alhazmi may say this.
Alhazmi Also Tells FBI Informant Al-Bayoumi Is a Spy – From May until December 2000, Alhazmi lives at the house of Abdussattar Shaikh, an FBI informant. In a 2004 interview by the 9/11 Commission, Shaikh will say that Alhazmi told him that al-Bayoumi was an agent for the Saudi government. Alhazmi also told him that he didn’t like al-Bayoumi, and he complained that al-Bayoumi constantly videotaped people at the local mosque, and made comments on the video camera’s microphone as he recorded them. Shaikh already knew al-Bayoumi from the local mosque (the Islamic Center of San Diego) and al-Bayoumi also visited Alhazmi at his house. Shaikh pointed out that he’d noticed this too, and he says he told Alhazmi, “I have heard that al-Bayoumi is an agent (of the Saudis).” Later, Shaikh warned someone he knew not to help al-Bayoumi after being requested to do so, because he feared al-Bayoumi was an intelligence agent. [9/11 Commission, 4/23/2004]
Others Concur Al-Bayoumi Was a Spy – Many US investigators will later conclude that al-Bayoumi is in fact a Saudi spy (see August 1-3, 2003 and September 7, 2004). Furthermore, some FBI officials will allegedly conclude that Alhazmi and Almihdhar also are connected to Saudi intelligence (see 2006 and After and August 6, 2003).
Early 2000-Summer 2001: NSA Intercepts Communications between 9/11 Hijackers in US and Al-Qaeda Communications Hub
While the 9/11 hijackers are in the US, the NSA intercepts several calls between them and an al-Qaeda communications hub in Sana’a, Yemen, run by Ahmed al-Hada, who is hijacker Khalid Almihdhar’s father-in-law (see August 4-25, 1998).
Summary of Calls – The first calls are made by Almihdhar and are intercepted during the spring and summer of 2000 (see Spring-Summer 2000). More calls are made by hijacker Nawaf Alhazmi after the bombing of the USS Cole in October 2000 (see Mid-October 2000-Summer 2001). The final call from the US is intercepted just a few weeks before 9/11 (see (August 2001)).
The NSA intercepted the hijackers’ calls outside the US before this (see Early 1999 and December 29, 1999) and continues to do so in 2000 (see Summer 2000) after Almihdhar returns to Yemen (see June 10, 2000 and (Mid-June-Mid-July 2000)).
Calls’ Content – Some of the calls may only contain non-operational information, as they are reportedly between Almihdhar and his wife. [9/11 Commission, 7/24/2004, pp. 222; Suskind, 2006, pp. 94; Wright, 2006, pp. 343] However, the calls are also used to relay messages to the 9/11 hijackers. [Embassy of Yemen (Washington), 2/13/2002; MSNBC, 2/14/2002; MSNBC, 5/2005]
Agencies’ Roles – The CIA is the lead agency monitoring the communications hub. It has planted bugs inside it and is wiretapping all calls (see Late August 1998). Intercepts of calls to and from the hub are a major plank of the US intelligence community’s effort to fight al-Qaeda. Also involved is the FBI, which is using phone records to plot these calls on a map (see Late 1998-Early 2002). Some of the calls intercepted by US intelligence come from Osama bin Laden’s satellite phone in Afghanistan (see August 4-25, 1998 and Late August 1998). After 9/11, counterterrorism officials will say that the number was one of the hottest targets being monitored by the NSA and was an “intelligence bonanza.” [Los Angeles Times, 12/21/2005; Wright, 2006, pp. 343]
Importance of Failure – Also after 9/11, counterterrorism officials will agree that the failure to follow leads to the US from this number was a huge missed opportunity to stop the 9/11 plot. For instance, FBI agent Kenneth Maxwell will say: “Two al-Qaeda guys living in California—are you kidding me? We would have been on them like white on snow: physical surveillance, electronic surveillance, a special unit devoted entirely to them.” [MSNBC, 7/21/2004; New Yorker, 7/10/2006 ]
Discussed after 9/11 – The failure to roll up the plot based on these communications intercepts will be discussed following 9/11 (see Summer 2002-Summer 2004 and March 15, 2004 and After).
