The Al-Kifah Refugee Center is bin Laden’s largest fundraising group in the US and has offices in many cities (see 1986-1993 and 1985-1989). Counterterrorism expert Steven Emerson will later call it “al-Qaeda’s operational headquarters in the United States.” [Emerson, 2006, pp. 436] Nearly every figure involved in the 1993 WTC bombing has a connection to the Al-Kifah branch in Brooklyn, New York. [Newsweek, 3/29/1993] Bob Blitzer, a former FBI terrorism chief who heads the FBI’s first Islamic terrorism squad, is stunned to discover the number of militants connected to Al-Kifah who have left the US to fight for Muslim causes overseas. He will later remember thinking, “What the hell’s going on?” Neil Herman, head of the FBI’s WTC bombing investigation, will comment, “It was like a modern underground railroad.” But no effort is made to keep track of who has gone overseas to fight, even though many of the WTC bombers had gone overseas to fight then came back to use their training to plan an attack in the US. Furthermore, the Al-Kifah office in Brooklyn shuts itself down, but all the other branch offices remain open. US News and World Report will later note that the offices “were left largely intact [and] helped form the nucleus of bin Laden’s al-Qaeda network.” Herman will say, “They certainly continued on, but were somewhat fragmented.” Over time, the other branches generally go underground. Soon their functions are largely replaced by a network of Islamic charities. For instance, the functions of the Brooklyn branch, including its newsletter and website, are directly taken over by a new Boston-based charity called Care International (see April 1993-Mid-2003). Another charity is the Benevolence International Foundation (BIF), run by Enaam Arnaout, who is a veteran of the Al-Kifah Brooklyn office. [US News and World Report, 6/2/2002] The US will not freeze the assets of Al-Kifah until shortly after 9/11, long after all the US branches have dissolved (see September 24, 2001). There is evidence to suggest that the CIA had ties to Al-Kifah and blocked FBI investigations of it (see Late 1980s and After).
Shortly After February 26, 1993: Security Chief Predicts Terrorists Crashing a Plane into the WTC
Rick Rescorla, a security chief for a company at the World Trade Center, and his friend Dan Hill conduct an analysis of the security measures at the WTC and conclude that terrorists will likely attack the Twin Towers again, probably by crashing a plane into them. Rescorla, who has served in the US Army and worked for British military intelligence, is now the director of security at brokerage firm Dean Witter. His office is on the 44th floor of the WTC’s South Tower. [Washington Post, 10/28/2001; Stewart, 2002, pp. 193-194; New Yorker, 2/11/2002] After the WTC is bombed in February 1993 (see February 26, 1993), Rescorla calls Hill to New York to be his security consultant and assess the situation. [Stewart, 2002, pp. 191; Steve Humphries, 9/11/2005] Hill is a former Army Ranger and has had training in counterterrorism. [New Yorker, 2/11/2002; St. Augustine Record, 8/14/2011]
Anti-American Hostility Found at Mosques – Hill and Rescorla suspect that the WTC bombing was committed by Muslims. Rescorla suggests that Hill, who is himself a Muslim and speaks Arabic, try to gather some intelligence. Hill therefore lets his beard grow and visits several mosques in New Jersey. He gets into conversations with people at the mosques, expressing pro-Islamic opinions and taking an anti-American line. According to journalist and author James B. Stewart: “[A]t every other location, Hill was struck by the intense anti-American hostility he encountered. Though these were not his own views, he barely had to mention that he thought American policy toward Israel and the Middle East was misguided, or that Jews wielded too much political power, to unleash a torrent of anti-American, anti-Semitic rhetoric. Many applauded the bombing of the World Trade Center, lamenting that it hadn’t done more damage.” Referring to his experiences at the mosques, Hill tells Rescorla, “We’ve got a problem.” He also believes that, as the symbolic “tower of the Jews,” the WTC is likely to remain a target for terrorists. [Stewart, 2002, pp. 192-193; New Yorker, 2/11/2002]
Rescorla Thinks Terrorists Will Use a Different Method of Attack – Rescorla thinks that since terrorists failed to bring the Twin Towers down with a truck bomb, they may in future try a different method of attack, such as using a small, portable nuclear weapon or flying a plane into the building. He phones his friend Fred McBee and asks him to examine the possibility of an air attack on the WTC. By using a flight simulator on his computer, McBee concludes that such an attack seems “very viable” (see Shortly After February 26, 1993). [Stewart, 2002, pp. 193; Steve Humphries, 9/11/2005]
Report Warns of Another Attack on the WTC – Hill and Rescorla write a report incorporating their findings and analysis. The report warns that the WTC will likely remain a target for anti-American militants. It notes that Muslim terrorists are showing increasing tactical and technological awareness, and that the numerous young Muslims living in the United States constitute a potential “enemy within.” Rescorla states that terrorists will not rest until they have succeeded in bringing down the Twin Towers.
