9/11 facilitators Ali Abdul Aziz Ali and Mustafa Ahmed al-Hawsawi leave the United Arab Emirates (UAE) in a hurry. At a hearing held in Guantanamo Bay in 2007 to determine Ali’s combat status, his departure from the UAE just before 9/11 will be included in the facts supporting his designation as an enemy combatant. However, he will deny having foreknowledge of 9/11 and say he had to leave the UAE as his work permit was canceled. [US Department of Defense, 4/12/2007 
] Al-Hawsawi leaves Dubai on the morning of 9/11 for Karachi. Shortly before, he had learned that the operation for which the hijackers had traveled to the US would take place on September 11, and had been advised by fellow operatives Ramzi bin al-Shibh and Khalid Shaikh Mohammed that he should return to Pakistan. [US department of Defense, 3/21/2007 ] Before leaving, al-Hawsawi transferred $40,000 the hijackers had returned to him to his Visa card (see September 5-10, 2001). He makes six ATM withdrawals on the card in Pakistan two days later and then disappears. [MSNBC, 12/11/2001]
September 10, 2001: Alleged Al-Qaeda Operative Arrives in US
Ali Saleh Kahlah al-Marri, from Qatar but a legal US resident, arrives in the US with his wife and five children, reportedly to pursue a master’s degree in computer science at Bradley University in Peoria, Illinois. [Peoria Journal Star, 12/19/2001; New York Times, 6/21/2004] Al-Marri appears to have been sent to the US by 9/11 mastermind Khalid Shaikh Mohammed (KSM). During his interrogation, KSM will identify al-Marri as “the point of contact for al-Qaeda operatives arriving in the US for September 11 follow-on operations.” He will describe al-Marri as “the perfect sleeper agent because he has studied in the United States, had no criminal record, and had a family with whom he could travel.” [Newsweek, 6/15/2003] However, there are doubts about the reliability of KSM’s interrogation, which is believed that have been obtained through the use of torture (see June 16, 2004). Al-Marri also lived in Illinois for part of 2000 under a different name. [New York Daily News, 1/11/2003] He is apparently related to Mohamed al-Khatani, who attempted to enter the US in August 2001 to join the 9/11 plot (see July 2002). [New York Times, 6/21/2004] In December 2001, al-Marri will be detained as a material witness to the 9/11 attacks (see December 12, 2001).
September 10, 2001: NSA Monitors Call as 9/11 Mastermind KSM Gives 9/11 Hijacker Atta Final Approval to Launch Attacks
9/11 hijacker Mohamed Atta calls 9/11 mastermind Khalid Shaikh Mohammed (KSM) in Afghanistan. KSM gives final approval to Atta to launch the attacks. The specifics of the conversation haven’t been released. [Independent, 9/15/2002] Unnamed intelligence officials later tell Knight Ridder Newspapers that the call is monitored by the NSA, but only translated after the 9/11 attacks. KSM, “using coded language, [gives] Atta final approval” for the attacks. [Knight Ridder, 9/9/2002] NSA monitored other calls between KSM and Atta in the summer of 2001 but did not share the information about this with other agencies (see Summer 2001). Additionally, it will later be revealed that an FBI squad built an antenna in the Indian Ocean some time before 9/11 with the specific purpose of listening in on KSM’s phone calls, so they may have learned about this call to Atta on their own (see Before September 11, 2001).
