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).
January 5-6, 2000: Al-Qaeda Operatives’ Failure to Meet in Singapore Has Important Consequences
On January 5, 2000, al-Qaeda operatives Ibrahim al-Thawar and Fahad al-Quso arrive in Bangkok, Thailand. They were part of an attempt to sink the USS The Sullivans, which failed in Yemen just a couple of days ago (see January 3, 2000). Al-Qaeda leader Khallad bin Attash has been a part of the same plot, and has been in Kuala Lumpur, Malaysia, for the past two weeks or so (see Mid-December 1999). Al-Thawar and al-Quso are bringing thousands of dollars for bin Attash (different accounts will name different amounts, but it could be as much as $36,000), and they plan to meet in Singapore. However, all three of them are unable to get Singapore visas. Bin Attash is attending an important al-Qaeda summit in Kuala Lumpur from January 5 to 8 (see January 5-8, 2000), and Malaysia does not require visas at all for most Middle Eastern countries. However, for whatever reason, bin Attash flies to Bangkok on January 6, instead of having one or both of the others fly to Kuala Lumpur. Apparently, the money is handed over and bin Attash flies back to Kuala Lumpur the next day to continue with the summit (see January 6, 2000). [9/11 Commission, 7/24/2004, pp. 159]
Important Consequences – These interactions will have important consequences, because al-Quso will be questioned by the FBI in Yemen later in 2000 (see Late October-Late November 2000), after taking part in the bombing of the USS Cole there (see October 12, 2000). Al-Quso will confess to giving a large sum of money to bin Attash (see Early December 2000), and FBI agents will discover phone calls between al-Quso’s Bangkok hotel and a phone booth in front of the condominium where the al-Qaeda summit was held (see (January 5-8, 2000)). But the FBI agents will be unable to find out about the summit, and the CIA will not share the information it has about it, ruining a chance for the FBI to discover the 9/11 plot that had been discussed at the summit (see for instance April 2001).
January 5-8, 2000: CIA Fails to Act on Triangle of Calls Linking Malaysia Summit,ColeBomber’s House, and 9/11 Hijackers’ Hotel
A series of calls by al-Qaeda operatives, some of whom are under surveillance by the CIA and the Malaysian Special Branch at this time, links three sites involved in the bombing of the USS Cole. Even though the CIA is aware of the calls, it will later say it is unable to find the hijackers in Bangkok, the location of one of the call sites. The calls made by the operatives are between the following three locations: 
A payphone in Kuala Lumpur, Malaysia, near an apartment where about a dozen al-Qaeda operatives are holding a summit (see January 5-8, 2000); The Washington Hotel in Bangkok, Thailand. Al-Qaeda operatives Ibrahim al-Thawar and Fahad al-Quso are staying at the hotel around this time (see January 5-6, 2000). They will go on to be involved in the Cole bombing (see October 12, 2000). They are later joined in the hotel by summit attendees Nawaf Alhazmi, Khalid Almihdhar, and Khallad bin Attash; Al-Quso’s house in Yemen. The calls from the payphone to this location are made by bin Attash.
Although bin Attash and possibly others call the Washington Hotel while they are under surveillance, the CIA will be unable to locate them there during the week they spend in Bangkok, from January 8-15 (see January 13, 2000). Author Lawrence Wright will comment, “Although the CIA later denied that it knew anything about the phone, the number was recorded in the Malaysians’ surveillance log, which was given to the agency.” [9/11 Commission, 7/24/2004, pp. 156-160, 181-2; New Yorker, 7/10/2006 ] The FBI team investigating the Cole bombing will later learn some of this information before 9/11 and ask the CIA for details. However, the CIA will fail to disclose what it knows about the Malaysia summit or that it looks for the hijackers and associates in Thailand after January 8 (see July 2001).
