On August 4, 2006, the Al-Hesbah website published instructions on "How to Kill a Crusader in the Arabian Peninsula." The document was signed by Amer Al-Najdi, and dated June 15, 2006.
Al-Najdi instructs his readers in some possible ways to kill a Westerner, from choosing the victim through following him through the stage of the actual killing.
