A son of Sheikh Omar Abdul-Rahman, the al-Qaeda leader convicted in 1995 of conspiring to blow up tunnels and other New York City landmarks, is heard to say that the best way to free his father from a US prison might be to hijack an American plane and exchange the hostages. This will be mentioned in President Bush’s August 2001 briefing titled “Bin Laden Determined to Strike in US” (see August 6, 2001). [Washington Post, 5/18/2002] It may be the warning was discovered by reporters at bin Laden’s press conference this month, since two of Abdul-Rahman’s sons are there and speak in belligerent tones (see May 26, 1998 and May 1998). A similar warning will be discovered in May 2001, but will not be mentioned in Bush’s briefing (see May 23, 2001).
May 26, 1998: Bin Laden Promises to Bring Jihad to US
Bin Laden discusses “bringing the war home to America,” in a press conference from Khost, Afghanistan. [US Congress, 9/18/2002] Bin Laden holds his first and only press conference to help publicize the fatwa he published several months before. Referring to the group that signed the fatwa, he says, “By God’s grace, we have formed with many other Islamic groups and organizations in the Islamic world a front called the International Islamic Front to do jihad against the crusaders and Jews.” He adds later, “And by God’s grace, the men… are going to have a successful result in killing Americans and getting rid of them.” [CNN, 8/20/2002] He also indicates the results of his jihad will be “visible” within weeks. [US Congress, 7/24/2003] Two US embassies will be bombed in August (see 10:35-10:39 a.m., August 7, 1998). Bin Laden sits next to Ayman al-Zawahiri and Mohammed Atef during the press conference. Two Pakistani journalists and one Chinese journalist attends. But event never gets wide exposure because no independent videotaping is allowed (however, in 2002 CNN will obtain video footage of the press conference seized after the US conquered Afghanistan in late 2001). Pakistani journalist Ismail Khan attends and will later recall, “We were given a few instructions, you know, on how to photograph and only take a picture of Osama and the two leaders who were going to sit close by him. Nobody else.” Two sons of Sheikh Omar Abdul-Rahman attend and distribute what they claim is the will or fatwa of their father (see May 1998), who has been sentenced to life in prison in the US. Journalist Peter Bergen will later comment that the significance of the sons’ presence at the press conference “can’t be underestimated” because it allows bin Laden to benefit from Abdul-Rahman’s high reputation amongst radical militants. Bergen also later says the press conference is a pivotal moment for al-Qaeda. “They’re going public. They’re saying, ‘We’re having this war against the United States.’” [CNN, 8/20/2002] The specific comment by bin Laden about “bringing the war home to America” will be mentioned in the August 2001 memo given to President Bush entitled “Bin Laden Determined to Strike in US” (see August 6, 2001).
October-November 1998: Al-Qaeda US-based Recruiting Efforts Uncovered
US intelligence learns al-Qaeda is trying to establish a cell within the US. There are indications that the organization might be trying to recruit US citizens. This apparently will be mentioned in President Bush’s August 6, 2001 briefing, which states, “A clandestine source said in 1998 that a bin Laden cell in New York was recruiting Muslim-American youth for attacks” (see August 6, 2001). In the next month, there is information that a terror cell in the United Arab Emirates is attempting to recruit a group of five to seven young men from the US to travel to the Middle East for training. This is part of a plan to strike a US domestic target. [US Congress, 9/18/2002; US Congress, 7/24/2003]
December 1, 1998: Bin Laden Actively Planning Attacks Inside US
According to a US intelligence assessment, “[bin Laden] is actively planning against US targets and already may have positioned operatives for at least one operation.… Multiple reports indicate [he] is keenly interested in striking the US on its own soil… Al-Qaeda is recruiting operatives for attacks in the US but has not yet identified potential targets.” Later in the month, a classified document prepared by the CIA and signed by President Clinton states: “The intelligence community has strong indications that bin Laden intends to conduct or sponsor attacks inside the US.” [US Congress, 9/18/2002; Washington Post, 9/19/2002; US Congress, 7/24/2003 
; US Congress, 7/24/2003] This warning will be mentioned in the August 2001 memo given to President Bush entitled “Bin Laden Determined to Strike in US” (see August 6, 2001).
