Memorial services are taking place across Norway to commemorate one year since 77 people were killed and 242 other injured in two attacks carried out in Oslo and on the island of Utoeya.
Anders Brevik coordinated and carried out a car-bomb attack that killed nine people, while he shot 69 people dead at a youth camp.
The Norwegian Royal family and the country’s Prime Minister paid their respects with the relatives of victims.
The attacks were considered the worst act of violence in Norway since the Second World War and sparked a national debate about the nature of tolerance in the country.
Breivik who admitted to both crimes still remains on trial, his verdict is expected to be announced next month.