Hill and Rescorla Suggest Terrorists Flying a Plane into the WTC – Rescorla and Hill also lay out what they think the next terrorist attack could look like. According to Stewart, it would involve “an air attack on the Twin Towers, probably a cargo plane traveling from the Middle East or Europe to Kennedy or Newark Airport, loaded with explosives, chemical or biological weapons, or even a small nuclear weapon. Besides New York, other cities might be targeted, such as Washington or Philadelphia. Perhaps terrorists would attack all three.” Rescorla and Hill’s report concludes that Rescorla’s company, Dean Witter, should leave the WTC and move to somewhere safer in New Jersey. However, Dean Witter’s lease does not expire until 2006, and so the company will remain at the WTC. But Rescorla will start conducting regular evacuation drills for all its employees in the South Tower. [Stewart, 2002, pp. 193-194; New Yorker, 2/11/2002] Rescorla will be in his office at the WTC on 9/11. He will personally escort his company’s employees out of the South Tower, but die himself when the tower collapses. [Washington Post, 10/28/2001; BBC, 2/10/2003]
After February 26, 1993: Threat Assessments Predict Possibility of Terrorists Crashing Plane into WTC
Following the 1993 World Trade Center bombing (see February 26, 1993), the New York Port Authority asks investigative and security consulting firm Kroll Associates to help design new security measures for the WTC. Kroll’s Deputy Chairman Brian Michael Jenkins leads the analysis of future terrorist threats and how they might be addressed. Assessments conclude that a second terrorist attack against the WTC is probable. Although it is considered unlikely, the possibility of terrorists deliberately flying a plane into the WTC towers is included in the range of possible threats.

Spring 1993: Second Group of US Militants Linked to Al-Kifah Charity Front Fight in Bosnia
In June 1993, Abu Ubaidah Yahya will tell the New York Times that early in the year he went to Bosnia with several other Muslims from the New York region to help embattled Bosnian Muslims “with technical advice and medical aid.” [New York Times, 6/26/1993] Yahya is an ex-US Marine connected to numerous figures in the 1993 WTC bombing and “Landmarks” bombing plots, and US intelligence had him under surveillance since January 1993 (see January 7-13, 1993), although how intensive the surveillance was is unknown. The FBI is aware that Yahya repeatedly travels in the spring of 1993 to Vienna, Austria, to pick up money from the Bosnian-linked Third World Relief Agency charity front (see Early April 1993), so presumably he goes to nearby Bosnia on some or all of those trips. It is likely he and his group actually go to Bosnia to fight, since one of his associates told an FBI informant that Yahya and a group of about ten men he trained were going to fight in Bosnia once their training session was over, and the training ended in February 1993 (see December 1992-Early February 1993). Saudis also gave Yahya’s close associate Clement Rodney Hampton-El a considerable amount of money to train militants in the US to fight in Bosnia (see December 1992). [Miller, Stone, and Mitchell, 2002, pp. 113] Yahya is the security chief of the Al-Kifah Refugee Center, a charity front linked to both al-Qaeda and the CIA (see 1986-1993). A group of US militants linked to Al-Kifah go fight in Bosnia starting in December 1992, but this must be a different group since Yahya is still training his group for another two months (see December 1992-June 1993 and December 1992-Early February 1993).
Spring 1993: US Intelligence Connects Ramzi Yousef and Bin Laden
US intelligence learns of ties between Ramzi Yousef and bin Laden. FBI official Neil Herman, head of the WTC bombing investigation, will later say, “The first connection with bin Laden came in connection with some phone records overseas, connecting either Yousef or possibly one of his family members.” But Herman adds that bin Laden was just “one of thousands of leads that we were trying to run out.” Bin Laden will later praise Yousef but say, “Unfortunately, I did not know him before the incident.” [Reeve, 1999, pp. 47-48]
Spring 1993: US Discovers that Ramzi Yousef and KSM Have Ties with ISI
US agents uncover photographs showing Khalid Shaikh Mohammed (KSM) has ties with the Pakistani ISI. Several weeks after the World Trade Center bombing (see February 26, 1993), US agents come to Pakistan to search for Ramzi Yousef for his part in that bombing. Searching the house of Zahid Shaikh Mohammed, Yousef’s uncle, they find photographs of Zahid and KSM, who is also one of Yousef’s uncles, with close associates of Pakistani Prime Minister Nawaz Sharif. [Financial Times, 2/15/2003] According to another account, the pictures actually show Zahid with Sharif, and also with Muhammad Zia ul-Haq, president of Pakistan until his death in 1988. [Jacquard, 2002, pp. 66] Pictures of Osama bin Laden are also found. US agents are unable to catch Yousef because Pakistani agents tip him off prior to the US