Sudanese officials were hoping to expel Osama Bin Ladin to Saudi Arabia. “Saudi officials apparently wanted Bin Ladin expelled from Sudan. They had already revoked his citizenship, however, and would not tolerate his presence in their country. And Bin Ladin may have no longer felt safe in Sudan, where he had already escaped at least one assassination attempt that he believed to have been the work of the Egyptian or Saudi regimes, or both. In any case, on May 19, 1996, Bin Ladin left Sudan–significantly weakened, despite his ambitions and organizational skills. He returned to Afghanistan.”
