The trial of confessed Norwegian mass murderer Anders Behring Breivik has been set to begin April 16 of next year.

Breivik has confessed to killing 77 people in a pair of deadly attacks in Norway last July. His trial date, announced at a hearing in Oslo Monday, is dependent on a psychiatric evaluation finding Breivik fit to be held criminally responsible for his actions.

It was Breivik's fourth pre-trial hearing, but the first that was open to the public. Dozens of people, some of them survivors of Breivik's attack, crowded the courtroom for the proceedings, hoping to find closure.

The 32-year-old Breivik blew up a fertilizer bomb outside Norway's government headquarters on July 22, killing eight people. He then moved on to a Labor Party youth camp where he shot to death 69 more people, most in their teens and early 20's, before surrendering to police. He said the attack was part of his campaign to stop Muslims from taking over Europe.

The court on Monday extended Breivik's custody for another 12 weeks — until February 6. Toward the end of the proceedings, Breivik asked to address the survivors of his massacre, but the judge did not allow him to do so.