September 24, 2001-December 26, 2002: Identity of 9/11 Financier Constantly Changes
In 2000, the 9/11 hijackers receive money from a man using “Mustafa Ahmed al-Hisawi” and other aliases. On September 8-11, 2001, the hijackers send money to a man in the United Arab Emirates who uses the aliases “Mustafa Ahmed,”
“Mustafa Ahmad,” and “Ahamad Mustafa.” Soon the media begins reporting on who this 9/11 “paymaster” is, but his reported names and identities will continually change. The media has sometimes made the obvious connection that the paymaster is Saeed Sheikh—a British financial expert who studied at the London School of Economics, undisputedly sent hijacker Mohamed Atta money the month before the attacks, made frequent trips to Dubai (where the money is sent), and is known to have trained the hijackers. However, the FBI consistently deflects attention to other possible explanations, with a highly confusing series of names vaguely similar to Mustafa Ahmed or Saeed Sheikh: 
September 24, 2001: Newsweek reports that the paymaster for the 9/11 attacks is someone named “Mustafa Ahmed.” [Newsweek, 10/1/2001] This refers to Mustafa Mahmoud Said Ahmed, an Egyptian al-Qaeda banker who was captured in Tanzania in 1998 then later released. [Sydney Morning Herald, 9/28/2001; Newsday, 10/3/2001] October 1, 2001: The Guardian reports that the real name of “Mustafa Mohamed Ahmad” is “Sheikh Saeed.” [Guardian, 10/1/2001] A few days later, CNN confirms from a “senior-level US government source” that this “Sheik Syed” is the British man Ahmed Omar Saeed Sheikh rescued from an Indian prison in 1999. [CNN, 10/6/2001; CNN, 10/8/2001] However, starting on October 8, the story that ISI Director Lt. Gen. Mahmood Ahmed ordered Saeed to give Mohamed Atta $100,000 begins to break. References to the 9/11 paymaster being the British Saeed Sheikh (and the connections to the ISI Director) suddenly disappear from the Western media (with one exception [CNN, 10/28/2001] ). October 2001: Other articles continue to use “Mustafa Mohammed Ahmad” or “Shaykh Saiid” with no details of his identity, except for suggestions that he is Egyptian. There are numerous spelling variations and conflicting accounts over which name is the alias. There is an Egyptian al-Qaeda financier leader named Mustafa Abu al-Yazid who uses some variant of Saeed Sheikh as an alias. [Evening Standard, 10/1/2001; BBC, 10/1/2001; Newsday, 10/3/2001; Associated Press, 10/6/2001; Washington Post, 10/7/2001; Sunday Times (London), 10/7/2001; Knight Ridder, 10/9/2001; New York Times, 10/15/2001; Los Angeles Times, 10/20/2001] October 16, 2001: CNN reports that the 9/11 paymaster “Sheik Sayid” is mentioned in a May 2001 trial of al-Qaeda members. However, this turns out to be a Kenyan named Sheik Sayyid el Masry. [Day 7. United States of America v. Usama bin Laden, et al., 2/20/2001; United States of America v. Usama bin Laden, et al., Day 8, 2/21/2001; CNN, 10/16/2001] November 11, 2001: The identity of 9/11 paymaster “Mustafa Ahmed” is suddenly no longer Egyptian, but is now a Saudi named Sa’d Al-Sharif, who is said to be bin Laden’s brother-in-law. [United Nations, 3/8/2001; Newsweek, 11/11/2001; Associated Press, 12/18/2001] December 11, 2001: The federal indictment of Zacarias Moussaoui calls the 9/11 paymaster “Mustafa Ahmed al-Hawsawi a/k/a ‘Mustafa Ahmed,’” and gives him Sa’d’s nationality and birth date. [MSNBC, 12/11/2001] Many articles begin adding “al-Hawsawi” to the Mustafa Ahmed name. [Washington Post, 12/13/2001; Washington Post, 1/7/2002; Los Angeles Times, 1/20/2002] January 23, 2002: As new information is reported in India, the media returns to the British Saeed Sheikh as the 9/11 paymaster. [Los Angeles Times, 1/23/2002; Daily Telegraph, 1/24/2002; Independent, 1/24/2002; Daily Telegraph, 1/27/2002] While