At a Norway police press conference on July 23 national police chief Sveinung Sponheim said that Breivik has made Internet postings which "suggest that he has some political traits directed toward the right, and anti-Muslim views, but if that was a motivation for the actual act remains to be seen". During the conference the term "Christian fundamentalist" was used.
If the Oslo blast was caused by a vehicle bomb, it could not have been assembled in a private apartment, but must have been prepared elsewhere, either in the city or outside it. Vehicle bombs are widely used for terrorism not only in Pakistan, Afghanistan and the Middle East but also in the North Caucasus, which leads one to speculate that as there are several thousand Chechen and Ingush radicals living in Norway, there can be no shortage of experts in the field, and the individuals or group who organized the July 22 bombing must have got their expertise from somewhere. However, such speculation is probably misguided, at least at this stage.
Document.no has posted a list of all the comments Breivik has left on its site. There is a Google-ish English translation here.
A second shooter may still be at large.
The death toll continues to mount.
Berlingske reports that Breivik gave himself up voluntarily to Norwegian police.
