OSLO: Norwegian police on Sunday confirmed that a 1,500-page violent anti-Islamic manifesto was published by Anders Behring Breivik on Friday just hours before he killed at least 93 people.
The online book describes the planning, explosives making and violent philosophy that lead to the bombing in downtown Oslo and shootings at a Labour youth camp nearby.
"This manifesto was published on the day of the events," Oslo's acting police chief Sveinung Sponheim told a news conference. "We have confirmation of that."
The killings would draw attention to the manifesto, called "2083-A European Declaration of Independence", Breivik wrote.
"Once you decide to strike, it is better to kill too many than not enough, or you risk reducing the desired ideological impact of the strike," he wrote.
He also attacked "the Islamic colonisation and Islamisation of Western Europe" and "rise of cultural Marxism/multiculturalism".
"He wishes to change society," Breivik's lawyer Geir Lippestad told public broadcaster NRK.
The lawyer earlier said that his client "believed the actions were atrocious, but that in his head they were necessary."
The lawyer also said that his client wanted to explain himself in court on Monday.
Suspect's father in shock
The father of the young man suspected of single-handedly killing 93 people in Norway's worst post-war tragedy told the Verdens Gang newspaper he was in a state of shock.
"I was reading the news on the Internet and suddenly I saw his name and picture," Anders Behring Breivik's retired father told the Norwegian paper.
"I am in a state of shock, it's absolutely horrific to hear that," said Jens Breivik, who currently lives in France.
He said he knew nothing of his son's plans and explained he had not had contact with him since 1995.
"We never lived together but we had some contact during his childhood," he said. "When he was younger, he was an ordinary boy but not very communicative. He was not interested in politics at the time."
The 32-year-old was arrested following the twin attacks which left 93 people dead on Friday and sent shockwaves through the usually peaceful country.
The suspect confessed to perpetrating a car bomb against Oslo's government quarters and going on a shooting spree during a Labour Party summer camp on a nearby island.
Breivik, who described in a manifesto released on the Internet how he planned the attacks over years, told police he acted alone in what would be one of the worst acts of violence by a single man in recent memory.
