The Norwegian man who has admitted to last week's deadly bombing and shooting campaign has told an Oslo courtroom he had two more groups of collaborators working with him. Judge Kim Heger said after the closed-door hearing that the suspect, 32-year-old Anders Behring Breivik, admitted the facts of the case, but did not plead guilty.Mr Heger told a news conference that the accused made statements today that require further investigation, including that there are two more cells in their organisation. Breivik told the court that he acted to save Europe from Islam. He had previously said he had acted alone. The judge remanded him in custody for eight weeks, but there was no guilty plea entered. Breivik will be held in solitary confinement for the first four weeks, with a ban on all communication with the outside world in a bid to aid a police investigation into his acts. The custody can be extended.A trial could be a year away. Breivik faces terrorism charges for allegedly bombing the prime minister's office building in Oslo, then shooting participants at a youth camp on the island of Utoeya near Oslo. Officials said the attacks killed 93 people.