February 2000: CIA Obtains Videotape from Al-Qaeda Summit in Malaysia, But Shows Little Interest in It
About a month after the Malaysia al-Qaeda summit (see January 5-8, 2000), “The CIA obtain[s] a surveillance videotape” from Malaysian intelligence “that shows men arriving at the meeting, according to a US intelligence official. The tape, he said, has no sound and [isn’t] viewed as very significant at the time.” [Los Angeles Times, 10/14/2001] Apparently, only the first day of the summit was videotaped (see January 5, 2000). Contents of the tape, which might definitively prove who was at the meeting, have never been made public, but the US Treasury will later mention that al-Qaeda leader Hambali and 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar were on the tape. [US Department of the Treasury, 1/24/2003 ] There is no evidence the CIA shares the videotape with any other agency before 9/11, and it has never been made public.
February-August 2000: 9/11 Hijackers Alhazmi and Almihdhar Have Closed-Door Meetings with Al-Qaeda Imam in San Diego
Future 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar attend a San Diego mosque whose imam is Anwar al-Awlaki, and they have closed-door meetings with him. Al-Awlaki preaches at the Al-Ribat Al-Islami (also known as Rabat) mosque in La Mesa, a town right next to San Diego. After 9/11, the FBI will question al-Awlaki, and he will admit to meeting with Alhazmi several times, but say he does not remember what they discussed. He will not claim to remember Almihdhar at all. [9/11 Commission, 7/24/2004, pp. 221] However, other accounts will suggest there is a much closer relationship, and with both hijackers. It is uncertain when they first meet, but a series of phone calls on February 4, 2000 connects the two hijackers, al-Awlaki, and a suspected Saudi spy named Omar al-Bayoumi (see February 4, 2000). The 9/11 Congressional Inquiry will later report that Alhazmi and Almihdhar “were closely affiliated with [al-Awlaki] who reportedly served as their spiritual adviser during their time in San Diego.… Several persons informed the FBI after September 11 that this imam had closed-door meetings in San Diego with Almihdhar, Alhazmi, and another individual, whom al-Bayoumi had asked to help the hijackers.” [US Congress, 7/24/2003 ]
Abdullah in Closed-Door Meetings? – This other person may be Mohdar Abdullah. Interviewed after 9/11, Abdullah will claim that al-Bayoumi specifically asked him “to be the individual to acclimate the hijackers to the United States, particularly San Diego, California.” [9/11 Commission, 7/24/2004, pp. 513] Furthermore, one witness will later claim to have met Alhazmi through both al-Awlaki and Abdullah. [9/11 Commission, 7/24/2004, pp. 513] Abdullah may be told of the 9/11 plot in the spring of 2000 (see Early 2000), so presumably he could be a participant in secret meetings.
Investigator Confirms Closed-Door Meetings – Ray Fournier, a State Department official who will investigate al-Awlaki after 9/11, will say: “He was meeting with al-Hazmi and al-Mihdhar in the ante room off of the Rabat mosque. Just the three of them. It stands to reason that when three people get together and two of them end up being hijackers that end up in the Pentagon, they’re obviously discussing how they’re going to stay on track.… He’s absolving them of their sins. He’s making sure that their cover within Western culture is being maintained. He’s making sure they’re going to stay operational.” Fournier also claims that al-Awlaki was radicalized before the hijackers came to San Diego. [KPBS, 6/10/2010]
Hijackers and Al-Awlaki Reunite in Virginia – Around August 2000, al-Awlaki resigns as imam and travels to unknown “various countries.” In early 2001, he will be appointed the imam to a much larger mosque in Falls Church, Virginia. [Copley News, 10/1/2001] Alhazmi, Almihdhar, and fellow hijacker Hani Hanjour will move to Virginia and attend al-Awlaki’s mosque there (see March 2001 and After). By 2008, US intelligence will conclude that al-Awlaki is an al-Qaeda operative (see February 27, 2008).
