Norwegians are today paying tribute to 77 people killed in last month's bombing and shooting massacre by a right-wing extremist.

Survivors of a massacre which claimed the lives of 69 people in Norway last month carried flowers to the site of the killings today, laughter blending with tears as they remembered the joys of an island youth camp that turned into a scene of horror.

A judge denied Anders Behring Breivik the public stage he wanted to air today, ruling that the first hearing for the man who has confessed to Norway's twin terror attacks be held behind closed doors.

More than 25 people were feared dead tonight after a bomb ripped open buildings in the heart of Norway's government and a man dressed as a police officer opened fire at an island youth camp connected to the ruling party.
