Anders Behring Breivik, the suspect in Friday's massacre in Norway that left 92 dead, has admitted responsibility, his lawyer has told Norway's NRK television channel, the AFP reports.

"He admitted responsibility," lawyer Geir Lippestad told the television station on Saturday.

"He explained that it was cruel but that he had to go through with these acts," Lippestad said, adding that the attacks were "apparently planned over a long period of time".

The Associated Press adds:

"He has confessed to the factual circumstances," Breivik's defense lawyer, Geir Lippestad, told public broadcaster NRK. Lippestad said his client had also made some comments about his motives.

"He's said some things about that but I don't want to talk about it now," the lawyer told NRK.

Information about Breivik's motivations have been emerging throughout the day. Apparently, Breivik uploaded a video on YouTube six hours before the bomb in the center of Oslo went off, according to TV2, the Wall Street Journal reports. The video was uploaded by a user called AndrewBerwick on YouTube, and calls for conservatives to "embrace martyrdom."

"[If] the multiculturalist elites of Europe continue to refuse to voluntarily transfer political and military power to our conservative revolutionary forces ... then [the second world war] is likely going to appear as a picnic compared to the coming carnage," the video stated in captions. The video has since been removed from YouTube, but a supposed copy is posted below (note, we cannot confirm this is in fact the video). Pictures that appear at the end of the approximately 12-minute video, called "Knights Templar 2083," also appeared on Breivik's now closed Facebook page, Reuters reports. However, Reuters likewise adds that "it was not possible to verify who uploaded the video, which was posted on July 22 by an Andrew Berwick."

A Norwegian discussion website, www.freak.no, also had a link to a 1,500-page book called "2083 - A European Declaration of Independence" that contained similar text. The Journal reports that it was likewise signed by an AndrewBerwick, which is supposedly an English translation of the name Anders Breivik. The manifesto is a description of Breivik's "background and political viewpoints."

Mother Jones has also posted English translations of Breivik's entries at the anti-Muslim website called Document.no. He argues for setting up a system of social networking "such that is linked to similar organizations in other countries (similar to a beginning of a cultural Euro-version of a Tea Party movement)."

Here are some additional excerpts from his comments against multi-culturalism and Islam:

Tell me one country where Muslims have lived peacefully with non-Muslims without the Jihad

...How many thousands of new Europeans must die, how many one hundred thousand European women should be raped, millions robbed and tractor discarded before you understand that  multiculturalism + Islam does not work?

Further, he writes on behalf of Norwegian children, despite admitting to attacking the Youth Camp:

I dare not even think of how many Norwegian children who have been suicide because of these experiences (assault, robbery, rape, psychological terror committed by Muslim youths). There are probably several hundred in the last 15 years.

....Non-Muslim youth in Oslo aged 12-18 are in a particularly vulnerable situation in terms of harassment [from] Muslim youth.