his role in the kidnapping of Daniel Pearl is revealed on February 6, many articles connect him to 9/11, but many more do not. Coverage of Saeed’s 9/11 connections generally dies out by the time of his trial in July 2002. June 4, 2002: Without explanation, the name “Shaikh Saiid al-Sharif” begins to be used for the 9/11 paymaster, presumably a combination of Saeed Sheikh and S’ad al-Sharif. [Associated Press, 6/5/2002; Independent, 9/15/2002; Associated Press, 9/26/2002; San Francisco Chronicle, 11/15/2002] Many of the old names continue to be used, however. [New York Times, 7/10/2002; Time, 8/4/2002; Los Angeles Times, 9/1/2002; Chicago Tribune, 9/5/2002; Knight Ridder, 9/8/2002; Knight Ridder, 9/9/2002; Washington Post, 9/11/2002; Los Angeles Times, 12/24/2002] June 18, 2002: FBI Director Mueller testifies that the money sent in 2000 is sent by someone named “Ali Abdul Aziz Ali” but the money in 2001 is sent by “Shaikh Saiid al-Sharif.” The 9/11 Commission will later identify Aziz Ali as Khalid Shaikh Mohammed’s nephew and agree with Mueller that he sent the money in 2000. [US Congress, 9/26/2002; 9/11 Commission, 7/24/2004, pp. 1] September 4, 2002: Newsweek says “Mustafa Ahmad Adin al-Husawi,” presumably Saudi, is a deputy to the Egyptian “Sayyid Shaikh Al-Sharif.” However, it adds he “remains almost a total mystery,” and they are unsure of his name. [Newsweek, 9/4/2002] December 26, 2002: US officials now say there is no such person as Shaikh Saiid al-Sharif. Instead, he is probably a composite of three different people: “[Mustafa Ahmed] Al-Hisawi, Shaikh Saiid al-Masri, al-Qaeda’s finance chief, and Saad al-Sharif, bin Laden’s brother-in-law and a midlevel al-Qaeda financier.” [Associated Press, 12/27/2002] Shaikh Saiid al-Masri is likely a reference the Kenyan Sheik Sayyid el Masry. Note that, now, al-Hisawi is the assistant to Shaikh Saiid, a flip from a few months before. Saiid and/or al-Hisawi still haven’t been added to the FBI’s official most wanted lists. [London Times, 12/1/2001; Federal Bureau of Investigation, 2002; Wall Street Journal, 6/17/2002] Despite the confusion, the FBI isn’t even seeking information about them. [Federal Bureau of Investigation, 2/14/2002] Mustafa Ahmed al-Hawsawi is said to be arrested with Khalid Shaikh Mohammed in Pakistan in 2003, but no photos of him are released, and witnesses of the supposed arrest did not see al-Hawsawi or Mohammed there (see February 29 or March 1, 2003). [Reuters, 3/3/2003] A few weeks later, it will be reported that “the man US intelligence officials suspected of being al-Qaeda’s financial mastermind, Sheik Said al-Masri, remains at large.” [Business Week, 3/17/2003]
Late September 2001-March 2003: US Intelligence Fails to Catch Apparent Al-Qaeda Sleeper Agent with Ties to Saudi Embassy, KSM, and CIA Charity Front
In 1993, the Al-Kifah Refugee Center in Brooklyn, New York, disbanded after media reports revealed that it had ties to all of the 1993 WTC bombers as well as the CIA (see 1986-1993), but it quickly reappeared in Boston under the new name Care International. Counterterrorism expert Steven Emerson had warned the government of the name change since 1993 (see April 1993-Mid-2003). But apparently US investigators only start looking closely at Care International shortly after 9/11, when the FBI interviews several current and former employees. [Wall Street Journal, 11/21/2001] Around the same time, the Fleet National Bank in Boston files a “suspicious-activity report” (SARS) with the US Treasury Department about wire transfers from the Saudi Embassy in Washington to Aafia Siddiqui, a long-time member of the Al-Kifah Refugee Center and then Care International, and her husband Dr. Mohammed Amjad Khan. Fleet National Bank investigators discover that one account used by