Norwegian Prime Minister Mr Jens Stoltenberg has confirmed that some members of the administration have died in the city centre bomb blast. Speaking at a news conference today, Mr Stoltenberg called the bombing and the shooting a nightmare. He said many people were still waiting for news of their loved ones. At least 80 people are now known to have been killed in a shooting on Friday at a youth camp on the island of Utoya near the capital Oslo. The Police say many others have been injured and the search for victims is continuing. Hundreds of people were attending a summer camp organised by the governing Labour Party when a gunman dressed as a police officer opened fire indiscriminately. Two hours before the attack on Utoya, a bomb in the centre of Oslo killed seven people ripping through government buildings. The Police are questioning a 32-year old ethnic Norwegian man in connection with both incidents. They say he has no known links to Islamist groups.