December 4, 1998: Clinton Warned ‘Bin Laden Preparing to Hijack US Aircraft’ Inside US
On December 4, 1998, an item in President Clinton’s Presidential Daily Briefing (PDB) is titled, “Bin Laden Preparing to Hijack US Aircraft and Other Attacks.” The PDB says “Bin Laden and is allies are preparing for attacks in the US, including an aircraft hijacking to obtain the release of Sheikh Omar Abdul-Rahman, Ramzi Yousef, and Muhammad Sadiq ‘Awda. One source quoted a senior member of Al-Gama’a al-Islamiyya (IG) saying that, as of late October, the IG had completed planning for an operation in the US on behalf of bin Laden, but that the operation was on hold. A senior bin Laden operative from Saudi Arabia was to visit IG counterparts in the US soon thereafter to discuss options-perhaps including an aircraft hijacking.” The same source says bin Laden may implement plans to hijack US aircraft before the start of the Muslim holy month of Ramadan on December 20 and that two members of the operational team had evaded security checks in a recent trial run at a New York airport. A possible different source says that in late September, Mohammed Shawqui Islambouli, brother of the assassin of Egyptian President Anwar Sadat and described in the PDB as an IG leader, was planning to hijack a US airliner during the “next couple of weeks” to free Abdul-Rahman and other prisoners. The PDB also says that “some members of the bin Laden network have received hijack training, according to various sources, but no group directly tied to bin Laden’s al-Qaeda organization has ever carried out an aircraft hijacking. Bin Laden could be weighing other types of operations against US aircraft.” The PDB mentions other bin Laden related threats, including recent reports that the IG has obtained surface-to-air missiles and intends to move them from Yemen to Saudi Arabia to shoot down aircraft. [Washington Post, 7/18/2004; 9/11 Commission, 7/24/2004, pp. 128-130] The private intelligence group Stratfor will later say that, in addition to his ties with IG, Islambouli worked with bin Laden in the Maktab al-Khidamat charity front in Pakistan and is believed to have lived in Afghanistan in the 1990s as “part of the group of key Egyptian advisers surrounding bin Laden.” Islambouli will formally join with al-Qaeda in 2006. [Stratfor, 8/10/2006] In early 1998, the CIA ignored information from a recently retired CIA agent that claimed 9/11 mastermind Khalid Shaikh Mohammed was in a terrorist cell with Islambouli, both were experts on plane hijackings, and were planning to hijack planes (see Early 1998). Perhaps not coincidentally, on this same day, CIA Director George Tenet issues a “declaration of war” against al-Qaeda in a memo to the US intelligence community (see December 4, 1998). Also on this day, counterterrorism “tsar” Richard Clarke holds a meeting of his interagency Counterterrorism and Security Group (CSG) to discuss the threat. The group agrees that New York City airports should go on a maximum security alert that weekend and security should be boosted at other East Coast airports. The FBI, FAA, and New York City Police Department get versions of the PDB report. Later in December and again in January 1999 the source says the hijacking has been postponed because two operatives have been arrested in Washington or New York. But the FBI is unable to find any information to support the threat nor is it able to verify any arrests similar to what the source described, and the source remains mysterious. The high alert in New York airports is canceled by the end of January. [9/11 Commission, 7/24/2004, pp. 128-130] This PDB will be mentioned in President Bush’s famous August 6, 2001 PDB, but mentions that US officials “have not been able to corroborate” the plot (see August 6, 2001).
