Jordanian intelligence (the GID) makes a communications intercept deemed so important that King Abdullah’s men relay it to Washington, probably through the CIA station in Amman. To make doubly sure the message gets through it is passed through an Arab intermediary to a German intelligence agent. The message states that a major attack, code named “The Big Wedding,” is planned inside the US and that aircraft will be used. “When it became clear that the information was embarrassing to Bush administration officials and congressmen who at first denied that there had been any such warnings before September 11, senior Jordanian officials backed away from their earlier confirmations.” The Christian Science Monitor will call the story “confidently authenticated” even though Jordan has backed away from it. [International Herald Tribune, 5/21/2002; Christian Science Monitor, 5/23/2002] It has been reported elsewhere that in July 2001, Jordan warns the US that al-Qaeda is planning an attack inside the US, but it is unknown if this is referring to the same warning or a separate one (see July 2001).
In late July 2001, the king of Jordan will offer the US to send two battalions of Jordanian special forces to Afghanistan to eliminate al-Qaeda havens there (see July 24, 2001). Also in July 2001, Jordan briefly detains and interrogates Mohammed Haydar Zammar, who is a member of the Hamburg cell with three of the 9/11 hijackers (see July 2001). Zammar appears to have foreknowledge of the 9/11 plot around this time (see August 2001).
