SUNDVOLLEN, Norway (AP) — The Norwegian man suspected in a bombing and shooting spree that killed at least 92 people bought six tons of fertilizer before the massacre, the supplier said Saturday as police investigated witness accounts of a second shooter.
Norway's royal family and prime minister led the nation in mourning, visiting grieving relatives of the scores of youth gunned down at an island retreat, as the shell-shocked Nordic nation was gripped by reports that the gunman may not have acted alone.
Downtown Oslo was a sea of roadblocks Saturday, with groups of people peering over the barricades wherever they sprang up. But evacuations of an area of the city just blocks from the bombing site Saturday evening were quickly halted.
The shooting spree began just hours after a massive explosion that ripped through an Oslo high-rise building housing the prime minister's office. At least 92 people have been killed, but police say more are missing.
The suspect in custory was identified by Norway's national broadcaster as Anders Behring Breivik, 32; police would not confirm his identity because he has not been formally charged.
Authorities say he posted on Christian fundamentalist websites and reportedly held right-wing, anti-Muslim views. He was also once a member of the youth wing of a rightist party.
The queen and the prime minister hugged when they arrived at the hotel where families are waiting to identify the bodies. Both king and queen shook hands with mourners, while the prime minister, his voice trembling, told reporters of the harrowing stories survivors had recounted to him.
A man who said he was carrying a knife was detained by police officers outside the hotel. He told reporters as he was led away that he was carrying the weapon because he didn't feel safe.
On the island of Utoya, panicked teens attending a Labour Party youth wing summer camp plunged into the water or played dead to avoid the assailant in the assault that may have lasted 30 minutes before a SWAT team arrived, police said. A picture sent out on Twitter showed a blurry figure in dark clothing pointing a gun into the water, with bodies all around him.
Prime Minister Jens Stoltenberg said the twin attacks made Friday peacetime Norway's deadliest day.
Buildings around the capital lowered their flags to half-staff on Saturday. People streamed to Oslo Cathedral to light candles and lay flowers; outside, mourners began building a makeshift altar from dug-up cobblestones. The Army patrolled the streets of the capital, a highly unusual sight for this normally placid country.
"This is beyond comprehension. It's a nightmare. It's a nightmare for those who have been killed, for their mothers and fathers, family and friends," Stoltenberg told reporters earlier Saturday.
Information about the man in custody began to trickle out Saturday, including that he owned a farm and had amassed six tons of fertilizer in the weeks before the twin attacks. Fertilizer is highly explosive and can be used in homemade bombs. Police searched both the farm and his apartment in Oslo overnight.
Oddny Estenstad, a spokeswoman for agricultural material supplier Felleskjopet, said Saturday that the company alerted police to the purchase after the man emerged as a suspect.
While his motive was unclear, there were links to political activity. Mazyar Keshvari, a spokesman for Norway's rightist populist Progress Party — which is conservative but within the political mainstream — said that the suspect was a paying member of the party's youth wing from 1999 to 2004.
That quantity of fertilizer — akin to 200 50-pound bags of grain — wouldn't have fit in one car, according to Bob Ayers, former U.S. intelligence official. Two burned-out cars could be see at the scene Friday, but police have not confirmed whether they were used in the attack.
Though police have not confirmed the suspect's identity, a picture of the blonde-haired, blue-eyed man floated around the Internet. The father of three children who survived the attack said the man in the picture was the assailant.
Foreign Minister Jonas Gahr Stoere told reporters that the attacks, believed to be the work of a man who has posted on Christian fundamentalist websites, showed you can't jump to conclusions about terror acts. He said most of the political violence that Norway has seen has come from the extreme right.
"This is a phenomenon that we have to address very seriously," Stoere said.
The Army patrols were an indication of the stepped up vigilance, although police lifted their recommendation, issued after the bombing, that people stay away from the city center.
Gun violence is rare in Norway, where the average policeman patrolling in the streets doesn't carry a firearm. Reports that the assailant was motivated by political ideology was shocking to many Norwegians, who pride themselves on the openness of their society. Indeed, Norway is almost synonymous with the kind of free expression being exercised by the youth at the political retreat.
Stoltenberg vowed that the attack would not change those fundamental values.
"It's a society where young people can ... have controversial opinions without being afraid," he told reporters.
Andresen, the acting police chief, said the suspect was talking to police.
"He is clear on the point that he wants to explain himself," he told reporters at a news conference.
The toll in the shooting hit 85 on Saturday, but police warned that it could rise further as they sent divers into the lake around the island retreat to look for bodies. Acting Police Chief Roger Andresen said he did not how many people were still missing.
