The most important Egyptian in Bin Ladin's circle was a surgeon, Ayman al Zawahiri, who led a strong faction of the Egyptian Islamic Jihad. Many of his followers became important members in the new organization, and his own close ties with Bin Ladin led many to think of him as the deputy head of al Qaeda. He would in fact become Bin Ladin's deputy some years later, when they merged their organizations.²⁹

Bin Ladin Moves to Sudan
By the fall of 1989, Bin Ladin had sufficient stature among Islamic extremists that a Sudanese political leader, Hassan al Turabi, urged him to transplant his whole organization to Sudan. Turabi headed the National Islamic Front in a coalition that had recently seized power in Khartoum.³⁰ Bin Ladin agreed to help Turabi in an ongoing war against African Christian separatists in southern Sudan and also to do some road building. Turabi in return would let Bin Ladin use Sudan as a base for worldwide business operations and for preparations for jihad.³¹ While agents of Bin Ladin began to buy property in Sudan in 1990,³² Bin Ladin himself moved from Afghanistan back to Saudi Arabia.

In August 1990, Iraq invaded Kuwait. Bin Ladin, whose efforts in Afghanistan had earned him celebrity and respect, proposed to the Saudi monarchy that he summon mujahideen for a jihad to retake Kuwait. He was rebuffed, and the Saudis joined the U.S.-led coalition. After the Saudis agreed to allow U.S. armed forces to be based in the Kingdom, Bin Ladin and a number of Islamic clerics began to publicly denounce the arrangement. The Saudi government exiled the clerics and undertook to silence Bin Ladin by, among other things, taking away his passport. 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 1991.³³ By 1994, the Saudi government would freeze his financial assets and revoke his citizenship.³⁴ He no longer had a country he could call his own.

Bin Ladin moved to Sudan in 1991 and set up a large and complex set of intertwined business and terrorist enterprises. In time, the former would encompass numerous companies and a global network of bank accounts and nongovernmental institutions. Fulfilling his bargain with Turabi, Bin Ladin used his construction company to build a new highway from Khartoum to Port Sudan on the Red Sea coast. Meanwhile, al Qaeda finance officers and top operatives used their positions in Bin Ladin's businesses to acquire weapons, explosives, and technical equipment for terrorist purposes. One founding member, Abu Hajer al Iraqi, used his position as head of a Bin Ladin investment company to carry out procurement trips from western Europe to the Far East. Two others,Wadi al Hage and Mubarak Douri, who had become acquainted in Tucson, Arizona, in the late 1980s, went as far afield as China, Malaysia, the Philippines, and the former Soviet states of Ukraine and Belarus.³⁵
