This dramatic video shows the full destructive force of the car bomb set off by Anders Breivik that killed eight people last year in Oslo.
Two hours later Breivik, dressed as a policeman and heavily armed, massacred 69 people attending a Youth Labour Party Camp on the island of Utøya.
All but 10 were aged 21 or under.
Norway does not have life sentences but his term is likely to be lengthened every five years after the original term.
The footage below shows Breivik parking the van which contained the bomb. The CCTV operator, his suspicions clearly aroused, zooms in in an attempt to check out the vehicle.
