Anders Behring Breivik pleads not guilty to murder
The man who carried out bomb and gun attacks in Norway last year which left 77 people dead has pleaded not guilty at the start of his trial in Oslo.
Anders Behring Breivik attacked a youth camp organised by the governing Labour party on the island of Utoeya, after setting off a car bomb in the capital.
He told the court he "acknowledged" the acts committed, but said he did not accept criminal responsibility.
If the court decides he is criminally insane, he will be committed to psychiatric care; if he is judged to be mentally stable, he will be jailed.
