The man suspected of a gun and bomb attack in Norway has called his deeds atrocious yet necessary, his defence lawyer said.
"He has said that he believed the actions were atrocious, but that in his head they were necessary," defence lawyer Geir Lippestad told TV2 news on Saturday.
Lippestad said his client had said he was willing to explain himself in a court hearing on Monday. The court will decide at the hearing whether to keep the suspect in detention pending trial.
Earlier on Saturday, officials in Norway had charged a 32-year-old Norwegian man with killing at least 92 people in a gun and bomb attack described as the worst act of violence in the country since World War II.
Police confirmed to Al Jazeera on Saturday that the suspect had been named as Anders Behring Breivik.
Breivik, who confessed to firing weapons during questioning on Saturday, belonged to right-wing political groups. But officials said they are not jumping to conclusions about his motives.
Reports suggest he belonged to an anti-immigration party, wrote blogs attacking multi-culturalism and was a member of a neo-Nazi online forum.
But Norwegian authorities said Breivik, detained by police after 85 people were gunned down at a youth camp and another 7 killed in an Oslo bomb attack on Friday, was previously unknown to them and his internet activity traced so far included no calls to violence.
Breivik bought six tonnes of fertiliser before the massacre, a supplier said on Saturday, as police investigated witness accounts of a second shooter in the attack on Utoya.

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.
The shooting spree began just hours after a massive explosion that ripped through an Oslo high-rise building housing the prime minister's office.
"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," Norwegian Prime Minister Jens Stoltenberg told reporters on Saturday.
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 35km northwest of Oslo, is organised by the party's youth wing, and the prime minister had been scheduled to speak there on Saturday.
'Christian fundamentalist' views
The blond-haired Behring Breivik described himself on his Facebook page as "conservative", "Christian", and interested in hunting and computer games like World of Warcraft and Modern Warfare 2, reports say.
On his Twitter account, he posted only one message, dated July 17, in English based on a quote from British philosopher John Stuart Mill: "One person with a belief is equal to a force of 100,000 who have only interests".
The suspect was reportedly also a member of a Swedish neo-Nazi internet forum, a group monitoring far-right activity said on Saturday.
Nordisk, a 22,000-member web forum founded in 2007, describes itself as a portal on the theme of "the Nordic identity, culture and traditions."
In comments from 2009-2010 to other people's articles on another website, Document, which calls itself critical of Islam, Breivik criticised European policies of trying to accommodate the cultures of different ethnic groups.
"When did multi-culturalism cease to be an ideology designed to deconstruct European culture, traditions, identity and nation-states?" said one his entries, posted on February 2, 2010.

Breivik wrote he was a backer of the "Vienna School of Thought", which was against multi-culturalism and the spread of Islam.
He also wrote he admired Geert Wilders, the populist anti-Islam Dutch politician, for following that school. Wilders said in a statement on Saturday: "I despise everything he stands for and everything he did".
Nina Hjerpset-Ostlie, a contributing journalist to the right-wing website, said she had met Breivik at a meeting in late 2009.
"The only thing we noticed about him is that he seemed like anyone else and that he had some very high-flying, unrealistic, ideas about marketing of our website," she said.
Police searched an apartment in an Oslo suburb on Friday, which neighbours said belonged to Breivik's mother.
"It is the mother who lives there. She is a very polite lady, pleasant and very friendly," said Hemet Noaman, 27, an accounting consultant who lives in the same building in a wealthy part of town. "He often came to visit his mother but did not live here."
Oslo Deputy Police Chief Roger Andresen would not speculate on the motives for what was believed to be the deadliest attack by a lone gunman anywhere in modern times.
"He has never been under surveillance and he has never been arrested," Andresen told a news conference on Saturday.
Populist party member
Breivik, who attended a middle class high school called Handelsgym in central Oslo, had also been a member of the Progress Party, the second-largest in parliament, the party's head of communications Fredrik Farber said.
He was a member from 2004 to 2006 and in its youth party from 1997 to 2007.
The Progress Party - conservative but within the political mainstream - wants far tighter restrictions on immigration, whereas the centre-left government backs multi-culturalism. The party leads some public opinion polls.
A politician who met Breivik in 2002-2003, when he was apparently interested in local Oslo politics, said he did not attract attention.
"I got the impression that he was a modest person ... he was well dressed, it seemed like he was well educated," Joeran Kallmyr, 33, an Oslo municipality politician representing the Progress Party, told the Reuters news agency.
Progress leader Siv Jensen stressed he had left the party.
Breivik was also a freemason, said a spokesman for the organisation.
