The man who massacred 77 people in gun and bomb attacks in Norway last year has told a court he carried out the attacks, but he has pleaded not guilty to the crimes and claimed he acted in self-defence.
Anders Breivik sat and listened without emotion as prosecutors described how he shot and killed young people at a summer camp on the island of Utoeya after detonating a car bomb close to government offices in Oslo.
He only lost his composure, shedding tears when the court played his own propaganda film, as Professor Jo Stigen from the University of Oslo explains.
