0908: The BBC's security correspondent Gordon Corera said there were comparisons with the Oklahoma City bombing in the US in 1995. He said: "That was done largely by a single person (Timothy McVeigh) with a little bit of help from others." He said Norwegian police would want to know if the gunman had help from a network. He said: "Did he have a network or did he have military training? How did he carry out a bombing and then carry out so many killings? That does suggest some sort of experience."
0914: Norwegian Labour politician Stine Renate Haheim, 27, told BBC News what she had seen on Utoeya: "People were saying we're safe, the police are here. Then we saw a man in a police uniform and he starting shooting people one by one. We turned and ran. We were just trying to keep safe and trying to take care of each other. He was very calm. I didn't hear him speak."
0934: Via Twitter It would appear that Anders Behring Breivik, the 32-year-old suspect in the attacks, recently set up a Twitter profile. Last Sunday, the only chilling tweet from the account: "One person with a belief is equal to the force of 100,000 who have only interests."
0931: Gordon Corera says: "There are suspicions he might have posted something on a far-right neo-Nazi website. He might have expressed strongly anti-Muslim sentiments. Clearly there was some sort of political agenda. He bombed the government offices and was going for people from the governing party. The police won't confirm it but there seems to be a suggestion that he wants to explain his activities."
0939: Eskil Pedersen, leader of the Norwegian Labour youth movement, told a press conference he did not see the gunman but it dawned on him that the gunshots were a continuation of the "terrorist attack" in Oslo. He said: "It's obvious that our entire democracy has been attacked...We always look forward to it (the summer camp on Utoya) and it has meant so much to us historically. In the Labour youth movement there are 10,000 members and there are many who feel like this...This will change Norway and hopefully for the better but it's too early to say how."

0950: Eyewitness Jorgen Benone said: "The guy was dressed as a policeman and he was trying to suggest that he was kind of helping us and he said, 'Come here!'

1019: Earlier Adrian Pracon, a survivor of the Utoya attack, gave the BBC a detailed account of the incident. He said he played dead to survive and added: "He came closer, I could feel his breath, I could feel his boots, I could feel the warmth of the barrel."

We exited the cafe and the real horror sunk in as bloodied people started to stumble down into the square. I looked to a corner shop in which I had withdrawn money minutes before the blast. The ATM stood behind a large glass window and large, toothlike shards of glass were facing inwards. I hate to think what could have happened if I had been there."
1035: Lisa-Marie Husby told the BBC: "We ran to a cabin in the forest and he was running behind us. We got in the cabin and locked the door. I hid under the bed.

He shot through the door and the most terrifying part was that he was sticking a gun through the window...I hid under the bed for two hours until I knew I was safe."

I tried to save those I could, but there were people there that I couldn't do anything for."
1116: The quote: "One person with a belief is equal to the force of 100 000 who have only interests" which Breivik is reported to have posted on his Twitter account shortly before the attacks is being attributed to 19th century British philosopher John Stuart Mill, the father of utilitarianism.

This terrible event is especially heartbreaking because so many of the victims were young people."
