Norway mulls new massacre charge

The names of the dead were revealed as an estimated 150,000 people gathered to mourn them and the eight others who died in the Oslo bombing.

It is hoped that identification of all the 76 victims will be completed by Thursday.

One of the first Utoya victims to be named was 51-year-old Trond Berntsen, the stepbrother of Crown Princess Mette-Marit.

He was an off-duty police officer and reports suggest he saved his 10-year-old son before approaching gunman Anders Breivik, but became one of his first victims.

While the youngest victim is believed to be 14-year-old Johannes Buo, an AUP activist from southern Norway who has not been seen since the shooting.

Details of others, including Gunnar Linaker, 23, who was described by his family as a "big bear" and young politician Tore Eikeland, 21, have now been reported.

Linaker's father was talking to his son on the phone when the gunman launched his attack and said: "The last thing I heard was: 'Dad, dad there is a shooting, I have to go."

While Eikeland was the leader of the Labour youth movement in the county of Hordaland in western Norway.

The mayor of his home town described him as "very talented and one of the most solid youths I have ever met.

Judge Kim Heger ruled that the hearing should be held behind closed doors on the grounds Mr Breivik might have used it to send signals to accomplices.

Mr Hatlo said Mr Breivik claimed he had worked in a cell, or group, and that there were two other cells working with him.

Although police sources say other groups are unlikely, Mr Hatlo said he "cannot completely, and I stress completely, rule out that others were involved in what happened".

Mr Breivik was remanded in custody for eight weeks, the first four in full isolation.

He said his operation had not been aimed at killing as many people as possible but that he wanted to create the greatest loss possible to Norway's governing Labour Party, which he accused of failing the country on immigration.

The bomb in Oslo targeted buildings connected to the Labour Party government, and the youth camp on Utoeya island was also run by the party.

In addition to those killed, at least 96 people were injured in the attacks.
