Anders Behring Breivik is probably insane, according to the lawyer defending him -- but it is still uncertain whether Breivik will plead insanity.
Breivik has admitted to carrying out the Utoya shootings and Oslo bomb attack, killing 76 people. Breivik is facing charges under Acts of Terrorism.
Geir Lippestad, Mr Breivik's lawyer, said: "This whole case indicated that he is insane."
According to Lippestad, Breivik believes that he is at war and that he will be vindicated in 60 years.
One prosecutor has indicated that Breivik may also be charged with crimes against humanity, which carry a potential 30 year sentence.
Sturla Henreiksboe, a spokesperson for the police, told AFP news agency: "Police have so far cited... the law on terrorism but seeking other charges has not been excluded."
Breivik has claimed that he is part of an anti-Islam network that has two cells in Norway and many more abroad but police and researchers have cast doubt on these claims, adding that they will continue to investigate them.
Lippestad confirmed that he himself had not received any threats as a result of his position as the defendant's lawyer and he added that the legal system is part of the democratic system of Norway and that he is "proud" to be a part of it.
