The Norwegian anti-Islam militant Anders Behring Breivik who massacred 77 people in July arrived under heavy armed guard at an Oslo courthouse on Monday, lifting his arm in what he has called a rightist salute as his trial began.

I do not recognise the Norwegian courts. You have received your mandate from political parties which support multiculturalism, Breivik told the court. I do not acknowledge the authority of the court.

Breivik, 33, has admitted setting off a car bomb that killed eight people at government headquarters in Oslo, then massacring 69 in a shooting spree at an island summer camp for Labour Party youths.
