Hassan al-Turabi
Bin Laden's increasingly strident criticisms of the Saudi monarchy led the government to attempt to silence him. According to the 9/11 Commission Report, "with help from a dissident member of the royal family, he managed to get out of the country under the pretext of attending an Islamic gathering in Pakistan in April 1991." Another report has bin Laden retrieving his passport from the Saudi government to go to Peshawar in March 1992 to mediate the Afghan Civil War. In any case Hassan al-Turabi, leader of the National Islamic Front, had invited bin Laden to "transplant his whole organization to Sudan" in 1989. Bin Laden's agents had begun purchasing property in Sudan in 1990. Bin Laden moved to Sudan in 1992.
