The 32-year-old Norwegian suspected of killing as many as 93 people in a bombing and shooting rampage arrived on Monday in a closed Oslo courtroom for his first remand hearing, state media reported.

News agency NTB said Anders Behring Breivik was to face arraignment, with judge Kim Heger to decide on the prosecutor's call for him to be placed in detention for eight weeks as the investigation proceeds.

That is double the normal, renewable period.

NTB said the vehicle bringing Behring Breivik into the courthouse arrived through a back entrance, leading to the basement of the building.

People waiting to catch a glimpse of him cried 'traitor' and 'bloody killer', the agency said.

Behring Breivik's lawyer, Geir Lippestad, came in through the main entrance, having to force a passage through hundreds of journalists waiting since early morning.

Police have said a trial could be a year away. The maximum jail term in Norway is 21 years, although that can be extended if there is a risk of repeat offences.

"In theory he can be in jail for the rest of his life," said Staale Eskeland, professor of criminal law at the University of Oslo.

Craving for publicity

Breivik, a self-confessed mass killer, has said through his lawyer that he wants to explain his motives at the hearing.

The 32-year-old, who portrays himself as crusader against a tide of Islam in a rambling 1,500-page online manifesto, says he wants to explain acts he deemed 'atrocious' but 'necessary'.

The hearing, expected to start after 1 p.m. (1100 GMT), has opened a debate about freedom of expression, with many people opposed to allowing Breivik to expound his radical views.

A judge has also ruled that the trial will be closed for the Norwegian public.

More than 60,000 had signed up to a Facebook page called 'Shut the doors on Monday', calling on the court to deny Breivik the publicity he craves.

Another Facebook group called 'Boycott Anders Behring Breivik' carried the message: "He has planned this stage, to get propaganda. Do NOT let him get that freedom...Boycott all media describing the Norwegian terrorist and his beliefs."

Breivik has asked to wear a uniform in court, but his lawyer, Geir Lippestad, said he did not know what type. The killer was dressed as a policeman during his shooting spree.

Breivik has not served in the armed forces but in some of the pictures he posted on the Internet before his killing spree he was dressed in a military-style outfit.

A small group of people gathered outside the Oslo Court House, although they were outnumbered by journalists.

Lippestad said his client had admitted to the shootings at a Labour youth camp and a bombing that killed seven people in Oslo's government district, but that he denies criminal guilt.

"He has been politically active and found out himself that he did not succeed with usual political tools and so resorted to violence," Lippestad told TV2 news.

"I await a medical assessment of him," he said.

Saving Europe

The worst peacetime massacre in Norway's modern history was driven by Breivik's self-imposed mission to save Europe from perceived threats of Islam, immigration and multi-culturalism.

That he surrendered to police when finally confronted on the tiny island of Utoeya after shooting dead 86 youngsters underlines his desire to secure a public platform.

Breivik wrote in his manifesto, posted hours before his attacks, that if he survived his assault and was arrested, this would 'mark the initiation of the propaganda phase'.

Norwegian newspapers focused on the victims as shock turned to mourning, giving chilling new accounts of the island massacre and focusing on acts of bravery which saved lives.

The main broadsheet Aftenposten led with 'Sorrow unites Norway' and printed a picture of a central Oslo square filled with flowers and lit candles in remembrance of the dead.

Daily Dagsavisen asked 'Why didn't you come earlier?' citing screams by youth as police arrived on Utoeya island on Friday - an hour after they were notified of the shooting.

Police believe Breivik acted alone after losing faith in mainstream parties, even those that have gained popularity and parliamentary seats on anti-immigration policies in otherwise liberal, tolerant European nations, including affluent Norway.

The attack was likely to tone down the immigration debate ahead of September local elections, analysts said, as parties try to distance themselves from Breivik's beliefs and reinforce Norwegians' self-image as an open, peaceful people.

Norway's immigrant numbers nearly tripled between 1995 and 2010 to almost half a million. The sense that many were drawn by Norway's generous welfare handouts helped spur the growth of the Progress Party which became Norway's second biggest in parliament after the 2009 election on a largely anti-immigration platform.

'Scheming to resist'

Breivik was once a member of the party, but left complaining it was too politically correct. It was then he began scheming to 'resist', burying ammunition more than a year ago, weight-lifting, storing up credit cards and researching bomb-making while playing online war games.

After three months of laboriously pounding and mixing fertiliser, aspirin and other chemicals on a remote farm, Breivik drove a hire car packed with the results to the centre of Oslo on Friday, triggering the device outside government offices, killing seven and shattering thousands of windows.

He then drove to the small island of Utoeya, 45 km (28 miles) away. Dressed as a policeman, he calmly shot down youngsters at a youth summer camp of the ruling Labour Party. His terrified victims tried to hide under beds or in the woods. Some leapt into the lake and tried to swim to the mainland.

"This is going to be an all-or-nothing scenario," Breivik wrote in his English-language online journal on the morning of the attack.

"First coming costume party this autumn, dress up as a police officer. Arrive with insignias:-) Will be awesome as people will be very astonished:-)."

A surgeon at a hospital that treated 35 of the wounded said Breivik may have used 'dum-dum' bullets for maximum damage.

"These bullets don't explode inside the body but fragment into pieces more quickly than other bullets," Colin Poole, chief surgeon of the Ringerike district hospital, said.

While Breivik was stalking his prey on Utoeya, it took police a full hour to get a team of elite forces to the island after one boat, overloaded with officers and equipment, was forced to stop when it began to take on water.

Norwegian television managed to charter a helicopter and filmed the killer before the police showed up. When the armed team did arrive, Breivik gave himself up without a fight.
