A fire lasting several hours leads to the forced evacuation of the CIA headquarters in Langley, Virginia. [Reuters, 8/8/2001] The fire is discovered on August 7 at around 5:45 p.m., in the northeast section of the agency’s older headquarters building, and more than 60 firefighters are involved in putting it out. It was reportedly caused by a workman at the top of an elevator shaft dropping a welder, which ignited wood at the bottom of the shaft. Both the older headquarters building and the agency’s new headquarters building nearby are evacuated. Following this fire, A. B. “Buzzy” Krongard—the executive director of the CIA since March this year—is dismayed to find that plans for an evacuation of the headquarters are patchy, and that some of the fire alarms do not work. In the ensuing month he therefore initiates regular fire drills and equips key agency officials with tiny walkie-talkies, meaning communication will still be possible should cell phones ever go out. Krongard declares that evacuating safely is to be more important than storing classified material, and has the agency’s computer network reprogrammed so an evacuation warning could be flashed on all computer screens. Journalist and author Ronald Kessler will describe the August 7 fire as being “fortuitous,” as little over a month later, on the morning of September 11, CIA Director George Tenet will order the evacuation of the headquarters building due to fears that it might be targeted (see (9:50 a.m.-10:00 a.m.) September 11, 2001). On that day, Tenet and other top officials will reconvene at an alternate location on the CIA campus, “[f]ollowing procedures laid out by Krongard after the fire.” [Central Intelligence Agency, 3/16/2001; Associated Press, 8/7/2001; Washington Post, 8/8/2001; Kessler, 2003, pp. 222-223]
August 8-15, 2001: Israel Reportedly Warns of Major Assault on the US
At some point between these dates, Israel warns the US that an al-Qaeda attack is imminent. [Fox News, 5/17/2002] Reportedly, two high-ranking agents from the Mossad come to Washington and warn the FBI and CIA that from 50 to 200 terrorists have slipped into the US and are planning “a major assault on the United States.” They say indications point to a “large scale target,” and that Americans would be “very vulnerable.” They add there could be Iraqi connections to the al-Qaeda attack. [Daily Telegraph, 9/16/2001; Ottawa Citizen, 9/17/2001; Los Angeles Times, 9/20/2001] The Los Angeles Times later retracts its story after a CIA spokesperson says, “There was no such warning. Allegations that there was are complete and utter nonsense.” [Los Angeles Times, 9/21/2001] Other newspapers do not retract it.
August 15, 2001: CIA Told of Moussaoui’s Forthcoming Arrest, Searches for Information
The FBI’s Minneapolis field office tells the CIA that Zacarias Moussaoui will be arrested the next day (see August 16, 2001). The information is communicated to a CIA field office, which then informs the Counterterrorist Center (CTC) at CIA headquarters. The CTC searches for information on Moussaoui, but does not find anything. The CIA has information on Moussaoui at this point, but the information is related to one of Moussaoui’s aliases and the CIA apparently does not understand that the alias is used by Moussaoui (see April 2001). [Tenet, 2007, pp. 200-201]
August 15-September 10, 2001: Possible 9/11 Hijacker Accomplices Behave Suspiciously in US
Three Qatari men—Meshal Al Hajri, Fhad Abdulla, and Ali Al Fehaid—behave curiously in the weeks before 9/11, leading to later suspicions that they could have had some link to the 9/11 attacks.
