April 23, 1993: FBI Discovers Follow-up Plot to WTC Bombing; Sudanese Diplomats Are Reportedly Involved

In the wake of the 1993 WTC bombing (see February 26, 1993), Emad Salem is rehired as an FBI informant. Because Salem has the confidence of the group around the “Blind Sheikh” Omar Abdul-Rahman connected to the bombing, the FBI is so desperate to hire him back that they pay him over $1 million to return. It takes time for Salem to fully regain confidences, but on April 23, 1993, Siddig Siddig Ali approaches Salem and asks him to participate in a series of bombings that he is planning. Siddig Ali explains that he wants to simultaneously bomb four landmarks in New York City: the Lincoln and Holland tunnel, the United Nations headquarters, and the New York FBI office. This will later be known as the “Landmarks” plot. Siddig Ali later tells Salem that he has friends in the Sudanese Embassy who had approved the plan and are willing to help with diplomatic license plates and credentials. Wearing a wire, over the next weeks Salem meets and records others participating in the plot. Many of them, including Siddig Ali, attended a training camp the FBI briefly monitored back in January 1993 (see January 16-17, 1993). [Miller, Stone, and Mitchell, 2002, pp. 113-114] The FBI will expand its surveillance of the plotters and roll up the plot a couple of months later (see June 24, 1993). The US will later eject two Sudanese diplomats, Siraj Yousif and Ahmed Yousif Mohamed, for suspicions of involvement in the plot. Both are said to be intelligence agents posing as diplomats. Later in 1993, the US also places Sudan on a list of terrorist countries. [New York Times, 8/18/1993; New York Times, 4/11/1996]