raids. Yousef is able to live a semi-public life (for instance, he attends weddings), despite worldwide publicity naming him as a major terrorist. The Financial Times will later note that Yousef, KSM, and their allies “must have felt confident that their ties to senior Pakistani Islamists, whose power had been cemented within the country’s intelligence service [the ISI], would prove invaluable.” [Financial Times, 2/15/2003] Several months later, Yousef and KSM unsuccessfully attempt to assassinate Benazir Bhutto, who is prime minister of Pakistan twice in the 1990s (see July 1993). She is an opponent of Sharif and the ISI. [Slate, 9/21/2001; Guardian, 3/3/2003] The Los Angeles Times will later report that KSM “spent most of the 1990s in Pakistan. Pakistani leadership through the 1990s sympathized with Osama bin Laden’s fundamentalist rhetoric. This sympathy allowed [him] to operate as he pleased in Pakistan.” [Los Angeles Times, 6/24/2002]
Spring 1993: World Trade Center Bombing Investigation Uncovers Links to Ali Mohamed
Not long after the World Trade Center bombing in February 1993 (see February 26, 1993), investigators discover a connection between some of the plotters, Ali Mohamed, and El-Sayyid Nosair (see November 5, 1990). The Wall Street Journal reports that investigators “went back to look at [Nosair’s] personal possessions. There, they finally saw the link to Mr. Mohamed.” Top secret US military documents obviously supplied by Mohamed are found among Nosair’s possessions. Still no action is taken against Mohamed. [Wall Street Journal, 11/26/2001; Posner, 2003, pp. 186-94]
Spring 1993: ’Blind Sheikh’ Plot to Crash Airplane into US Embassy in Egypt
In March 1995, Emad Salem, an FBI informant and an ex-Egyptian army officer, publicly testifies in a 1995 trial of the 1993 World Trade Center bombing plotters. He mentions a plot taking place at this time by Islamic radicals tied to the “Blind Sheikh,” Sheikh Omar Abdul-Rahman (see July 1990). A Sudanese Air Force pilot would hijack an airplane, attack Egyptian President Hosni Mubarak, then crash the plane into the US Embassy in Cairo, Egypt. Siddig Siddig Ali, who will be one of the defendants in the trial, asks Salem for help to find “gaps in the air defense in Egypt” so the pilot could “bomb the presidential house and then turn around, crash the plane into the American embassy after he ejects himself out of the plane.” Abdul-Rahman gives his approval to the plot, but apparently it never goes beyond the discussion stage. Although details of this plot are in public records of the World Trade Center bombing trial, both the 9/11 Congressional Inquiry and 9/11 Commission fail to mention it. [Lance, 2004, pp. 196; Intelwire, 4/8/2004] Abdul-Rahman is closely tied to bin Laden and in fact in 1998 there will be an al-Qaeda hijacking plot designed to free him from prison (see 1998). Individuals connected to Abdul-Rahman and al-Qaeda will also plot to crash an airplane into the White House in 1996 (see January 1996).
Spring 1993: Islamic Jihad Head Fundraises in US
Ali Mohamed helps Ayman al-Zawahiri enter the US for a fundraising tour and acts as his head of security during his stay. At the time, al-Zawahiri is known to have been the head of the militant group Islamic Jihad since the late 1980’s. He is also al-Qaeda’s de facto number two leader, though this is not widely known. This is apparently his second visit to the US; having previously paid a recruiting visit to the Al-Kifah Refugee Center in Brooklyn in 1989 (see 1986-1993). The exact timing of this second visit is disputed, but New Yorker magazine will report that “people at the FBI” assert “al-Zawahiri arrived in America shortly after the first bombing of the World Trade Center” in February 1993. Al-Zawahiri stays at Mohamed’s residence in Santa Clara, California, posing as a representative of a charity organization. It is said that not much money is raised. [New Yorker, 9/9/2002] Al-Zawahiri will make another apparently more successful fundraising trip to the US in either late 1994 or sometime in 1995 (see Late 1994 or 1995).
After February 26, 1993: CIA Obstructs FBI Investigation of ‘Blind Sheikh’ in 1993 WTC Bombing
After the 1993 WTC bombing (see February 26, 1993), New York District Attorney Robert Morgenthau’s investigators search El Sayyid Nosair’s belongings (see November 5, 1990 and After) and find a bomb formula which was quite similar to the bomb used to attack the WTC. This discovery would link Sheikh Omar Abdul-Rahman’s group to the bombing. The belongings also include a taped plea from Abdul-Rahman to destroy “the towers that constitute the pillars” of the civilization of “enemies of God.” Some suspect this is a reference to the WTC. But the FBI refuses to acknowledge and follow up on the bomb formula or other leads from Nosair. Morgenthau later concludes that the CIA may have pressured the FBI to back off from evidence which led to Abdul-Rahman, as well as blocking other investigative leads (see Late 1980s and After). [New York Times, 11/21/1994; New York Magazine, 3/17/1995]