the Boston-area couple shows repeated on-line credit card purchases from stores that “specialize in high-tech military equipment and apparel.” Khan purchased body armor, night-vision goggles, and military manuals, and then sent them to Pakistan. The bank also investigates two transfers totaling $70,000 sent on the same day from the Saudi Armed Forces Account used by the Saudi Embassy at the Riggs Bank in Washington to two Saudi nationals living in Boston. One of the Saudis involved in the transfers lists the same Boston apartment number as Siddiqui’s. The bank then notices that Siddiqui regularly gives money to the Benevolence International Foundation, which will soon be shut down for al-alleged Qaeda ties. They also discover her connection to Al-Kifah. The bank then notices Siddiqui making an $8,000 international wire transfer on December 21, 2001, to Habib Bank Ltd., “a big Pakistani financial institution that has long been scrutinized by US intelligence officials monitoring terrorist money flows.” [Newsweek, 4/7/2003] In April or May 2002, the FBI questions Siddiqui and Khan for the first time and asks them about their purchases. [Boston Globe, 9/22/2006] But the two don’t seem dangerous, as Siddiqui is a neuroscientist who received a PhD and studied at MIT, while Khan is a medical doctor. Plus they have two young children and Siddiqui is pregnant. There are no reports of US intelligence tracking them or watch listing them. Their whole family moves to Pakistan on June 26, 2002, but then Siddiqui and Khan get divorced soon thereafter. Siddiqui comes back to the US briefly by herself from December 25, 2002, to January 2, 2003. On March 1, 2003, Pakistan announces that 9/11 mastermind Khalid Shaikh Mohammed (KSM) has been captured (see February 29 or March 1, 2003). Some days later, Siddiqui drives away from a family house in Pakistan and disappears. Some later media reports will claim that she is soon arrested by Pakistani agents but other reports will deny it. Reportedly, KSM quickly confesses and mentions her name as an al-Qaeda sleeper agent, working as a “fixer” for other operatives coming to the US. On March 18, the FBI puts out a worldwide alert for Siddiqui and her ex-husband Khan, but Khan has completely disappeared as well. Siddiqui will be arrested in Afghanistan in 2008 (see July 17, 2008). [Vanity Fair, 3/2005] The CIA will later report that Ali Abdul Aziz Ali (a.k.a. Ammar al-Baluchi), a nephew of KSM and a reputed financier of the 9/11 attacks, married Siddiqui not long before her disappearance. Furthermore, in 2002 he ordered Siddiqui to help get travel documents for Majid Kahn (no relation to Siddiqui’s first husband), who intended to blow up gas stations and bridges or poison reservoirs in the US. It will also be alleged that Siddiqui bought diamonds in Africa for al-Qaeda in the months before 9/11. [Boston Globe, 9/22/2006] The Saudi Embassy will later claim that the wire transfers connected to Siddiqui were for medical assistance only and the embassy had no reason to believe at the time that anyone involved had any connection to militant activity. [Newsweek, 4/7/2003] Although Siddiqui seems to have ties with two key figures in the 9/11 plot and was living in Boston the entire time some 9/11 hijackers stayed there, there are no known links between her and any of the hijackers.
October 2001-February 2002: KSM’s Attempt to Duplicate 9/11 Plot on West Coast of US Fizzles
9/11 mastermind Khalid Shaikh Mohammed (KSM) attempts to organize a follow up attack to the 9/11 attacks. Beginning in October 2001, KSM and Hambali, a top al-Qaeda leader in Southeast Asia, recruit four operatives for the new plot, all of them Malaysian: Mohamad Farik Amin (a.k.a. Zubair). Mohammed Nazir Bin Lep (a.k.a. Lillie). Zaini Zakaria. Masran bin Arshad.
