Norwegian mass murderer Anders Behring Breivik, who is serving a 21-year sentence for killing 77 people in a bomb and gun rampage last year, has complained that he is being held in inhumane conditions and is being denied freedom of expression.

A chapter of a terror case that has haunted Norway for 13 months has closed with confessed mass killer Anders Behring Breivik being declared sane and sent to prison for bomb and gun attacks that killed 77 people and injured 200 others last year.

Those expecting Anders Behring Breivik to spend the rest of his days alone in a cramped cell will be disappointed when the far-right fanatic is sentenced on Friday for killing 77 people in a bomb and gun rampage last year.
