Norway PM: Extreme views 'must be tolerated'

Norwegian PM Jens Stoltenberg has said that extreme views must be tolerated in an open, democratic society, but can never be used to justify violence.

His comments came at a media conference following last Friday's attacks in Oslo and on the island of Utoeya.

Anders Behring Breivik, a far-right extremist, has admitted the bomb and gun attacks that killed at least 76 people.
