Breivik's sentence, the maximum allowed in Norway, can be reviewed and extended indefinitely if the far-right extremist responsible for Europe's deadliest peacetime gun rampage is deemed a continued threat to society.
Knut Storberget, who was Norway's justice minister at the time of the attacks, hailed the sentence, telling television channel TV2: "It's a good basis for him to stay in prison for the rest of his life."
"It's the heaviest sentence he could get."
Norway's penal code does not have the death penalty or life in prison, and the maximum prison term for Breivik's charges is 21 years. However, inmates who after that are still considered a threat to society can be held indefinitely.
