Al Jazeera's Jonah Hull reports on developments from Norway:
Amid much speculation as to the motive behind these attacks, speculation that has centred on the possible involvement of international militant groups, perhaps al-Qaeda linked groups, the police are now saying that they believe there is no link to international militant groups.
They believe that this man may well have been acting alone. They have drawn a comparison between these attacks and the Oaklahoma bombings in the United States saying they resemble far more that attack than the 9/11 attacks, suggesting that this was some sort of a self-motivated attack perhaps by this man acting entirely alone without links to any wider groups or causes.
TV2 Norway has just been on air suggesting this man has links to right-wing extremism. So that's where the investigation appears now to be heading, looking rather at a self-motivated attack possibly by a Norwegian man acting alone without necessarily any links to international militant groups or al-Qaeda.
