Terrorist Anders Breivik's trial starts today

Anders Behring Breivik, who nine months ago carried the biggest terror shooting sprees at a summer camp on Utoya island, stands accused of killing 77 people by detonating a bomb in the centre of Oslo and opening fire on young people attending the camp.

The 33-year-old is charged with terrorism but he intends to plead not guilty. Breivik will argue that the attacks were a "political act" designed to prevents an "Islamic invasion of Norway".

Moreover, Breivik is expected to tell the court that he should be facing a military tribunal, and not a military court.

Breivik's lawyer intends to question a psychiatric report that deemed Breivik to be criminally insane.

If he is found to be insane, Breivik will be sent to a closed psychiatric ward; if found sane he faces just 21 years in prison for the killings. The sentence may be extended indefinitely if he is considered as a threat to society.
