On April 24, 1992, Houston pizza deliveryman Ahmad Ajaj and San Antonio cabdriver Ibrahim Ahmad Suleiman fly together from Texas to Pakistan. Suleiman is a Texas contact of the Al-Kifah Refugee Center, the Brooklyn-based Islamist militant organization linked to both the CIA and al-Qaeda (see 1986-1993). Suleiman had begun raising funds for the Afghan war in Texas in the late 1980s, and acquaintances said he traveled to Pakistan several times, carrying a briefcase full of cash to fund the mujaheddin fighting in Afghanistan. When they arrive in Pakistan, they stay at a hostel in Peshawar, near the Afghanistan border, known as the Abdullah Azzam House. Named after Osama bin Laden’s mentor Abdullah Azzam, this hostel is owned by Al-Kifah and also houses its Pakistan headquarters. Ajaj and Suleiman stay there off and on over the next several months. Al-Qaeda bomber Ramzi Yousef also sometimes stays there during the same months. Ajaj also allegedly receives explosives training at an Afghanistan training camp with Yousef. His letter of introduction to the camp is signed by an Azzam House official. On September 1, 1992, Ajaj and Yousef arrive together in New York City on a flight from Pakistan. Ajaj is carrying some bomb manuals; investigators will later find the fingerprints of Ajaj, Yousef, and Suleiman on them. Both men are carrying identification cards that give the PO box number in Tucson, Arizona, that matches an al-Kifah branch there. Ajaj is briefly detained at the airport, but Yousef is allowed to go. [Dallas Morning News, 6/8/1997] He gets into a taxi and tells the taxi driver to drive him to the building that houses the al-Qaeda headquarters in Brooklyn as well as the closely associated Al Farooq mosque, led at the time by the “Blind Shiekh,” Sheikh Omar Abdul-Rahman. [Lance, 2003] Ajaj and Yousef will later be sentenced to life in prison for their roles in the 1993 WTC bombing (see February 26, 1993). Suleiman will only be sentenced to 10 months in prison for lying to a grand jury about his travels with Ajaj. [New York Times, 11/25/1998] A CIA internal report will conclude the agency is “partly culpable” for the WTC bombing, mainly due to its support for Al-Kifah (see January 24, 1994).
May 1992-Spring 1993: ISI Helps Ramzi Yousef Travel, Then Helps Him Avoid Capture
Ramzi Yousef gets considerable help from the Pakistani ISI. When Yousef returns to Pakistan on May 15, 1992, he uses an Iraqi passport bearing a visa issued by the Pakistani embassy in Baghdad. However, the seal on the visa is not the official one and the signature of the visa officer is faked. A senior US intelligence official will later say, “Yousef was developing high-level contacts in Pakistani intelligence through his links with bin Laden, mainly in the ISI. It’s a dirty mess. They facilitated much of his travel. Getting airport officials to turn a blind eye to his travel would have been nothing. [Reeve, 1999, pp. 136-137] Then, on August 31, 1992, Yousef and Ahmed Ajaj are able to fly from Pakistan to the US despite lacking the proper papers to leave Pakistan. US intelligence officials will later claim senior ISI officials helped Yousef enter the US. [Reeve, 1999, pp. 139] When Ramzi Yousef’s Pakistani immigration records are checked after the WTC bombing, it is discovered his embarkation card and other documents had mysterious disappeared. ISI agents had access to the room where the records were stored. The FBI later gives the Pakistani government the names of Pakistani officials they suspect were colluding with terrorists, but apparently it is never discovered for sure who helped Yousef. One US investigator will later say, “Bin Laden had friends in the ISI who had funded him during the war in Afghanistan. The same contacts were cultivated by Yousef and members of his family.” [Reeve, 1999, pp. 48-49]
September 1, 1992: US Misses Opportunity to Stop First WTC Bombing and Discover Al-Qaeda