The plan is for these operatives to blow up the doors to airplane cockpits using shoe bombs, take over flying the aircraft, and then crash them into US buildings—essentially the same technique as was used in the 9/11 attacks, except with the addition of the shoe bomb and the use of East Asians instead of Middle Easterners. Apparently several buildings are initially targeted. KSM will later name them as the Library Tower in Los Angeles (later renamed the US Bank tower), the Sears Tower in Chicago, the Empire State Building in New York, and a tall building in Washington State. But the plot soon focuses on just the Library Tower, the tallest building on the West Coast of the US, due to a lack of pilots. The members of the plot go to Afghanistan and swear an oath of loyalty to Osama bin Laden, and then continue to train with Hambali in Asia. However, the plot does not go far because Zakaria, the only trained pilot of the group (see (Spring 2000)), drops out in late 2001, saying he has small children to consider. In February 2002, bin Arshad, the leader of the four operatives, is arrested and other other members decide the plot has been canceled. Zakaria turns himself in to Malaysian authorities in 2002, and apparently remains in detention in Malaysia without being charged. Amin and Bin Lep will be arrested in 2003 with Hambali and taken into US custody (see August 12, 2003). Amin, Bin Lep, and Hambali will all be transferred to Guantanamo prison as high-value detainees in 2006 (see September 2-3, 2006). It is unknown who arrests bin Arshad or what becomes of him.

October 4, 2001: British Prime Miniter Tony Blair Says 9/11 Hijacker Played ‘Key Role’ in Embassy Bombings
In a key speech about al-Qaeda’s responsibility for the 9/11 attacks, British Prime Minister Tony Blair says that one of the hijackers played a “key role” in the 1998 African embassy bombings (see 10:35-10:39 a.m., August 7, 1998). Though he doesn’t specify which one, he does say the individual was one of the three hijackers who were quickly identified after 9/11 as known al-Qaeda associates (see 9:53 p.m. September 11, 2001) and someone who had also played an important role in the USS Cole attacks (see October 14-Late November, 2000). [UK Prime Minister, 10/4/2001] Blair’s description of this hijacker as being involved in the USS Cole and African Embassy attacks strongly suggests the person he is referring to is Khalid Almihdhar. Almihdhar allegedly had a hand in the Cole attack (see Early October 2001) and had links to one of the captured embassy bombers, Mohamed al-Owhali. Before the Cole attacks, al-Owhali stayed at an al-Qaeda communications hub in Yemen run by Almihdhar’s father-in-law (see February 2001 and After). Additionally, al-Owhali met an al-Qaeda operative in Pakistan by the name of Khalid, although this may have been Khallad (aka Tawfiq bin Attash), or even Khalid Shaikh Mohammed. [United State of America v. Usama bin Laden, et al., Day 14, 3/7/2001; Guardian, 10/5/2001; CNN, 10/16/2001; Burke, 2004, pp. 174; 9/11 Commission, 7/24/2004, pp. 222; Wright, 2006, pp. 309] It is also possible that the person alluded to in Blair’s speech is Nawaf Alhazmi, who also had connections to the embassy bombings (see 1993-1999).
