A week after the WTC bombing, an Iraqi-American is questioned by the FBI and then allowed to leave the country, despite evidence tying him to the bombing. Abdul Rahman Yasin is a US citizen but spent most of his life in Iraq until 1992, when he returned to the US. Two of the major WTC bomb plotters, Ramzi Yousef and Mohammed Salameh, lived in the apartment directly above Yasin’s. Several days after Salameh is arrested, the FBI searches Yasin’s apartment. They find traces of bomb explosives on a scale, a tool box, and a shirt. In the trash, they find jeans with an acid hole burned in them, and torn pieces of a map showing the route to Yousef’s other apartment. Yasin is taken to an FBI office and interrogated by Neil Herman, head of the FBI’s WTC bombing investigation, and others. Yasin gives information about Salameh, Yousef, and other participants in the bomb plot. Agents observe a chemical burn on his right thigh, making them suspect that he was involved in mixing the chemicals used in the bombing. The next day, he drives FBI agents to the apartment where the bomb was made. Yet Yasin will later be interviewed and claims that the FBI never asked him if he was involved in the bomb plot. Later that evening, he flies to Iraq. Herman will later say, “There was not enough information to hold him and detain him. And the decision was made, and he was allowed to leave.” [Los Angeles Times, 10/12/2001] In 2002, Iraqi Deputy Prime Minister Tariq Aziz will recall, “I have to tell you that we fear[ed] that sending Yasin back to Iraq… was a sting operation [for the US to] tell people later on, look, this man who participated in that event now is in Iraq, etc., and use it as they are doing now, using many false pretexts, you see, to hurt Iraq in their own way.” [60 Minutes, 6/2/2002] Yasin will be indicted in August 1993 for his role in the WTC bombing and the US later puts a $2 million bounty on his head. In October 2001, that will be increased to $25 million. In 2002, Yasin will be interviewed by CBS News in Iraq and will confess to involvement in the WTC bombing but says he was not an Iraqi government agent. Iraqi authorities will tell CBS that Yasin is still imprisoned without charge and has been in prison since 1994, but this has not been independently confirmed. Some continue to point to Yasin as evidence that Iraq was behind the WTC bombing. [Los Angeles Times, 10/12/2001; 60 Minutes, 6/2/2002]
April 2, 1993: WTC Bomber Yousef Placed on FBI’s ‘Ten Most Wanted’ List; Massive Manhunt Ensues
The FBI places Ramzi Yousef on its “Ten Most Wanted” list, after determining his prominent role in the 1993 World Trade Center bombing (see February 26, 1993). An international manhunt ensues. The FBI works with a State Department program that publicly offers generous rewards and a new identity for informants giving information about wanted terrorists. A $2 million reward is announced for information on Yousef and a large publicity campaign about the reward is launched, with a focus on Pakistan, India, Malaysia, and the Philippines. Huge numbers of matchboxes are distributed with Yousef’s photograph and reward information on them. In early 1995, one of Yousef’s associates will learn of the program and turn Yousef in for the reward money (see February 3-7, 1995). The matchbox program will be used for other wanted suspects, such as Abdul Rahman Yasin and Mir Kansi. However, Yousef’s uncle Khalid Shaikh Mohammed (KSM) will never be placed on the most wanted list before 9/11, and while there eventually will be a $2 million reward for him, no similar massive manhunt or large publicity campaign will take place for him, even after he is identified as a mastermind in the WTC bombing, Bojinka plot, African embassy bombings, and many other attacks.

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:
