Adrian Pracon says he played dead to try to avoid the gunman on Utoeya
Norwegians are mourning the victims of a massacre at an island youth camp and a bombing in the capital Oslo.
At least 85 people died when a gunman opened fire at the Utoeya camp on Friday, hours after a blast in the government quarter killed seven.
Prime Minister Jens Stoltenberg has comforted relatives of victims alongside the Norwegian king and warned there could be yet more casualties.
A 32-year-old Norwegian man has been charged over both attacks.
Many people were still looking for their children and had not so far been able to locate them, PM Stoltenberg said after meeting victims and relatives with King Harald, Queen Sonja and Crown Prince Haakon in the town of Sundvollen near the island.
Mr Stoltenberg said he was "deeply touched" by the meetings. "We will do whatever we can to give them as much support as possible," he said.
Earlier he said that he was due to have been on Utoeya - "a youth paradise turned into a hell" - a few hours after the attack took place.
The suspect is reported by local media to have had links with right-wing extremists. He has been named as Anders Behring Breivik. Police searched his Oslo apartment overnight and are questioning him.
A farm supply firm has confirmed selling six tonnes of fertiliser to Mr Breivik who is reported to have run a farming company. Speculation has been rife that fertiliser could have been used in the Oslo bomb.
'Christian fundamentalist'
Police say they are investigating whether the attacks were the work of one man or whether others helped.
"At Utoeya, the water is still being searched for more victims," deputy police chief Roger Andresen told reporters.
"We have no more information than... what has been found on [his] own websites, which is that it goes towards the right and that it is, so to speak, Christian fundamentalist."
The BBC's Richard Galpin, near the island which is currently cordoned off by police, says that Norway has had problems with neo-Nazi groups in the past but the assumption was that such groups had been largely eliminated and did not pose a significant threat.
Local media report that police are investigating claims by witnesses that a second person was involved, apparently not disguised in a police uniform.
The number killed in the island shooting spree, which is among the world's most deadly, had been put at 10 on Friday - but soared overnight. Hundreds of young people had been attending the summer camp organised by the governing Labour Party on Utoeya island.
Eyewitnesses described how a tall, blond man dressed as a policeman opened fire indiscriminately, prompting camp attendees to jump into the water to try to escape the hail of bullets.
Some of the teenagers were shot at as they tried to swim to safety.
Armed police were deployed to the island but details of the operation to capture the suspect remain unclear. After his arrest he was charged with committing acts of terrorism.
Police say they discovered many more victims after searching the area around the island. They have warned the death toll may rise further as rescue teams continue to scour the waters around the island.
The gunman is reported to have been armed with a handgun, an automatic weapon and a shotgun.
NRK journalist Ole Torp told the BBC he went to the island dressed in a police uniform, asked people to gather round and then started shooting.
The attacks sparked strong international condemnation, with US President Barack Obama expressing his condolences and offering support.
Britain's Queen Elizabeth II spoke of her shock and sadness in a letter to King Harald.
The BBC's John Sopel in Oslo says the city is strangely quiet and there is a heavy military presence, with checkpoints around the government quarter.
Officials have urged people to stay at home and avoid central areas of the city.
