Breivik called "Christian Norwegian Conservative." (See below: 'Christian may be incorrect'.)Closest main stream political party would be the 'Christian Unity Party' formed in 1998.  Jihad can be ruled out.

32 year-old Anders Behring Breivik
Shot kids for 90 minutes.
Seen at the Oslo bomb site.

   Update:  It gets much worse:  Police say at least 80 people have been killed at the camp.  Dressed as a policeman, he called the kids to gather around him.

Breivik, another photo.

Comment:  He reminds me of concerns expressed by the author of The Girl with the Dragon Tattoo series.  Stieg Larsson, a Swede, founded the Swedish Expo Foundation... to "counteract the growth of the extreme right and the white power-culture in schools and among young people." From Wikipedia

Added:  Death toll 84 at camp, 7 at bombing site.
He posted comments at Atlas Shrugs and posts with translations appear here. He's being identified as a "fundamentalist Christian"(Wrongly, see below). Bought 6 tons of fertilizer.
Added:  If gun laws didn't ban weapons, would this slaughter have gone so far? Power Line.
Added:  Grainy photo from chopper showing killer, bodies and a young man begging for his life.
Added: Fake facebook, Youtube material showing up.

Added:  1500 page English document, some of it cribbed from the Unabomber, some highly thought- out, some just retro crazy is described in some detail here. Original pdf here.   Norway has Europe's highest gun ownership, 1,400,000 guns in total or 31 weapons per 100 population.  Maximum penalty Breivik faces is 21 years under Norwegian law.

Added from World Net Daily:  "Terrorist proclaimed himself 'Darwinian,' not 'Christian'

Norwegian's manifesto shows Breivik not religious, having no personal faith".  People have taken time to read through the 1500 page manifesto.