January 8-15, 2000: 9/11 Hijackers Associate withColeBombers in Thailand
While in Thailand, 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi associate with three of the operatives who will later be involved in the bombing of the USS Cole (see October 12, 2000). The two hijackers arrive with Khallad bin Attash, who will command the Cole operation. The three of them come from Malaysia, where they were under surveillance by the CIA (see January 5-8, 2000 and January 8, 2000). While in Bangkok, bin Attash meets Cole bombers Fahad al-Quso and Ibrahim al-Thawar, who give bin Attash some money, possibly $36,000. Some of this may be passed to Alhazmi and Almihdhar. Under interrogation after 9/11, bin Attash will claim that, even though they all stay in the same hotel for part of the time (see (January 5-8, 2000)) the two groups do not meet. However, such statements are thought to be unreliable because of the methods used to extract them (see June 16, 2004). [9/11 Commission, 1/26/2004 ; 9/11 Commission, 7/24/2004, pp. 159; Wright, 2006, pp. 312] Shown photographs of Alhazmi and Almihdhar after 9/11 by the FBI, al-Quso will say that he recognizes the two, but indicate that this may be because he met them at camps in Afghanistan. [New Yorker, 7/10/2006 ] However, he is apparently photographed by Malaysian authorities standing next to Almihdhar in Kuala Lumpur (see (January 5-8, 2000)).
October 12, 2000: USS Cole Bombed by Al-Qaeda
The USS Cole is bombed in the Aden, Yemen harbor by two al-Qaeda militants, Hassan al-Khamri and Ibrahim al-Thawar (a.k.a. Nibras). Seventeen US soldiers are killed and 30 are wounded. The CIA will later conclude that with just slightly more skilled execution, the attack would have killed 300 and sunk the ship. [ABC News, 10/13/2000; Coll, 2004, pp. 532; 9/11 Commission, 7/24/2004, pp. 191] The Islamic Army of Aden (IAA) immediately takes credit for the attack. This is a Yemen-based Muslim militant group widely believed to have close ties to al-Qaeda (see 1996-1997 and After). [Guardian, 10/14/2000] The IAA statement is released by its spokesman, Abu Hamza al-Masri (see Early 1997, (June 1998), and December 28, 1998 and After). Abu Hamza says that the attack was timed to mark the anniversary of the execution of the IAA’s former commander (see October 17, 1999). [O’Neill and McGrory, 2006, pp. 184] The prime minister of Yemen at the time of the bombing will say shortly after 9/11, “The Islamic Army was part of al-Qaeda.” [Guardian, 10/13/2001] The US soon learns the names of some al-Qaeda operatives involved in the attack, including Khalid Shaikh Mohammed, Tawfiq bin Attash and Fahad al-Quso (see Early December 2000), and Abd al-Rahim al-Nashiri (see November-December 2000). 9/11 hijackers Ramzi bin al-Shibh (see October 10-21, 2000) and Khalid Almihdhar (see Around October 12, 2000) may also have been involved. This is a repeat of a previously attempted attack, against the USS The Sullivans, which failed and was apparently undetected (see January 3, 2000). [Los Angeles Times, 12/22/2002] The 9/11 Commission will later say the Cole bombing “was a full-fledged al-Qaeda operation, supervised directly by bin Laden. He chose the target and location of the attack, selected the suicide operatives, and provided the money needed to purchase explosives and equipment.” [9/11 Commission, 7/24/2004, pp. 190]
August 28, 2001: FBI Headquarters Asks New York Office to Open Intelligence Investigation into 9/11 Hijacker Almihdhar
FBI headquarters agent Dina Corsi asks the FBI’s New York field office to open an intelligence investigation into future 9/11 hijacker Khalid Almihdhar and locate him in the US. Corsi’s written request mentions Almihdhar’s arrival in the US in July 2001 (see July 4, 2001), his previous travel to the US in January 2000 with Nawaf Alhazmi (see January 15, 2000), his attendance at al-Qaeda’s Malaysia summit (see January 5-8, 2000), his association with an al-Qaeda communications hub in Yemen (see Early 2000-Summer 2001), and similarities between his travel and that of Fahad al-Quso, Ibrahim al-Thawar (a.k.a. Nibras), and Khallad bin Attash (see January 13, 2000), operatives involved in the bombing of the USS Cole. Corsi does not mention that the CIA knows bin Attash also attended the Malaysia summit, as this information has not officially been passed to the FBI yet. [US Department of Justice, 11/2004, pp. 304 ]