January 20-September 10, 2001: President Bush Briefed on Al-Qaeda over 40 Times
National Security Adviser Condoleezza Rice later testifies to the 9/11 Commission that in the first eight months of Bush’s presidency before 9/11, “the president receive[s] at these [Presidential Daily Briefings] more than 40 briefing items on al-Qaeda, and 13 of those [are] in response to questions he or his top advisers posed.” [Washington Post, 4/8/2004] The content of the warnings in these briefings are unknown. However, CIA Director George Tenet claims that none of the warnings specifically indicates terrorists plan to fly hijacked commercial aircraft into buildings in the US. [New York Times, 4/4/2004] Counterterrorism “tsar” Richard Clarke will later emphasize, “Tenet on 40 occasions in… morning meetings mentioned al-Qaeda to the president. Forty times, many of them in a very alarmed way, about a pending attack.” [Vanity Fair, 11/2004] These briefings are normally given in person by CIA Director George Tenet, and are usually attended by Vice President Cheney and National Security Adviser Rice. In the Clinton administration, up to 25 officials recieved the PDB. But in the Bush adminisration before 9/11, this was sharply reduced to only six people (see After January 20, 2001). Other top officials have to make due with an Senior Executive Intelligence Brief generally released one day later, which is similar to the PDB but often contains less information (see August 7, 2001). [9/11 Commission, 7/24/2004, pp. 256, 533]
May 16-17, 2001: US Warned Bin Laden Supporters Are Inside US and Planning an Attack
On May 16, an anonymous person calls the US embassy in the United Arab Emirates and warns that bin Laden supporters have been in the US and are planning an attack in the US using “high explosives.” The caller mentions that operatives are infiltrating the US from Canada, but there is no mention of when or where the attack might occur. The next day, based on this warning, the first item on the agenda for counterterrorism “tsar” Richard Clarke’s interagency Counterterrorism Security Group (CSG) is entitled: “[Osama bin Laden]: Operation Planned in US.” The anonymous caller’s tip cannot be later corroborated. In July, the CIA will share the warning with the FBI, the INS, the US Customs Service, and the State Department. It will also be mentioned in the August 6, 2001 Presidential Daily Briefing given to President Bush (see August 6, 2001) and Bush will be told that the CIA and FBI are investigating it. But eventually, neither the CIA nor FBI is able to corraborate the information in the call. [US Congress, 9/18/2002; Washington Post, 9/19/2002; 9/11 Commission, 7/24/2004, pp. 255, 262, 535] There are some other possibly interlinked warnings this month also warning of an al-Qaeda plot to attack the US from Canada using explosives (see May 30, 2001, May 2001, and May 2001).
May 30, 2001: FBI Is Warned of Major Al-Qaeda Operation in the US Involving Hijackings, Explosives, and/or New York City
Ahmed Ressam is convicted in the spring of 2001 for attempting to bomb the Los Angeles International Airport (see December 14, 1999). Facing the likelihood of life in prison, he starts cooperating with authorities in an attempt to reduce his sentence. On this day, he details his experiences in al-Qaeda training camps and his many dealings with top al-Qaeda deputy Abu Zubaida. According to FBI notes from Ressam’s interrogation, Zubaida asked Ressam to send him six original Canadian passports to help Zubaida “get people to America” (see May 2001 and May 2001). Zubaida “wanted an operation in the US” and talked about the need to get explosives into the US for this operation, but Ressam makes it clear this was a separate plot from the one he was involved with. Notes from this day further explain that Ressam doesn’t know if any explosives made it into the US because once an operation is initiated, operators are not supposed to talk about it to anyone. [Calgary Herald, 4/3/2002; Newsweek, 4/28/2005] Zubaida told this to Ressam in 1999, but also indicated that he is willing to wait a year or more to make sure the plot comes to fruition successfully. [Tenet, 2007, pp. 146]
Similarity to 9/11 Attacks – There’s no concrete evidence that Ressam knows any detail of the 9/11 attacks. [Newsweek, 4/28/2005] However, Fox News will later report that roughly around this time Ressam testifies “that attack plans, including hijackings and attacks on New York City targets, [are] ongoing.” [Fox News, 5/17/2002] Questioned shortly after 9/11, Ressam will point out that given what he’s already told his US interrogators, the 9/11 attacks should not be surprising. He notes that he’d described how Zubaida talked “generally of big operations in [the] US with big impact, needing great preparation, great perseverance, and willingness to die.” Ressam had told of “plans to get people hired at airports, of blowing up airports, and airplanes.” [Newsweek, 4/28/2005]
