Anders Breivik has said he will not appeal against his prison sentence for the massacre of 77 people in bomb and gun attacks in Norway last year.

Prosecutors today asked a court to send confessed mass killer Anders Breivik to a mental institution instead of prison for his massacre of 77 people in a gun and shooting rampage.

Anders Breivik tried to defend his massacre of 77 people today, insisting he would do it again and calling his rampage the most “spectacular” attack by a nationalist militant since the Second World War.

The Norwegian far-right gunman who massacred 77 people last summer gave a clenched-fist salute, smirked at the court, and pleaded not guilty on the first day of a trial that threatens to turn into a “circus” showcasing his anti-Islamic views.