Al-Qaeda operatives Ahmad Ajaj and Ramzi Yousef enter the US together. Ajaj is arrested at Kennedy Airport in New York City. Yousef is not arrested and will later mastermind the 1993 bombing of the World Trade Center. “The US government was pretty sure Ajaj was a terrorist from the moment he stepped foot on US soil,” because his “suitcases were stuffed with fake passports, fake IDs, and a cheat sheet on how to lie to US immigration inspectors,” plus “two handwritten notebooks filled with bomb recipes, six bomb-making manuals, four how-to videotapes concerning weaponry, and an advanced guide to surveillance training.” However, Ajaj is charged only with passport fraud and serves a six-month sentence. From prison, Ajaj frequently calls Yousef and others involved in the 1993 WTC bombing plot, but no one will translate the calls until long after the bombing. [Los Angeles Times, 10/14/2001] Ajaj will be released from prison three days after the WTC bombing, but is later rearrested and sentenced to more than 100 years in prison. [Los Angeles Times, 10/14/2001] One of the manuals seized from Ajaj will be horribly mistranslated for the trial. For instance, the title page is said to say “The Basic Rule,” published in Jordan in 1982, when in fact the title says “al-Qaeda” (which means “the base” in English), published in Afghanistan in 1989. Investigators will subsequently complain that a proper translation could have shown an early connection between al-Qaeda and the WTC bombing. [New York Times, 1/14/2001] An Israeli newsweekly will report that the Palestinian Ajaj may have been a mole for the Israeli Mossad. The Village Voice will suggest that Ajaj may have had “advance knowledge of the World Trade Center bombing, which he shared with Mossad, and that Mossad, for whatever reason, kept the secret to itself.” Ajaj is not just knowledgeable, but is involved in the planning of the bombing from his prison cell. [Village Voice, 8/3/1993]
Around February 1993: Three WTC Bombers Travel on Saudi Passports with Indicator of Islamist Extremism, Presumably Tracked by Saudi Authorities
The 9/11 Commission, relying on a CIA report, will later say that three of the men involved in the 1993 World Trade Center bombing travel on Saudi passports containing an indicator of possible Islamist extremism. [9/11 Commission, 8/21/2004, pp. 46-47, 61 
] Author James Bamford will say that it is a “secret coded indicator, placed there by the Saudi government, warning of a possible terrorist affiliation.” [Bamford, 2008, pp. 58-59] It is unclear what the indicator looks like precisely and who the men are. However, Ahmad Ajaj, an associate of lead bomber Ramzi Yousef, does have a Saudi passport. Some of the 9/11 hijackers will later use Saudi passports with the same indicator (see October 28, 2000, June 1, 2001, and June 13, 2001, and November 2, 2007). [9/11 Commission, 8/21/2004, pp. 46-47, 61 ]
January 24, 1994: CIA Concludes It Is ‘Partly Culpable’ for WTC Bombing
The Boston Herald reports that an internal CIA report has concluded that the agency is “partially culpable” for the 1993 World Trade Center bombing (see February 26, 1993) because it helped train and support some of the bombers. One source with knowledge of the report says, “It was determined that a significant amount of blowback appeared to have occurred.” A US intelligence source claims the CIA gave at least $1 billion to forces in Afghanistan connected to Gulbuddin Hekmatyar. More than a half-dozen of the WTC bombers belonged to this faction, and some of the CIA money paid for their training. The source says, “By giving these people the funding that we did, a situation was created in which it could be safely argued that we bombed the World Trade Center.” Those connected to the bombing who went to Afghanistan include Sheikh Omar Abdul-Rahman, Clement Rodney Hampton-el, Siddig Siddig Ali, Ahmed Ajaj, and Mahmud Abouhalima. [Boston Herald, 1/24/1994] Additionally, Ramzi Yousef trained in Afghanistan near the end of the Afghan war, and there are claims he was recruited by the CIA (see Late 1980s). “Intelligence sources say the CIA used the Al-Kifah Refugee Center in Brooklyn—founded to support the Afghani rebels fighting Soviet occupation—to funnel aid to Hekmatyar, setting the stage for terrorists here to acquire the money, guns and training needed to later attack the Trade Center. CIA support also made it easier for alleged terrorist leaders to enter the country.” [Boston Herald, 1/24/1994] It will later be alleged that the CIA repeatedly blocked investigations relating to Al-Kifah, which was al-Qaeda’s operational base in the US (see Late 1980s and After).
