A video on the YouTube website promoting a fight against Islam apparently shows pictures of the man suspected of a gun and bomb attack in Norway, wearing a wetsuit and pointing an automatic weapon.
The pictures appear at the end of an approximately 12-minute video called Knights Templar 2083. The video was posted at http://www.youtube.com/watch?v=vQOfH8Dj1mw.
The pictures in the video also appeared on the now closed Facebook page of Anders Behring Breivik, detained after 85 people were gunned down at a youth camp and another 7 killed in a bomb attack on Friday.
A Norwegian discussion website, http://www.freak.no, also had a link to a 1,500-page book called 2083 - A European Declaration of Independence.
It was not possible to verify who uploaded the video, which was posted on July 22 by an Andrew Berwick.
The 2083 book is also signed by an Andrew Berwick. The author says within the document that Andrew Berwick is an Anglicized version of Anders Breivik.
