In his 1518-page online mission statement, the right-wing extremist behind Friday's bomb and gun rampage told how in April he leased a farm three hours north of Oslo, from a man who was going to jail.
He established a bogus agricultural company, which allowed him to obtain fertiliser, and moved to the farm to begin building explosives.
"The last week in the capital I spent a lot of time with friends, partying and attending various social events. I knew that it would be the last chance, for a very long time, I would enjoy their presence," he wrote, in excerpts published by The (London) Times.
On June 13, he prepared a test device in a remote area. "BOOM! The detonation was successful!!!:-)," he wrote.
