Confessed mass killer Anders Behring Breivik was ordered to remain in pre-trial detention for eight weeks Monday during a closed court hearing in which he was cut off from making statements irrelevant to the case, a judge said.

The 32-year-old right-wing extremist has confessed to setting off a bomb in downtown Oslo and massacring dozens at an island youth camp outside the city, killing 77 people on July 22.

The Oslo District Court approved a police request to keep Breivik in custody on terror charges for another eight weeks — four of them in solitary confinement — as they prepare a formal indictment.

Judge Anne Margrethe Lund said she stopped Breivik "on a few occasions" when he tried to make statements during the court hearing, his third since being arrested following the carnage on Utoya island.

"He wanted to communicate something to the court. It wasn't relevant for the decision that was to be made today and therefore he wasn't allowed to say anything further," Lund told reporters after the hearing.

Breivik's defense lawyer Geir Lippestad also told reporters that his client tried to address the court but declined to give details, citing a gag order.

The ruling means police can continue to hold Breivik in custody until Nov. 14 when a new detention hearing will be held. But they can only hold him in isolation until Oct. 17 because decisions on solitary confinement must be reviewed every four weeks.

Prosecutors began wrapping up the International Criminal Court's landmark first trial on Thursday by urging judges to convict a Congolese warlord of recruiting hundreds of child soldiers and sending them to fight and kill in his country's brutal conflict.

Deputy Prosecutor Fatou Bensouda told judges that evidence in the trial that began in January 2009 gave voice to children that militia leader Thomas Lubanga had "transformed into killers; those girls that Mr. Lubanga offered to his commanders as sexual slaves."

Bensouda said the armed wing of Lubanga's Union of Congolese Patriots political party trained hundreds of children in 20 camps scattered across the Ituri region of eastern Congo in 2002-2003.

"They were used to fight in conflicts. They were used to kill, rape and pillage," she added.

Actress Angelina Jolie, who is a goodwill ambassador for the U.N. High Commissioner for Refugees, was among dozens of people who watched proceedings from the court's public gallery. She made no comment to reporters.

The confessed killer in Norway's twin terror attacks that claimed 77 lives has presented a long list of "unrealistic" demands, including the resignation of the government and that his mental condition be investigated by Japanese specialists, his defense lawyer said Tuesday.

Geir Lippestad told the Associated Press his client has two lists of demands. One consists of requests common among inmates such as for cigarettes and civilian clothing. The other is "unrealistic, far, far from the real world and shows he doesn't know how society works," Lippestad said by telephone.

Lippestad said 32-year-old Anders Behring Breivik links this second list to his willingness to share information about two other alleged terrorist cells that Breivik has mentioned during questioning.

"They are completely impossible to fulfill," Lippestad said, adding that although Breivik has agreed to be examined by local psychiatrists, he also wants to be investigated by Japanese specialists.

"He claims the Japanese understand the idea and values of honor and that a Japanese (specialist) would understand him a lot better than any European would."
