Anders Behring Breivik Sentenced: What You Need To Know About The Norway Massacre Case

08/24/2012 10:25 am ET

OSLO, Norway -- A chapter of a terror case that has haunted Norway for 13 months ended Friday as confessed mass killer Anders Behring Breivik was declared sane and sent to prison for bomb and gun attacks that killed 77 people and injured 200 others last year.

After deliberating for two months, a five-judge panel in Oslo's district court handed down a sentence of "preventive detention" of at least 10 years and a maximum of 21 years for the right-wing extremist. However, such sentences can be extended under Norwegian law as long as an inmate is considered dangerous.

Breivik, a 33-year-old Norwegian on a mission to expel Muslims from Europe, set off a car bomb that killed eight people outside government headquarters in Oslo and he then killed 69 others in a shooting rampage on Utoya island, where young members of the governing Labor Party had gathered for their annual summer camp. Breivik says he would appeal an insanity ruling but accept a prison term.
