Clearly, there is a pattern: eleven hijackers appear likely to have fought in Chechnya, and two others are known to have gone missing. It is possible that others have similar histories, but this is hard to confirm because “almost nothing [is] known about some.” [New York Times, 9/21/2001] Indeed, a colleague later claims that hijackers Mohamed Atta, Marwan Alshehhi, Ziad Jarrah, and would-be hijacker Ramzi Bin al-Shibh wanted to fight in Chechnya but were told in early 2000 that they were needed elsewhere. [Washington Post, 10/23/2002; Reuters, 10/29/2002] Reuters later reports, “Western diplomats play down any Chechen involvement by al-Qaeda.” [Reuters, 10/24/2002]
