Norway: Anders Behring Breivik insane, his lawyer says .. video inside ..
Lawyer Geir Lippestad: ''This whole case has indicated that he is insane''
The lawyer defending Anders Behring Breivik, who admitted carrying out Friday's mass killings in Norway, says his client is probably insane.
However he added it was too early to say Mr Breivik would plead insanity.
The bombing in Oslo and shooting spree on a nearby island killed 76 people. Mr Breivik is facing terrorism charges.
Police are considering also charging him with crimes against humanity, which carry a possible 30-year sentence, a prosecutor has said.
Mr Breivik's lawyer, Geir Lippestad, told reporters: "This whole case indicated that he is insane."
He said his client believed that he was in a war and that he would be vindicated in 60 years' time.
Mr Lippestad added that Mr Breivik had said he was part of an anti-Islam network that has two cells in Norway and several more abroad.
Norwegian police and researchers have cast doubt on such claims, but said they were investigating them.
Earlier on Tuesday, prosecutor Christian Hatlo told Aftenposten that a new charge of crimes against humanity, which could be brought under a 2008 law, was currently only "a possibility".
Police spokesman Sturla Henreiksboe told AFP news agency: "Police have so far cited... the law on terrorism but seeking other charges has not been excluded."
On Monday up to 250,000 people poured on to the streets of the capital, many of them raising up flowers in memory of the eight people killed in the Oslo blast and the 68 who died at a youth camp on Utoeya.
Later on Tuesday, police are due to formally release the names of the victims.
