From Osama bin Laden’s February 22, 1998, statement of jihad against Jews and Crusaders: ” ‘…in compliance with Allah’s order, we issue the following fatwa to all Muslims: The ruling to kill the Americans and their allies–civilians and military–is an individual duty for every Muslim who can do it in any country in which it is possible to do it, in order to liberate the al-Aqsa mosque [in Jerusalem] and the holy mosque [Mecca] from their grip.’ ”
