The man blamed for attacks on Norway's government headquarters and a youth retreat that left at least 92 dead was motivated by a desire to bring about a revolution in Norwegian society, his lawyer said today.
A manifesto that he is believed to have written ranted against Muslim immigration to Europe and vowed revenge on "indigenous Europeans" who he accused of betraying their heritage.
Although the lawyer for 32-year-old Anders Behring Breivik said his client acted alone, police conducted raids on a garage and sheds in an industrial neighbourhood of eastern Oslo, said police officer Kjell Bjerklund.
Survivors of the mass shooting on Utoya island in which at least 85 young people died reported seeing two assailants, and police have said they were looking into those accounts and had not ruled out a second suspect. Another seven people were killed in Friday's bombing in an Oslo government building.
In all, 92 people were killed and 97 wounded. There are still people missing at both scenes. Six hearses pulled up at the shore of the lake surrounding the island today, 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.
A manifesto published online on the day of the attacks - which police are looking at - ranted that the European elite, "multiculturalists" and "enablers of Islamisation" would be punished for their "treasonous acts". Police have not confirmed that Breivik wrote the document, but his lawyer referred to it and said Breivik had been working on it for years.
The treatise ends with a detailed description of the plot, ending with a note dated 12:51 p.m. on July 22: "I believe this will be my last entry."
Police and his lawyer have said that Breivik confessed to the twin attacks, but denied criminal responsibility. He has been charged with terrorism and willappear in court tomorrow.
Police Chief Sveinung Sponheim said a forensics expert from Interpol would join the investigation today.
Norway's King Harald V and his wife Queen Sonja and Prime Minister Jens Stoltenberg joined mourners at Oslo Cathedral.
The king and queen both wiped tears from their eyes during the service for "sorrow and hope".
More was coming to light today 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 Labour Party, and authorities have said Breivik held anti-Muslim views and posted on Christian fundamentalist websites.
"He wanted a change in society and, from his perspective, he needed to force through a revolution," his lawyer Geir Lippestad told public broadcaster NRK. "He wished to attack society and the structure of society."
Mr Lippestad said Breivik spent years writing the 1,500-page manifesto entitled, "2083 - A European Declaration of Independence," that police were examining. It was signed "Andrew Berwick."
The manifesto vowed revenge on those who it accused of betraying Europe.
"We, the free indigenous peoples of Europe, hereby declare a pre-emptive war on all cultural Marxist/multiculturalist elites of Western Europe. ... We know who you are, where you live and we are coming for you," the document said. "We are in the process of flagging every single multculturalist traitor in Western Europe. You will be punished for your treasonous acts against Europe and Europeans."
The use of an Anglicized pseudonym could be explained by a passage in the manifesto describing the founding, in April 2002 in London, of a group he calls a new Knights Templar. The Knights Templar was a medieval order founded to protect Christian pilgrims in the Holy Land after the First Crusade.
A 12-minute video clip posted on YouTube with the same title as the manifesto featured symbolic imagery of the Knights Templar and crusader kings as well as slides suggesting Europe is being overrun by Muslims. Police could not confirm that Breivik had posted the video, which also featured photographs of him dressed in a formal military uniform and in a wet suit pointing an assault rifle.
The video was a series of slides that accused the left in Europe of allowing Muslims to overrun the continent: One image showed the BBC's logo with the "C" changed into an Islamic crescent. Another declared that the end result of the left's actions would be an "EUSSR."
Police spokesman John Fredriksen confirmed that the essay was posted the day of the attacks. The document signalled an attack was imminent: "In order to successfully penetrate the cultural Marxist/multiculturalist media censorship, we are forced to employ significantly more brutal and breathtaking operations, which will result in casualties."
In the last 100 pages, the manifesto apparently lays out details of the author's social and personal life, including steroid use and an intention to solicit prostitutes in the days before the attack.
Witnesses at the island youth retreat described the way Breivik lured them close by saying he was a police officer before raising his weapons. People hid and fled into the water to escape the rampage; some played dead.
Police took 90 minutes from the first shot to reach the island - delayed because they did not have quick access to a helicopter and struggled to find a boat once they reached the lake. Breivik surrendered when they reached him.
Divers continued to comb the lake waters around the island where some 600 young people were attending a Labour Party summer retreat when it came under attack, amid fears people may have drowned while trying to swim to safety.
Police said the bomb used in the Oslo blast was a mixture of fertiliser and fuel used to blow up a federal building in the US in 1995. A farm supply store said they had alerted police that Breivik bought six metric tons of fertiliser, which can be used in homemade bombs.
