Police have arrested one man on preliminary charges in the massacre and a bombing in Oslo hours earlier. NTB is reporting Saturday that witnesses told police two people were involved in the shooting on Utoya island. The agency says police are looking into it.
The agency says that the second man apparently wasn't disguised in police uniform. The man under arrest was wearing a sweater with a police emblem on it.
Foreign intelligence
Prime Minister Jens Stoltenberg said Norwegian officials are working with foreign intelligence agencies to see if there there was any international involvement in the bomb and shooting that together have killed 92 people.
"We have running contact with other countries' intelligence services," Stoltenberg said after meeting with survivors at a hotel near the scene of the island gun attack that killed 85. "Some of the investigation is under way," he said. "Some of it is obviously to.... investigate whethere there are any international connections."
Man arrested in vicinity of Norway PM with knife
Norwegian police arrested a young man carrying a knife Saturday at a hotel where Prime Minister Stoltenberg was visiting survivors of a shooting rampage that left 85 dead, broadcaster NRK said.
The suspect said he was a member of the Labour party's youth wing and that he had a knife in his pocket "because he did not feel safe," an NRK reporter said. The shooting's victims were all killed by a gunman while attending a summer camp run by the Labour party's youth wing on an island near Oslo.
Stoltenberg was inside a building when the young man was arrested outside the hotel, an AFP reporter witnessed. The young man was taken to a police car which left the scene. According to another NRK reporter, the young man, wearing shorts, did not appear threatening and "was smiling when he was put in the police car." Police could not be reached for an immediate comment on the incident.
Royals meet victims' families
Norway's King Harald, Queen Sonja and Crown Prince Haakon have arrived at Sundvollen to meet the families of victims of the youth camp shooting massacre.
The royals were greeted by Prime Minister Stoltenberg as they arrived at a hotel in the town near the Utoya island where police say a gunman posing as a police officer opened fire and killed 85 people.
Twin shooting and bomb attacks left at least 92 dead in western Europe's deadliest carnage since the 2004 Madrid bombings as a Norwegian gunman opened fire at a youth camp and a bomb tore through central Oslo.
The suspect was a 32-year-old Norwegian who posted anti-Muslim rhetoric online, police commissioner Sveinung Sponheim told the NRK television channel, but added: "It's too early to say if this was a motive behind the act."
Police voiced fears that the toll could rise as they searched for victims of the shootings at a summer school meeting organised by Prime Minister Jens Stoltenberg's ruling Labour Party on Utoeya, an island outside the capital.
Security was meanwhile tightened across potential target sites in the capital, police said Saturday, but they lifted an advisory that had urged residents to stay home.
"We have confirmation that at least 80 people are dead. We do not exclude a higher toll," police spokesman Are Frykholm told AFP, speaking of the shooting spree at the island.
Police had earlier confirmed that seven people were killed as a powerful bomb ripped through central Oslo - where the prime minister's office and several government buildings are located - and nine were critically injured.
Right-wing links
According to the TV2 channel, the arrested suspect has links to right-wing extremists and possessed two weapons registered in his name.
Prime Minister Stoltenberg said the culprits would not intimidate one of Europe's most peaceful countries.
"People have lived through a nightmare that very few of us can imagine," he said. "The coming days will show who is responsible and what kind of punishment they will get.
"The message to whoever attacked us, the message from all of Norway is that you will not destroy us, you will not destroy our democracy and our ideals for a better world."
Western leaders denounced the attacks and vowed solidarity with NATO member Norway - an enthusiastic participant in international military missions that has forces in Afghanistan and is participating in air strikes in Libya.
Stoltenberg had been due to give a speech on Saturday to the 560 people attending the youth camp on the island.
Scenes of panic and horror
Witnesses described scenes of panic and horror after the gunman, who police said was disguised as a police officer but had never worked for the police force, opened fire on the youth gathering.
"I saw a lot of people running and screaming, I ran to the nearest building and hid under a bed," Emilie Bersaas, 19, told Britain's Sky News.
"It is kind of unreal, especially in Norway... This is something we hear about happening in the US."
Another young survivor, Jorgen Benone, said: "People were hiding behind stones. I saw people being shot... I felt it was best to stay quiet, not to run into the open.
"I saw (the gunman) once just 20 to 30 metres away from me," Benone said, adding that he then swam to safety and was rescued by a boat.
Explosives feared
Norwegian police said they feared there could also be explosives on the island.
Reports of the island shooting emerged shortly after a blast tore through the government quarter in central Oslo. Police said a "bomb" had been behind the "powerful explosion".
"There are good reasons to believe that there is a link between the events," police commissioner Sponheim told reporters in Oslo.
Mayor Fabian Stang said the capital was struggling to come to terms with the idea that it had joined the list of cities targeted by bombers.
"Today we think about those people living in New York and London who have experienced this kind of thing," he told Sky.
The prime minister's office and other buildings were heavily damaged, while pavements were covered in broken glass as smoke rose above the wreckage.
A police spokesman said a vehicle had been seen driving at high speed in the area just before the explosion, but did not confirm that the blast had been caused by a car bomb.
Police had sealed off the area and urged residents to stay in their homes.
UAE condemns attacks
The UAE has strongly condemned the attacks. "The UAE condemns in the strongest possible terms these terrible, appalling crimes and expresses its full solidarity and standing with the Government of Norway in confronting these criminal acts," UAE Foreign Minister Shaikh Abdullah Bin Zayed Al Nahyan said in a statement.
UN chief Ban Ki-moon and the EU condemned the attacks and the NATO chief denounced them as "heinous".
US President Barack Obama called the attacks "a reminder that the entire international community has a stake in preventing this kind of terror from occurring."
The Norwegian capital is a well-known symbol of international peace efforts, home to the Nobel Peace Prize and the birthplace of the 1993 Israeli-Palestinian Oslo Accords.
The attacks were the worst in western Europe since the 2004 train bombings in Madrid, which left 191 dead and nearly 2,000 injured.