October 10, 2001: FBI Issues List of 22 Most Wanted Terrorists; $5 Million Reward Placed on All of Them
The FBI releases a list of its 22 most wanted terrorists. The US government offers up to $5 million for information leading to the capture of anyone of the list. The men are: Al-Qaeda leaders Osama bin Laden, who was indicted by a grand jury in 1998 (see June 8, 1998), Ayman al-Zawahiri, linked to a 1995 bombing in Pakistan (see November 19, 1995), and Mohammed Atef, who provided training to Somali fighters before the Black Hawk Down incident (see Late 1992-October 1993); Khalid Shaikh Mohammed (KSM), for his role in the 1995 Bojinka plot (see January 6, 1995). KSM is actually the mastermind of 9/11, although the US intelligence community has allegedly not yet pieced this information together (see (November 7, 2001)); Several other operatives suspected of involvement in the 1998 US embassy bombings in Africa (see 10:35-10:39 a.m., August 7, 1998): Fazul Abdullah Mohammed (see August 2, 2008), Mustafa Fadhil, Usama al-Kini (a.k.a. Fahid Muhammad Ally Msalam (see August 6-7, 1998)), Ahmed Khalfan Ghailani (see July 25-29, 2004), Sheikh Ahmed Salim Swedan (see July 11, 2002), Abdullah Ahmed Abdullah (see September 10, 2002), Anas al-Liby (see January 20, 2002- March 20, 2002), Saif al-Adel (see Spring 2002), Ahmed Mohammed Hamed Ali, and Mushin Musa Matwalli Atwah (see April 12, 2006); Abdul Rahman Yasin, a US-Iraqi involved in the 1993 World Trade Center bombing (see March 4-5,1993); Ahmed Ibrahim Al-Mughassil, Ali Saed Bin Ali El-Houri, Ibrahim Salih Mohammed Al-Yacoub, and Abdelkarim Hussein Mohamed Al-Nasser, for their alleged part in the 1996 Khobar Towers bombing in Saudi Arabia (see June 25, 1996); Imad Mugniyah, Hassan Izz-Al-Din, and Ali Atwa for the hijacking of TWA Flight 847 in June 1985. [CNN, 10/10/2001]
October 12, 2001: Additional Suspected Terrorist Supporters’ Assets Frozen
The US and Britain freeze the assets of 39 additional individuals and organizations designated by the US as connected to terrorism. $24 million is seized. The British also freeze the assets of 27 other entities named by the US in late September 2001 (see September 24, 2001). The new list includes 33 individuals and six organizations. Twenty-two of the individuals appeared on the FBI’s latest “most wanted terrorists” list. Saudi multimillionaire businessman Yassin al-Qadi is named (see October 12, 2001). So is Khalid Shaikh Mohammed, who will later be identified as the mastermind of 9/11. Five of the names were al-Qaeda leaders on a United Nations list published in March 8, 2001, with a recommendation that all nations freeze their assets. Other countries froze the assets of those on that list before 9/11, but the US did not (see March 8, 2001).

November 2001: Monitored Al-Qaeda Operative Connects KSM to 9/11 Hijackers
When investigators search the home of Amer el-Azizi, a known al-Qaeda operative, they find an e-mail address that connects him to 9/11 mastermind Khalid Shaikh Mohammed (KSM). El-Azizi helped arrange a meeting between lead hijacker Mohamed Atta and an associate, Ramzi bin al-Shibh, in the run-up to 9/11 (see July 8-19, 2001), although he was monitored by Spanish authorities at the time (see Before July 8, 2001) and arrested in Turkey in 2000 (see October 10, 2000). His arrest shortly after 9/11 will be frustrated by Spanish intelligence (see October 2001 and Shortly After November 21, 2001) and he will go on to be involved in the 2004 Madrid bombings (see Before March 11, 2004 and 7:37-7:42 a.m., March 11, 2004). An indictment released in 2004 will say, “A fundamental document… connects Amer el-Azizi directly with those responsible for the terrorist attacks of Sept. 11, 2001, and concretely with Khalid Shaikh Mohammed via the e-mail address identified as Safar86@usa.net.” The e-mail address “was being used by an individual who facilitated trips for al-Qaeda members in direct connection with [KSM], organizer of the attacks.” A detainee will also later say that el-Azizi was in contact with the 9/11 plotters via e-mail. [Los Angeles Times, 4/29/2004] After 9/11, however, when the Spanish want to indict el-Azizi, the US will be reluctant to turn the information over to them, and it will take six months to get it. Despite this, problems persist in information sharing between the US and Spain and this has an impact on prosecutions (see Mid-2002-June 1, 2006). [Wall Street Journal, 5/4/2004]
