Hassan al-Turabi comes to power in Sudan in 1989, and his beliefs are ideologically compatible with bin Laden’s. With the Afghan war ending and the Afghans beginning to fight amongst themselves, al-Turabi sends a delegation and a letter to bin Laden, inviting him to collaborate and move to Sudan. Bin Laden agrees to the offer, but moves slowly. He sends advance teams to buy businesses and houses. He also visits Sudan himself to establish a relationship with al-Turabi. Gradually, about 1,000 bin Laden supporters move to Sudan. But bin Laden also keeps offices and guest houses in Pakistan, as well as training camps in Afghanistan, including the Darunta, Jihad Wal, Khaldan, Sadeek, Al Farooq, and Khalid ibn Walid camps. US-al-Qaeda double agent Ali Mohamed plays an important role in the move (see Summer 1991). [Gunaratna, 2003, pp. 39-41]
