The Washington Post refers to hijackers Nawaf Alhazmi and Khalid Almihdhar when it later reports, “In November 1999, two Saudi Arabian men moved into a ground-floor apartment at the Parkwood Apartments, a town house complex near a busy commercial strip in San Diego.” [Washington Post, 9/30/2001] Alhazmi’s name is on the apartment lease beginning in November 1999. [Washington Post, 10/2001] The Los Angeles Times similarly notes, “A man by [the name Alhazmi] moved to the Parkwood Apartments in San Diego in 1999, according to manager Holly Ratchford.” [Los Angeles Times, 9/15/2001] Some reports even have them visiting the US as early as 1996. [Wall Street Journal, 9/17/2001; Las Vegas Review-Journal, 10/26/2001] However, FBI Director Mueller has stated the two hijackers did not arrive in the US until the middle of January 2000, after attending an important al-Qaeda summit in Malaysia (see January 5-8, 2000). While some news reports mention that the hijackers first arrive in late 1999 [Los Angeles Times, 9/1/2002; Los Angeles Times, 11/24/2002] , over time, mentions of the lease beginning in 1999 will slowly fade from media accounts.
Late 1999: 9/11 Hijackers Train withColeBomber and Other Militants
A group of al-Qaeda operatives receives advanced training at the Mes Aynak camp in Afghanistan. The large group includes 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar (see November/December 1999), al-Qaeda commander Khallad bin Attash, would-be 9/11 hijacker Abu Bara al-Taizi (a.k.a. Zohair Mohammed Said), USS Cole bomber Ibrahim al-Thawar (a.k.a. Nibras), an operative who leads a series of suicide bombings in Riyadh in 2003, and another who is involved against the 2002 attack against a ship called the Limburg (see October 6, 2002). According to statements by detainees, the course focuses on physical fitness, firearms, close quarters combat, shooting from a motorcycle, and night operations. Osama bin Laden and Khalid Shaikh Mohammed (KSM) apparently visit the camp during the course. [9/11 Commission, 7/24/2004, pp. 157; Office of the Director of National Intelligence, 9/6/2006, pp. 12 
] Candidate hijacker Abderraouf Jdey, a Canadian passport holder, may also be present at this training course. [9/11 Commission, 7/24/2004, pp. 527] Also, in early December, KSM gives special hijacking training to Alhazmi, bin Attash, and al-Taizi (see Early December 1999).
Late 1999: Saudis Claim to Add Two 9/11 Hijackers to Watch List and Inform CIA
Prince Turki al-Faisal, Saudi intelligence minister until shortly before 9/11 (see August 31, 2001), will later claim that around this time its external intelligence agency tells the CIA that hijackers Nawaf Alhazmi and Khalid Almihdhar have been put on a Saudi terror watch list. The Saudis have been tracking the two men, as well as Nawaf’s brother Salem, for some time (see March 21, 1999, April 4, 1999, April 6, 1999, and After Early April 1999). Saeed Badeeb, Turki’s chief analyst, and Nawaf Obaid, a security consultant to the Saudi government, support Turki’s account though Turki himself will later back away from it after becoming Saudi ambassador to the US (see August 21, 2005). In 2003, Prince Turki will say, “What we told [the CIA] was these people were on our watch list from previous activities of al-Qaeda, in both the [1998] embassy bombings and attempts to smuggle arms into the kingdom in 1997,” (see 1997 and October 4, 2001). However, the CIA strongly denies any such warning, although it begins following Almihdhar and Alhazmi around this time (see January 2-5, 2000 and January 5-8, 2000). [Associated Press, 10/16/2003; Salon, 10/18/2003; Wright, 2006, pp. 310-311, 448] The US will not put Almihdhar and Alhazmi on its watch list until August 2001 (see August 23, 2001).
December 1999-January 2000: FBI’s New York Office Receives NSA Information on Hijackers’ Travel to Malaysia Summit
The FBI’s New York field office, which specializes in international terrorism and houses the I-49 squad that focuses on Osama bin Laden (see January 1996), receives information from the NSA about a wiretap on the phone of 9/11 hijacker Khalid Almihdhar. The information concerns travel by Almihdhar, fellow alleged hijacker Nawaf Alhazmi, and other operatives to an al-Qaeda summit in Kuala Lumpur, Malaysia (see December 29, 1999, Shortly Before December 29, 1999, and January 5-8, 2000), but the office, like the rest of the FBI, is not told Almihdhar has a US visa (see 9:30 a.m. – 4:00 p.m. January 5, 2000). However, the New York office apparently does not realize it has this information and when investigators become aware of its importance in June 2001 they will conduct a running argument with FBI headquarters and the CIA over whether they can receive it again (see June 11, 2001). [US Department of Justice, 11/2004, pp. 293 ]
Early December 1999: KSM Trains Operatives for Hijackings
Khalid Shaikh Mohammed (KSM) gives a course lasting one or two weeks for three operatives scheduled to take part in the 9/11 operation. Nawaf Alhazmi, Khallad bin Attash, and Abu Bara al-Taizi (a.k.a. Zohair Mohammed Said) learn how to say basic English words and phrases, read plane timetables and phone books, use the Internet, make travel reservations, rent an apartment, and use code words. In addition, they play flight simulator games, watch hijacking-themed films, and investigate visas for Southeast Asian countries. KSM also tells them what to watch for when casing a flight, for example whether flight attendants bring food into the cockpit. Khalid Almihdhar is apparently not present at the training, since he has just returned to Yemen (see November/December 1999). [9/11 Commission, 7/24/2004, pp. 157-8, 493]
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).