The Oslo University hospital said it has so far received 11 wounded from the bombing and 16 people from the camp shooting.
The carnage began Friday afternoon in Oslo, when a bomb rocked the heart of Norway. About two hours later, the shootings began at a retreat for ruling Labour Party's youth-wing, according to a police official. The official spoke on condition of anonymity because that information had not been officially released by Norway's police. The gunman used both automatic weapons and handguns, he said. It was not clear Saturday whether experts had succeeded in disarming a bomb that the official said had been left unexploded.
The blast in Oslo, Norway's capital and the city where the Nobel Peace Prize is awarded, left a square covered in twisted metal, shattered glass and documents expelled from surrounding buildings.
The dust-clogged scene after the blast reminded one visitor from New York of Sept. 11. People were "just covered in rubble," walking through "a fog of debris," said Ian Dutton, who was in a nearby hotel.
While survivors evacuated the buildings, including ones that house other government offices and Norway's leading newspaper, word came that someone had opened fire on an island about 20 miles (35 kilometers) northwest of Oslo.
Stoltenberg told reporters that he had spent every summer since 1974 on Utoya — "my childhood paradise that yesterday was transformed into hell." The island hosts retreats for the youth wing of his party.
A SWAT team that had been put on alert after the bombing was dispatched to the island once the shooting began. Police official Johan Fredriksen said that means they may have taken 30 minutes to reach the island.
Survivors described a scene there of terror. Several people fled into the water to escape the rampage, and police said they were still searching the lake for bodies.
Asked whether all victims at Utoya died from gunshot wounds or if some had drowned, Stoere, the foreign minister, said "you will likely see a combination."
A 15-year-old camper named Elise who was on Utoya said she heard gunshots, but then saw a police officer and thought she was safe. Then he started shooting people right before her eyes.
"I saw many dead people," said Elise, whose father, Vidar Myhre, didn't want her to disclose her last name. "He first shot people on the island. Afterward he started shooting people in the water."
Elise said she hid behind the same rock that the killer was standing on. "I could hear his breathing from the top of the rock," she said.
She said it was impossible to say how many minutes passed while she was waiting for him to stop.
At a hotel in the village of Sundvollen, where survivors of the shooting were taken, 21-year-old Dana Berzingi wore pants stained with blood. He said the fake police officer ordered people to come closer, then pulled weapons and ammunition from a bag and started shooting.
Several victims "had pretended they were dead to survive," Berzingi said. But after shooting the victims with one gun, the gunman shot them again in the head with a shotgun, he said.
"I lost several friends," said Berzingi, who used the cell phone of one of those friends to call police.
An official, who spoke on condition of anonymity, said the attack "is probably more Norway's Oklahoma City than it is Norway's World Trade Center." Domestic terrorists carried out the 1995 attack on a federal building in Oklahoma City, while foreign terrorists were responsible for the Sept. 11, 2001 attacks.
Though the prime minister cautioned against jumping to conclusions about the gunman's motives, both attacks were in areas connected to the left-leaning Labour Party, which leads a coalition government. The youth camp, about 20 miles (35 kilometers) northwest of Oslo, is organized by the party's youth wing, and the prime minister had been scheduled to speak there Saturday.
Sponheim said a man was arrested in the shooting, and the suspect had been observed in Oslo before the explosion there. But he refused to confirm the suspect's identity as reported by Norwegian media.
Sponheim said the camp shooter "wore a sweater with a police sign on it. I can confirm that he wasn't a police employee and never has been."
Aerial images broadcast by Norway's TV2 showed members of a SWAT team dressed in black arriving at the island in boats and running up the dock. People who had stripped down to their underwear moved in the opposite direction, swimming away from the island toward the mainland, some using flotation devices.
The United States, European Union, NATO and the U.K., all quickly condemned the bombing, which Britain's Foreign Secretary William Hague called "horrific" and NATO Secretary-General Anders Fogh Rasmussen deemed a "heinous act."
"It's a reminder that the entire international community has a stake in preventing this kind of terror from occurring," President Barack Obama said.
Obama extended his condolences to Norway's people and offered U.S. assistance with the investigation. He said he remembered how warmly Norwegians treated him in Oslo when he accepted the Nobel Peace Prize in 2009.
Britain's Queen Elizabeth II wrote to Norway's King Harald to offer her condolences and express her shock and sadness at the shooting attacks in his country.
A U.S. counterterrorism official said the United States knew of no links to terrorist groups and early indications were the attack was domestic. The official spoke on condition of anonymity because the investigation was being handled by Norway.