December 16, 1994-May 1995: Osama’s Brother-in-Law Khalifa Is Arrested in US
Mohammed Jamal Khalifa, a brother-in-law to bin Laden, is arrested in the US. He is held for visa fraud, but he is believed to be a major terrorist. His arrest takes place at a Holiday Inn in Morgan Hill, California. [San Francisco Chronicle, 10/24/2001] That is only about 20 miles from Santa Clara, where double agent Ali Mohamed is running an al-Qaeda cell (see 1987-1998). Counterterrorism expert Steven Emerson will later say of Khalifa and Mohamed, “It seems to me that they were probably in contact. I’m basing that only intuitively on the fact that they were in the same area, they were close to bin Laden, and they would’ve had an incentive to stay together.” [Lance, 2006, pp. 167] According to one account, Khalifa is arrested on behalf of the government of Jordan, because he is on trial there. [San Francisco Chronicle, 10/24/2001] Another account claims that Philippine authorities “tipped off Federal authorities on Khalifa’s movements.” [Filipino Reporter, 4/27/1995] He is traveling on a Saudi passport. He’d flown into the US from London on December 1 and has papers indicating he would be heading back to the Philippines. [Lance, 2006, pp. 158-159] It has been claimed that the CIA helped him get his US visa (see December 1, 1994). There are many reasons for US authorities to suspect Khalifa is a major terrorist figure: 
He is arrested with Mohammed Loay Bayazid, one of the dozen or so original members of al-Qaeda. Bayazid had attempted to purchase nuclear material for bin Laden the year before (see December 16, 1994). Philippine investigators had recently completed a secret report on terrorist funding. The report focuses on Khalifa, and says his activities in the Philippines strongly link with Muslim extremist movements in Iraq, Jordan, Turkey, Russia, Malaysia, the United Arab Emirates, Romania, Lebanon, Syria, Pakistan, Albania, the Netherlands, and Morocco. It calls a charity which Khalifa runs a “pipeline through which funding for the local extremists is being coursed.” Perhaps not coincidentally, the report was released just one day before Khalifa’s arrest in the US (see December 15, 1994). His possessions, which are quickly examined and translated, include a handwritten manual in Arabic detailing how to set up a terrorist curriculum at a school in the Philippines, giving lessons in bomb-making and assassination. [San Francisco Chronicle, 10/24/2001] Khalifa’s business card was discovered in a search of the New York City residence of Sheikh Omar Abdul-Rahman in 1993 (see August 1993). He is an unindicted coconspirator in the “Landmarks” bombings plot, which would have killed thousands in New York City. The trial is getting underway at this time. Abdul-Rahman will be convicted and sentenced to over 300 years in prison (see June 24, 1993). A State Department cable from days after his arrest states Khalifa is a “known financier of terrorist operations and an officer of an Islamic NGO in the Philippines that is a known Hamas front.” An alias is found in his personal organizer that was also used in a bomb-making manual brought into the US by Ahmad Ajaj, Ramzi Yousef’s travel partner, when the two of them came to the US to implement the 1993 World Trade Center bombing (see September 1, 1992). Bojinka plotter Wali Khan Amin Shah’s phone number is found in Khalifa’s possessions. The Bojinka plot, if successful, also would have killed thousands (see January 6, 1995). [Lance, 2006, pp. 158-159] A number in Pakistan that Ramzi Yousef had used to call the Philippines is found as well. Author Peter Lance will later note that such numbers “should have led the FBI directly to Ramzi Yousef, the world’s most wanted man” at the time. [Lance, 2006, pp. 160]
However, despite this wealth of highly incriminating material, within weeks of his arrest the US will decide to deport him to Jordan (see January 5, 1995). Over the next four months, even more of his links to terrorist activity will be discovered (see Late December 1994-April 1995). But Khalifa will be deported anyway (see April 26-May 3, 1995), and then soon freed in Jordan (see July 19, 1995).