Suspicious Behavior – The men fly from London to New York on August 15, 2001, and travel around the East Coast together. They visit the World Trade Center, the Statue of Liberty, the White House, and various parts of Virginia, but it is unclear if they are simply tourists or are conducting surveillance on potential targets. On August 24, they fly from Washington to Los Angeles and check into a single room at a hotel near the airport. They pay with cash and are booked to leave on September 10, which they do. They spend about a week traveling within California with a United Arab Emirates man named Mohamed Al Mansoori. The hotel staff grow suspicious of the men because they notice pilot uniforms, laptops, and cardboard boxes addressed to Syria, Afghanistan, and Jordan in their room. This may not be that unusual, since pilots frequently stay at the hotel due to its proximity to the airport. But, according to a later US government document, the men also “had a smashed cellular phone in the room and a cellular phone attached by wire to a computer. The room also contained pin feed computer paper print outs with headers listing pilot names, airlines, flight numbers, and flight times.” Suspicions are further aroused because on the last few days of their stay, the men request that their room should not be cleaned. The staff are not alarmed enough to alert police, however. The men are scheduled to board American Airlines Flight 144 on September 10, from Los Angeles to Washington. This flight will be reassigned Flight 77 the next day and will crash into the Pentagon in the 9/11 attacks. However, the men do not take the flight, but instead fly directly from Los Angeles to London on a British Airways flight the same day, and then back to Doha, Qatar. [Daily Telegraph, 2/1/2011]
Link to ‘Convicted Terrorist’? – In 2010, the names of the three men and Mansoori will appear in a State Department cable suggesting that they are still being investigated for a possible role in the 9/11 attacks (see February 11, 2010). The cable will state, “A subsequent FBI investigation revealed that the men’s plane tickets were paid for and their hotel reservations in Los Angeles, CA, were made by a convicted terrorist.” This is likely a reference to Fahed Alhajri, a Qatari who lived in Chesapeake, Virginia. News reports in 2002 will call Alhajri a suspected terrorist because of some items found in his possession when he is arrested as part of a visa fraud scheme that same year. For instance, he has photos of Osama bin Laden and the World Trade Center in his apartment, as well as a datebook with only one entry, written on 9/11 with the cryptic words, “Trackd the World Trade Center or the Pentagon Trackd for the Plane.” According to these news reports, he paid for the Los Angeles hotel room and plane fare of his brother Meshal Alhajri and two friends. Alhajri is one of the three Qatari men, and the friends presumably are the other two. But Fahed Alhajri cannot be called a “convicted terrorist,” because in 2003 he is convicted of visa fraud, not terrorism, and then he is deported. [New York Times, 5/10/2002; MSNBC, 2/2/2011]
Terrorists or Tourists? – The names of the three men will be included on an FBI list of over 300 people wanted for questioning in connection with the 9/11 attacks that is accidentally made public in late 2001 (see October 3, 2001). However, they never are questioned by the FBI, apparently because they left the US the day before 9/11 and never came back. Mansoori’s name is not on that list, but he will remain in the US, and he will be questioned by the FBI as part of a years-long investigation into his activities. The FBI will never come up with enough evidence to charge him, but he will be deported several years after 9/11. One US official will say, “I don’t think people were in love with him,” implying the FBI continued to have suspicions about him. In 2011, the 2010 cable mentioning the men will be made public, and The Telegraph will write: “It is not known whether the FBI believe that the men were simply assisting the hijackers or were a fifth cell who pulled out at the final moment. Alternatively, they may have been planning an attack on the West Coast of America or even London which was abandoned or went wrong.” But there is also the possibility they may simply have been tourists.

August 16, 2001: Roommate Interview Strengthens Case against Moussaoui
Hours after Zacarias Moussaoui is taken into custody in Minnesota, his friend and roommate Hussein al-Attas is interviewed by the FBI. The two men had recently driven together to Minnesota from Oklahoma (see August 10-11, 2001). 
According to a summary of the interview written at the time, “Al-Attas indicated that Moussaoui believes that it is acceptable to kill civilians who harm Muslims and that he approves of martyrs.” Al-Attas says Moussaoui talked about holy war every day when they roomed together. When asked if he had ever heard Moussaoui make a plan to kill those who harm Muslims, “Al-Attas admit[s] that he may have heard him do so, but that because it is not in [al-Attas’] own heart to carry out acts of this nature, he claimed that he kept himself from actually hearing and understanding.” Al-Attas says Moussaoui holds strong anti-American views and might be willing to act on his beliefs. Al-Attas describes Moussaoui as so secretive that he refuses to give his full name, identifying himself only as “Shaqil.” He also says that Moussaoui told him “true” Muslims must prepare themselves to fight and they should understand the suffering of Muslims in places like Palestine and Kosovo. He mentions that he and Moussaoui are carrying fighting gloves and shin guards to practice martial arts as part of Moussaoui’s philosophy that Muslims should be ready to fight nonbelievers. He has not heard Moussaoui mention any specific terrorist plot, but says that Moussaoui “is suspicious to me, too.”
