Anders Breivik declared sane and jailed for 21 years

The mass murderer Anders Behring Breivik has been sentenced to 21 years in prison after a court in Norway found him to be sane.

The right-wing extremist admits killing 77 people last year, in a bomb attack outside government offices in Oslo and a shooting spree at a political youth camp.

Breivik faces the possibility of indefinite extensions to his sentence.
