Anders Behring Breivik wants to tell Norway and the world why he killed at least 93 people in a bomb attack and shooting rampage, but prosecutors have asked for Monday's custody hearing to be closed to the public.

The Oslo district court judge decided Monday to hold the arraignment behind closed doors for Anders Behring Breivik, the man who has confessed to the twin attacks on Friday that killed 93 people in Norway, depriving him of the platform he's looking for to air his belief that Europe must be saved from Muslim colonization.

A judge ordered eight weeks detention on Monday for Breivik who has admitted a bombing and shooting massacre that killed about 90 people and who claimed in court to have two more groups of collaborators. Custody, in line with prosecutors' request, will allow them to investigate the case against Breivik, 32, an anti-Islamic zealot who has previously claimed sole responsibility for Friday's attacks. The custody can be extended.
