RUTHFULLY YOURS

The 32 year-old appears to have quoted verbatim large sections from the preaching of Theodore Kaczynski in his 1500 page online rant.

Breivik had “copied and pasted” almost a dozen key passages from the 69 year-old’s 35,000 manifesto, only changing particular words such as “leftist” with “cultural Marxist”.

It remains unclear what his motivations were, but experts said it appeared he had taken “inspiration” from Kaczynski whose two decade parcel-bomb terror campaign killed three people and 29 injured others.

Despite meticulous university thesis-style referencing through the manifesto, Norwegian bloggers discovered that passages quoting Kaczynski were not credited.

His “martyrdom operation” diary, titled “2083: A European Declaration of Independence”, discloses that he started preparing for the attacks for nearly two years.

Breivik’s document, which calls for a Christian war to defend Europe against what he described as a Muslim domination, details his links to London over the past few years.

It was published on the internet just hours before he killed at least 93 people and wounded nearly 100 more in twin attacks in Norway.

Ragnhild Bjørnebek, a researcher on violence for the Norwegian Police Academy, described the disclosures as “very interesting” and showed startling similarities between the two terrorists.

“The Unabomber was very intelligent and who was also a person that was very difficult to detect,” she told Norwegian media.

Kaczynski plotted and carried out his deadly mail bombing spree on a 1.4-acre patch of land near Lincoln, Montana over a period of 17 years between 1978 and 1995.

The Harvard-trained mathematician, who railed against the effects of advanced technology in his manifesto, was the focus of the longest and costliest manhunt in US history before his brother tipped off police in 1996.

Government investigators called him the Unabomber because some of his attacks were directed at university scholars.

He lived as a virtual hermit, honing his survival skills, and there is no electricity or running water on the land where he lived.

He was captured there and jailed for life in May 1998, with no possibility of parole.
