A man who admits killing 77 people in a bomb and shooting attack in Norway has wept in court as one of his extremist videos was played as evidence - after showing no emotion while a list of his victims and how they died was read out.

Anders Breivik - who made a far-right salute as his trial began this morning before telling the court he doesn't recognise it's authority - has pleaded not guilty, claiming self-defence.

The 33 year old says he acknowledges his actions but won't apologise.
