Norway's public broadcaster has shown for the first time video footage of right-wing extremist Anders Behring Breivik parking his van bomb that killed eight people in Oslo in July 2011.

Captured by video surveillance cameras, the images show Breivik parking his white van on July 22 at the very foot of a building tower that housed the prime minister's offices.

Breivik is seen getting out of the car in a security guard's uniform, and walking away briskly.
