With a personal fortune of around $250 million (estimates range from $50 to $800 million [Miami Herald, 9/24/2001] ), Osama bin Laden begins plotting attacks against the US from his new base in Sudan. The first attack kills two tourists in Yemen at the end of 1992. [New Yorker, 1/24/2000] The CIA learns of his involvement in that attack in 1993, and learns that same year that he is channeling money to Egyptian extremists. US intelligence also learns that by January 1994 he is financing at least three militant training camps in North Sudan. [New York Times, 8/14/1996; PBS Frontline, 2001; US Congress, 7/24/2003]
