Oslo, Norway (CNN) — Anders Behring Breivik, the man who killed 77 people in a bomb attack and gun rampage just over a year ago, was judged to be sane by a Norwegian court Friday, as he was sentenced to 21 years in prison.
Breivik was charged with voluntary homicide and committing acts of terror in the attacks in Oslo and on Utoya Island on July 22, 2011.
He was sentenced to the maximum possible term of 21 years and was ordered to serve a minimum of 10 years in prison. The time he has already spent in prison counts toward the term.
The sentence could be extended, potentially indefinitely, in the future if he is considered still to pose a threat to society. Norway does not have the death penalty.
