Flowere lay outside the courthouse where Breivik's trial is set to last 10 weeks
Roses are left on a fence outside the Oslo district courtroom where Anders Behring Breivik, who killed 77 people in twin attacks in Norway last year, is on trial. Thousands of Norwegians are to gather in Oslo to protest against Breivik by singing a folk song he hates and which he considers a Marxist indoctrination method.