FBI agents interview al-Attas again the following day, then charge him with violating the terms of his student visa by working at a mosque in Oklahoma, and arrest him. During the second interview, al-Attas says that Moussaoui follows the teachings of a sheikh whose name he would not disclose to him (see August 17, 2001). The agents contact FBI supervisors in Washington to seek approval to get a warrant to search Moussaoui’s computer. The supervisors are aware of what al-Attas said in the interview, but nevertheless they tell the Minnesota FBI agents that they do not want to attempt to get the warrant because it has not been shown that Moussaoui is an agent of a foreign power. The New York Times will note that the content of al-Attas’ interview “raise[s] new questions about whether top [FBI] officials… were aggressive enough in responding to that information.” [Washington Post, 1/31/2002; New York Times, 5/24/2002; Associated Press, 3/21/2006] Al-Attas will be arrested shortly after 9/11 and held as a material witness. He will later plead guilty to lying about Moussaoui. He lied in claiming that he did not know Moussaoui’s real name, lied about plans to go with Moussaoui to New York City in late August 2001, lied about Moussaoui’s desire to participate in holy war, and lied about a planned trip to speak to religious scholars who would encourage al-Attas to participate in holy war. He will be sentenced to time served, but will be kept imprisoned until the conclusion of Moussaoui’s trial in 2006 (see March 6-May 4, 2006). [Canadian Broadcasting Corporation, 7/22/2002; Associated Press, 10/22/2002] It is also later revealed that Moussaoui had recently convinced al-Attas to fight in Chechnya in order to prepare for holy war. [Wall Street Journal, 2/4/2002] Furthermore, the person who attempts to post bond for al-Attas had been the subject of a full-field FBI international terrorism investigation in Oklahoma. This unnamed person was a recruiter for a radical Palestinian group and a member of the Muslim Brotherhood. [US Congress, 7/24/2003] In post-9/11 media accounts, al-Attas is generally portrayed as someone who had been innocently and accidentally caught up with Moussaoui. But it appears that in the weeks before 9/11, US intelligence will consider the possibility that al-Attas may have been plotting with Moussaoui. For instance, a CIA cable that will be sent on August 24 is titled “Subjects Involved in Suspicious 747 Flight Training,” (see August 24, 2001) one that will be sent on August 28 has Moussaoui and al-Attas’ names as the title.

August 18, 2001 or Shortly Before: Minneapolis FBI Contacts CIA Headquarters for Help with Moussaoui Case
Minneapolis FBI agent Harry Samit contacts Charles Frahm, an FBI agent who is working with the CIA’s bin Laden unit as a deputy chief, to discuss the Moussaoui case. Frahm passes on information to other CIA officers. Frahm will also be contacted by FBI headquarters about the case (see (August 20, 2001)) and will provide information linking the Chechen rebels, to which Moussaoui is connected, to Osama bin Laden and al-Qaeda (see August 24, 2001). [Tenet, 2007, pp. 201]
Before August 22, 2001: Threat Information about ‘Khalid’ Increases Interest in 9/11 Hijacker Almihdhar
The CIA receives some threat information about a man named “Khalid” and begins to examine data on everybody it knows whose first name is “Khalid”. In an August 22 e-mail FBI agent Dina Corsi writes that this is one of the reasons for the interest in hijacker Khalid Almihdhar at this time: “the reason [the intelligence community] were looking at [Almihdhar] is relatively general—basically they were looking at all individuals using the name Khalid because of some threat information.” [US Department of Justice, 11/2004, pp. 285 
] The identity of the man named Khalid they are looking for is not revealed, however, there is threat reporting starting in June 2001 concerning someone an informant called Khalid, who is later revealed to be Khalid Shaikh Mohammed (see June 12, 2001).
