Gutbi al-Mahdi, head of Sudan’s intelligence agency, sends a letter to David Williams, an FBI station chief. It reads, “I would like to express my sincere desire to start contacts and cooperation between our service and the FBI. I would like to take this opportunity with pleasure to invite you to visit our country. Otherwise, we could meet somewhere else.” Apparently the FBI is very eager to accept the offer and gain access to Sudan’s files on bin Laden and his associates. The US had been offered the files before (see March 8, 1996-April 1996; April 5, 1997), but the US position was that Sudan’s offers were not serious since Sudanese leader Hassan al-Turabi was ideologically close to bin Laden. But al-Turabi has lost power to moderates by this time, and in fact he is placed under arrest in 1998. There is a political battle between US agencies over the Sudanese offer, and in the end the State Department forbids any contact with al-Mahdi. On June 24, 1998, Williams is obliged to reply, “I am not currently in a position to accept your kind invitation.” Al-Madhi later will complain, “If they had taken up my offer in February 1998, they could have prevented the [US embassy] bombings.” Tim Carney, US ambassador to Sudan until 1997, will say, “The US failed to reciprocate Sudan’s willingness to engage us on serious questions of terrorism. We can speculate that this failure had serious implications – at the least for what happened at the US Embassies in 1998. In any case, the US lost access to a mine of material on bin Laden and his organization.” One of the plotters in the bombings is Fazul Abdullah Mohammed (a.k.a. Haroun Fazul), who is living in Sudan but making trips to Kenya to participate in the bombing preparations. Sudan has files on him and continues to monitor him. Sudan also has files on Saif al-Adel, another embassy bomber who has yet to be captured. Sudan also has files on Wadih El-Hage and Mamdouh Mahmoud Salim, both of whom have contact with members of the Hamburg al-Qaeda cell (see September 16, 1998; Late 1998; 1993). Salim even attends the same small Hamburg mosque as 9/11 hijackers Mohamed Atta and Marwan Alshehhi. Vanity Fair magazine will suggest that if al-Madhi’s offer had been properly followed up, both the embassy bombings and the 9/11 attacks could have been foiled. [Vanity Fair, 1/2002] It is later revealed that the US was wiretapping bin Laden in Sudan on their own (see Early 1990s).
