Hackering group Anonymous have hijacked Norway mass murderer Anders Behring Breivik's Twitter account.

Initially the tweets appeared to come from Breivik himself.

One tweet said: “This Twitter account has been seized by #NORIA. @AnonymousNorway."

“We want Anders to be forgotten. Labels like ‘monster’ or ‘maniac’ won’t do either,” read another.

“Media should call him pathetic; a nothing. #Forgethim.”

The Twitter page was created a few days before Breivik carried out his devastating attack in Norway, during which he killed more than 90 young people.

Since then, all tweets have been deleted except one quote from philosopher John Stuart Mill: “One person with a belief is equal to the force of 100,000 who have only interests.”

Breivik carried out the Norway killings in a bid to promote his 1516-page racist manifesto.

Anonymous wants to find the manifesto and "add stupid stuff, remove parts, shoop his picture" to "let Anders become a joke, such that nobody will take him serious anymore".
