Early 1990s: US Intelligence Monitoring Bin Laden in Sudan

It has not been revealed when US intelligence begins monitoring bin Laden exactly, though the CIA was tailing him in Sudan by the end of 1991 (see February 1991- July 1992). But in late 1995 the FBI is given forty thick files on bin Laden from the CIA and NSA, mostly communications intercepts (see October 1995). The sheer amount of material suggests the surveillance had been going on for several years. Dan Coleman, an FBI agent working with the CIA’s bin Laden unit, will begin examining these files and finds that many of them are transcripts from wiretapped phones tied to bin Laden’s businesses in Khartoum, Sudan, where bin Laden lives from 1991 to 1996. [Miller, Stone, and Mitchell, 2002, pp. 148-149; Wright, 2006, pp. 242-244] CIA Director George Tenet will later comment, “The then-obscure name ‘Osama bin Laden’ kept cropping up in the intelligence traffic.… [The CIA] spotted bin Laden’s tracts in the early 1990s in connection with funding other terrorist movements. They didn’t know exactly what this Saudi exile living in Sudan was up to, but they knew it was not good.” [Tenet, 2007, pp. 100] The London Times will later report that in Sudan, “bin Laden used an $80,000 satellite phone and al-Qaeda members used radios to avoid being bugged…” [London Times, 10/7/2001] Bin Laden is mistaken in his belief that satellite phones cannot be monitored; a satellite phone he buys in 1996 will be monitored as well (see November 1996-Late August 1998).