Sharing the Warning – The CIA learns of this warning in June. [Tenet, 2007, pp. 146] Ressam will repeat some of this in a public trial in July (see July 8, 2001). Apparently, the FBI also waits until July to share the information from this debriefing with most other intelligence agencies, the INS, Customs Service, and the State Department. Ressam’s warnings will first be mentioned to Bush in his now famous August 6, 2001 briefing (see August 6, 2001), but as Newsweek will note, “The information from Ressam that was contained in [Bush’s] PDB [is] watered down and seem[s] far more bland than what the Algerian terrorist was actually telling the FBI.” Zubaida’s second plot will be boiled down to one sentence in the PDB: “Ressam also said that in 1998 Abu Zubaida was planning his own US attack.” [Newsweek, 4/28/2005]
May 30, 2001: Yemenis Are Caught Taking Suspicious New York Photos
Two Yemeni men are detained after guards see them taking photos at 26 Federal Plaza in New York City. They are questioned by INS agents and let go. A few days later, their confiscated film is developed, showing photos of security checkpoints, police posts, and surveillance cameras of federal buildings, including the FBI’s counterterrorism office. The two men are later interviewed by the FBI and determined not to be a threat. However, they had taken the pictures on behalf of a third person said to be living in Indiana. By the time the FBI looks for him, he has fled the country and his documentation is found to be based on a false alias. In 2004, the identity of the third man reportedly still will be unknown. The famous briefing given to President George W. Bush on August 6, 2001 (see August 6, 2001), will mention the incident, warning that the FBI is investigating “suspicious activity in this country consistent with the preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York.” When Bush’s August 6 briefing will be released in 2004, a White House fact sheet will fail to mention the still missing third man. [New York Post, 7/1/2001; New York Post, 9/16/2001; Washington Post, 5/16/2004] In 2004, it will be reported that Dhiren Barot (a.k.a. Issa al-Hindi or Issa al-Britani), an alleged al-Qaeda operative in British custody, was sent to the US in early 2001 by Khalid Shaikh Mohammed to case potential targets in New York City. He headed a three-man team that surveyed the New York Stock Exchange and other buildings. While there are obvious similarities between the two Yemeni man with an unknown boss and Barot with two helpers, it is not known if the two cases are related. [New York Times, 8/7/2004]
July 5, 2001: President Bush Asks for Reports on Domestic Terror Threats
In 2002, Newsweek will report: “The White House acknowledged for the first time, [President] Bush was privately beginning to worry about the stream of terror warnings he was hearing that summer, most of them aimed at US targets abroad. On July 5, five days before the Phoenix memo (see July 10, 2001), Bush directed [Condoleezza] Rice to figure out what was going on domestically.” [Newsweek, 5/27/2002] In 2004, President Bush will explain why he requested this: “[T]he reason I did is because there had been a lot of threat intelligence from overseas. And part of it had to do with the Genoa [Italy] G8 conference that I was going to attend.” [US President, 4/19/2004] Though he does not mention it, the chief security concern at the late July 2001 conference he mentions is intelligence that al-Qaeda plans to fly an airplane into the conference. This threat is so widely reported before the conference (with some reports before July 5 (see June 13, 2001 and Mid-July 2001) that the attack is called off (see July 20-22, 2001). For instance, in late June, Time magazine mentioned a German intelligence report of an Osama bin Laden plot “to fly remote-controlled model aircraft packed with Semtex into the conference hall and blow the leaders of the industrialized world to smithereens”
(see June 20, 2001). Bush will later claim that this request is specifically for the later-famous August 6, 2001 briefing entitled, “Bin Laden Determined to Strike in US” (see August 6, 2001), although the CIA analysts who draft it will deny this (see July 13, 2004). [US President, 4/19/2004]
