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]
