Anders Behring Breivik, the man responsible for the Norway attack on Friday, plead not guilty to "committing acts of terrorism."

At a closed hearing in Oslo on Monday, Breivik said that he was trying to "save Europe," not trying to kill as many as possible.

Norwegian courts acted quickly after police apprehended Breivik Friday evening. The hearing, which a judge ultimately decided would not be open to the public, occurred just three days after Breivik orchestrated two devastating attacks that killed at least 94 people in Oslo.

Judge Kim Heer closed the hearings, fearing that Breivik would use a public event as a platform to aggrandize his radical beliefs. Breivik, who calls himself a "Justiciar Knight," has admitted to the attacks, but has not claimed any criminal responsibility.

"It is clear that there is concrete information that a public hearing with the suspect present could quickly lead to an extraordinary and very difficult situation in terms of the investigation and security," Heer said in a statement.

Breivik will be jailed for at least eight weeks before the trial, half of which will be in complete isolation. During the first four weeks in detainment, the right-wing extremist will not be allowed to write letters or see visitors.

Believing in a severe anti-Muslim agenda, Breivik committed the attacks as a political statement against Norway's immigration policy and Europe's wider acceptance of Muslims. Before the events on Friday, Breivik sent out a 1,500 page manifesto titled "2083," in which he outlined his beliefs.

"If you are concerned about the future of Western Europe you will definitely find the information both interesting and highly relevant," Breivik addressed his readers.

He said he believed that there is an Islamic colonization of Western Europe underway, one which is aided by the rise of "cultural Marxism." Breivik claims he was recruited by a militant right-wing group in Britain, and the police are currently investigating Breivik's ties to extremism. In his book, Breivik calls his fight the "Western European Resistance."

On July 22, Breivik detonated a car bomb outside of government headquarters in Oslo, killing seven people and injuring dozens more. Shortly after the bombing, while police were evacuating the city center, Breivik opened fire on an island summer camp outside the city. He was wearing a police uniform when he attacked teenagers at a government-sponsored diplomatic retreat.

He was apprehended by counter-terrorism police on Utoeya Island, but not before he shot and killed at least 94 people.

The attack was the deadliest in Europe since the 2004 school shooting in Beslan, Russia, during which 350 people died.
