Oslo:
A court on Friday extended the isolation detention of the man who confessed to the killings of 77 people in Norway by four more weeks.
The Oslo District Court said Anders Behring Breivik must be kept in complete isolation by police partly for fear he would tamper with evidence and contact possible accomplices.
Judge Hugo Abelseth acknowledged that Breivik had described his isolation as "boring and monotonous, and as a sadistic torture method," but said he must nonetheless spend at least four more weeks there. He said his next hearing would be September 19.
Breivik had appeared at a closed hearing under heavy police protection. His earlier request to wear a long black tuxedo to the session had been rejected by the Oslo District Court, which described it as "unnecessarily disturbing and provocative."
The 32-year-old right-wing extremist has admitted to killing eight people when he exploded a truck bomb outside government offices in Oslo, then fatally shooting 69 people at a youth camp on Utoya island nearby.
Breivik denies criminal guilt because he believes the massacre was necessary to save Norway and Europe. He said the attacks were an attempt at cultural revolution, aimed at purging Europe of Muslims and punishing politicians that have embraced multiculturalism.
The hearing came as survivors, relatives and close friends of the victims were visiting Utoya on Friday and Saturday to grieve at the island massacre site. Some 1,500 people were expected on the island.
Breivik arrived at the hearing - his second court appearance since the July 22 attacks - in a black car under heavy escort. His lawyer Geir Lippestad said he was dressed in a dark suit and appeared calm, but showed no remorse.
"In his explanations he says these acts were gruesome, but necessary, and he hasn't changed his view on that," Lippestad said after the 30-minute hearing.
"He said it was tough to be in isolation. He didn't say that much more," Lippestad said. "It's natural to feel that it's tough to sit isolated in a small room."
Survivors were not allowed access to the court, but were represented by lawyers.
"It would have been good for my clients to see him in handcuffs and chains around his feet under police escort," said Brynjar Meling, a lawyer for one of the survivors.
Another lawyer representing the victims, Sigurd Klomsaet, said Breivik appeared to lack any humility.
"His comprehension for the pain and the hurt he has caused others is completely absent. Instead, he is fully occupied with his own situation," Klomsaet said.
If found guilty on terrorism charges, Breivik could be sentenced to 21 years in prison. An alternative custody arrangement - if he is still considered a danger to the public - could keep him behind bars indefinitely.
Norway's General Director of Health Bjoern Inge Larsen told reporters he hoped that the visit to Utoya would help families come to grips with the deaths.
"The police officer taking care of each family will take that family to the place where we found each of the killed young grown-up people," Larsen said before the visit. "Of course, that will be a very difficult day for the people coping out there, but in the long run we know that seeing the scene of where these murders were taking place is actually helpful."
On Sunday, a national memorial service was to be held at Oslo Spektrum arena, marking the end of a month of mourning in the Scandinavian country.
In the first court hearing on July 25, officials decided Breivik could be detained for eight weeks, including four weeks in isolation, meaning he has not been given access to television, newspapers and the Internet.
At Friday's hearing the court met to decide on a police request to extend the isolation period for another four weeks.