December 11, 1999: Watch List Importance Is Stressed but Procedures Are Not Followed
The CIA’s Counterterrorism Center sends a cable reminding all its personnel about various reporting obligations. The cable clearly states that it is important to share information so suspected members of US-designated terrorist groups can be placed on watch lists. The US keeps a number of watch lists; the most important one, TIPOFF, contains about 61,000 names of suspected terrorists by 9/11. [Los Angeles Times, 9/22/2002; Knight Ridder, 1/27/2004] The list is checked whenever someone enters or leaves the US. “The threshold for adding a name to TIPOFF is low,” and even a “reasonable suspicion” that a person is connected with a US-designated terrorist group warrants being added to the database. [US Congress, 9/20/2002] Within a month, two future hijackers, Nawaf Alhazmi and Khalid Almihdhar, will be identified as al-Qaeda operatives (see December 29, 1999), but the cable’s instructions will not be followed for them. The CIA will initially tell the 9/11 Congressional Inquiry that no such guidelines existed, and CIA Director Tenet will fail to mention the cable in his testimony to the Inquiry. [New York Times, 5/15/2003; US Congress, 7/24/2003, pp. 157 ]
December 29, 1999: NSA Tells CIA about Planned Al-Qaeda Summit Involving Future Hijackers
The NSA, monitoring a telephone in an al-Qaeda communications hub in Yemen (see Late August 1998 and Late 1998-Early 2002), has listened in on phone calls revealing that hijackers Khalid Almihdhar, Nawaf Alhazmi, and Salem Alhazmi are to attend an important al-Qaeda summit in Malaysia in January 2000 (see Shortly Before December 29, 1999). Almihdhar’s full name was mentioned, as well as the first names of hijackers Nawaf Alhazmi and Salem Alhazmi. On this day, the NSA shares this information with the CIA’s Alec Station bin Laden unit. Other US intelligence agencies, including FBI headquarters and the FBI’s New York field office, are told as well. Although Khalid Almihdhar’s full name was mentioned in one call, the NSA only passes on his first name. Also, the NSA has already learned from monitoring the Yemen hub that Nawaf’s last name is Alhazmi and that he is long-time friends with Almihdhar (see Early 1999). However, they either don’t look this up in their records or don’t pass it on to any other agency. [9/11 Commission, 1/26/2004, pp. 6 ; US Department of Justice, 11/2004, pp. 239 ; Wright, 2006, pp. 310] An NSA analyst makes a comment that is shared between US intelligence agencies, “Salem may be Nawaf’s younger brother.” This turns out to be correct. [US Congress, 7/24/2003, pp. 135 ; 9/11 Commission, 1/26/2004, pp. 6 ] A CIA officer will later tell the 9/11 Congressional Inquiry that information from the Africa embassy bombings (see 10:35-10:39 a.m., August 7, 1998) was reviewed in late 1999 during a worldwide effort to disrupt millennium attack plots (see December 15-31, 1999) and “a kind of tuning fork… buzzed when two [of the hijackers] reportedly planning a trip to [Malaysia] were linked indirectly to what appeared to be a support element… involved with the Africa bombers.” [US Congress, 7/24/2003, pp. 135 ] The fact that they are connected to the Yemen communication hub already indicates some importance within al-Qaeda. It is learned they are connected to the embassy bombings in some way (see October 4, 2001 and Late 1999). [US Congress, 7/24/2003, pp. 135 ; 9/11 Commission, 1/26/2004, pp. 6 ] The NSA report about them on this day is entitled, “Activities of Bin Laden Associates,” showing the clear knowledge of their ties to bin Laden. [9/11 Commission, 7/24/2004, pp. 502; Vanity Fair, 11/2004] The CIA will track Almihdhar and Nawaf Alhazmi to the Malaysia summit (see January 2-5, 2000 and January 5-8, 2000).
Shortly Before December 29, 1999: NSA Monitors 9/11 Hijackers Talking to Each Other about Upcoming Al-Qaeda Summit
The NSA has been monitoring a telephone in an al-Qaeda communications hub in Yemen (see Late August 1998 and Late 1998-Early 2002). According to Vanity Fair, “Amid the storm of pre-millennial ‘chatter,’ the [NSA] intercepted communications among three Arabic men, each of whom bore some connection to the East Africa bombings (see 10:35-10:39 a.m., August 7, 1998) and to al-Qaeda.” The men are hijackers Khalid Almihdhar, Nawaf Alhazmi, and Salem Alhazmi. [Vanity Fair, 11/2004] Apparently, the NSA listens in on a phone call between al-Qaeda figure Khallad bin Attash and hijacker Khalid Almihdhar, who is staying at the hub. Attash mentions Almihdhar’s full name, as well as the first names of hijackers Nawaf Alhazmi and Salem Alhazmi. He says he wants the three of them to come to an important al-Qaeda summit in Malaysia in January 2000 (see January 5-8, 2000). The NSA has already heard the names of the three hijackers mentioned repeatedly in 1999 while monitoring the Yemen hub (see Early 1999). Apparently, US intelligence does not yet know bin Attash’s full name or role in al-Qaeda and won’t figure it out until late 2000 (see Early December 2000). [Wright, 2006, pp. 310] At the same time, US officials in Pakistan intercept Nawaf Alhazmi in Karachi calling Almihdhar at the Yemen hub. They learn Nawaf is planning a trip to Malaysia on January 4, 2000. The NSA is also monitoring Nawaf calling his brother Salem (the location of Salem at this time has not been revealed). [US Congress, 7/24/2003, pp. 143-144 ; Asia Times, 3/19/2004] The NSA will share details of these calls with the CIA and other agencies on December 29, 1999 (see December 29, 1999) and the CIA will eventually track Almihdhar to the Malaysia summit (see January 2-5, 2000).
