OSLO, Norway (AP) -- The man blamed for the terrorist attacks on Norway's government headquarters and an island retreat for young people that left at least 93 dead was motivated by a desire to bring about a revolution in Norwegian society, his lawyer said Sunday.
A manifesto he published online -- which police are poring over and said was posted the day of the attack -- ranted against Muslim immigration to Europe and vowed revenge on "indigenous Europeans," whom he accused of betraying their heritage. It said that they would be punished for their "treasonous acts."
The lawyer for the 32-year-old Norwegian suspect, Anders Behring Breivik, said Sunday that his client wrote the document alone. While police said they were investigating reports of a second assailant on the island, the lawyer said Breivik claims also claims no one helped him.
The treatise detailed plans to acquire firearms and explosives, and even appeared to describe a test explosion: "BOOM! The detonation was successful!!!" It ends with a note dated 12:51 p.m. on July 22: "I believe this will be my last entry."
That day, a bomb killed seven people in downtown Oslo and, hours later, a gunman opened fire on dozens of young people at a retreat on Utoya island. Police said Sunday that the death toll in the shooting rose to 86.
That brings the number of fatalities to 93, with more than 90 wounded. There are still people missing at both scenes. Police have not released the names of any of the victims.
Police said Sunday that a police officer had been hired to provide security on the island on his own time. It was not clear who hired him or if he was on the island at the time of the attacks.
Dr. Colin Poole, head of surgery at Ringriket Hospital in Honefoss northwest of Oslo, told The Associated Press the gunman used special bullets designed to disintegrate inside the body and cause maximum internal damage. Poole said surgeons treating 16 gunshot victims have recovered no full bullets.
"These bullets more or less exploded inside the body," Poole said. "It's caused us all kinds of extra problems in dealing with the wounds they cause, with very strange trajectories."
Ballistics experts say the so-called dum-dum bullets also are lighter in weight and can be fired with greater accuracy over varying distances. They commonly are used by air marshals and hunters of small animals.
Six hearses pulled up at the shore of the lake surrounding the island on Sunday, as rescuers on boats continued to search for bodies in the water. Body parts remain inside the Oslo building, which housed the prime minister's office. In a chilling allusion to the fact that the tragedy could have even been greater, police said Sunday that Breivik still had "a considerable amount" of ammunition for both his guns -- a pistol and an automatic weapon -- when he surrendered.
Police and his lawyer have said that Breivik confessed to the twin attacks, but denied criminal responsibility for a day that shook peaceful Norway to its core and was the deadliest ever in peacetime. Breivik has been charged with terrorism and will be arraigned on Monday. Geir Lippestad, Breivik's lawyer, said his client has asked for an open court hearing "because he wants to explain himself."
Police Chief Sveinung Sponheim said a forensics expert from Interpol would join the investigation on Sunday.
European security officials said Sunday they were aware of increased Internet chatter from individuals claiming they belonged to the Knights Templar group that Breivik refers to in the manifesto. They said they were still investigating claims that Breivik, and other far-right individuals, attended a London meeting of the group in 2002. The two officials spoke on condition of anonymity because they were not authorized to speak about the investigation.
The officials would also not immediately confirm that they had been aware of Breivik as a potential threat.
As authorities pursued the suspect's motives, Oslo mourned the victims. Norway's King Harald V and his wife Queen Sonja and Prime Minister Jens Stoltenberg crowded into Oslo Cathedral, where the pews were packed, and people spilled into the plaza outside the building. The area was strewn with flowers and candles, and people who could not fit in the grand church huddled under umbrellas in a drizzle.
The king and queen both wiped tears from their eyes during the service for "sorrow and hope."
Afterward, people sobbed and hugged one another in the streets, as many lingered over the memorial of flowers and candles. The royal couple and prime minister later visited the site of the bombing in Oslo.
More was coming to light Sunday about the man who police say confessed to a car bomb at government headquarters in Oslo and then, hours later, opening fire on young people at an island political retreat.
Both targets were linked to Norway's left-leaning Labor Party. Breivik's manifesto pillories the political correctness of liberals and warns that their work will end in the colonization
