When al-Qaeda operative Ramzi bin al-Shbih is captured in Karachi, Pakistan, in September 2002 (see September 11, 2002), a sign-in book is found with names and passport numbers. US investigators discover that one of Osama bin Laden’s wives and two of his sons had signed in, and their passports had been issued in their real bin Laden names by Sudan in early 2002, through the Sudanese Embassy in Islamabad, Pakistan. President Bush is briefed on this, and US intelligence figures suspect that high-ranking Sudanese leaders must have approved the passports and are playing a double game of supporting bin Laden and the US at the same time. The Sudanese government suggests that the officials involved may have been paid off. In a show of good faith, they provide vigorous assistance on several other CIA initiatives.
