Anders Breivik, the man accused of massacring 93 people in dual attacks in Norway, has made his first appearance in court - and refused to plead guilty.

In a statement read by the judge he said that the deaths were necessary to save Europe from Marxism and the colonisation of Norway by Muslims.

The judge then ordered Breivik to spend a month in isolation after he claimed that there are two other cells in his far-right organisation.