August 20, 2001: FBI Headquarters Opens Informal Communication Channel with CIA over Moussaoui
After the Zacarias Moussaoui case (see August 16, 2001) is transferred from the Iran unit to the Radical Fundamentalist Unit (RFU) at FBI headquarters (see August 20-September 11, 2001), RFU chief Dave Frasca contacts Charles Frahm, an FBI manager detailed to the CIA with responsibility for Alec Station, the CIA’s bin Laden unit. According to Frahm, who has already been contacted by the FBI Minneapolis field office (see August 18, 2001 or Shortly Before), Frasca asks CIA headquarters to quickly share any information it has on Moussaoui with the FBI, but does not send the agency a formal request, even though FBI headquarters continues to coordinate the case with the CIA. In an e-mail sent around August 28, Frahm will indicate that the CIA has still not received a formal request from the bureau. [US Department of Justice, 11/2004, pp. 123, 154-5, 231-2 ; Wright, 2006, pp. 313] The CIA will tell FBI agent Harry Samit that it thinks there is enough information to firmly link Moussaoui to a terrorist group (see August 24, 2001).
August 21, 2001-September 13, 2001: FBI and CIA Ask British about Moussaoui But Get No Answer until After 9/11
On August 21, the FBI’s legal attache in London hand-delivers a request for information about Zacarias Moussaoui to British officials. On August 24, the CIA tells the British that Moussaoui is a possible “suicide hijacker” who is involved in “suspicious 747 flight training.” The CIA asks for information on him on August 28. The FBI raises the matter with the British again on September 3 and again on September 5. Although the British do not respond to these requests until just after 9/11, French intelligence, which has been sharing information about Moussaoui with the British (see 1999), sends the FBI some information about Moussaoui’s activities and history in England (see August 22, 2001). Then, on September 13, 2001, the British supposedly learn new information that Moussaoui attended an al-Qaeda training camp in Afghanistan (see 1995-1998). The 9/11 Commission will conclude, “Had this information been available in late August 2001, the Moussaoui case would almost certainly have received intense and much higher-level attention.” A British official will complain, “We passed on all the relevant information [about Moussaoui] as soon as we obtained it.” [Guardian, 4/14/2004; 9/11 Commission, 7/24/2004, pp. 274-75] However, the British had Moussaoui under surveillance in 2000 (see Mid-2000-December 9, 2000), and appear to have failed to pass on any information about this surveillance or what it uncovered.
August 21-22, 2001: FBI Agents Finally Realize 9/11 Hijacker Almihdhar Is in US
An FBI agent detailed to the CIA’s bin Laden unit locates CIA cables saying that future 9/11 hijacker Nawaf Alhazmi entered the US in early 2000. The agent, Margaret Gillespie, then checks with the US Customs Service and discovers that another future 9/11 hijacker, Khalid Almihdhar, entered the US on July 4, 2001, and there is no record he has left the country. As there is “an imperative to find anyone affiliated with al-Qaeda if they [are] believed to be in the US,” Gillespie immediately contacts Dina Corsi, an FBI agent in its bin Laden unit. Gillespie, who has been examining the USS Cole bombing and al-Qaeda’s Malaysia summit for some time, will later say that when she learns of their arrival in the US, “it all clicks for me.” The Justice Department’s office of inspector general will find that Gillespie’s “actions on receipt of the information clearly indicate that she understood the significance of this information when she received it. She took immediate steps to open an intelligence investigation.” Gillespie and Corsi meet with Tom Wilshire, a CIA officer involved in the investigation (see August 22, 2001), and Almihdhar and Alhazmi are soon watchlisted (see August 23, 2001).
