A lawyer for the Norwegian who confessed to killing 77 people says the defense will call both a Muslim cleric and an anti-Islamic blogger to the stand to refute claims that his client is insane.
Geir Lippestad, who represents Anders Behring Breivik, wants their testimony to show there are others who share Breivik's world view.
Lippestad told public broadcaster NRK on Monday "we wish to call witnesses from both right-wing extremist and Islamist environments."
Lippestad said witnesses would include Mullah Krekar, a radical Iraqi cleric jailed in Norway for making death threats, and a prominent anti-Islamic blogger known as Fjordman.
Breivik denies criminal guilt for the July 22 attacks, saying they were part of an anti-Muslim revolution. His trial starts April 16.
