A human rights court case that mass-murderer Anders Behring Breivik has brought against Norway will be heard from his prison, it has been ruled.

Since he was jailed in 2012, he has been complaining of mistreatment by the state and he likens his prison conditions to torture. He has complained repeatedly about being held in isolation, which he argues is a violation of his human rights.

The case had been scheduled to take place between 15 to 18 March this year will be heard at Skien prison as moving him to a courtroom poses security issues.

Breivik killed 77 people in a horrific bombing and shooting spree in 2011 because he was opposed to Norway's multiculturalism on 22 July 2011.

Breivik executed 69 people, mostly teenagers, at a Labour youth camp on Utoya Island and exploded a bomb outside a government building in Oslo killing eight.

In September last year he threatened to go on hunger strike complaining that he has spent too much time in isolating conditions meaning he could not complete his political science course at University of Oslo.

Brevik previously threatened to go on hunger strike in 2014 - if the prison did not update the PlayStation 2 games console with a PlayStation 3 and demanded he be allowed to choose "more adult games" to play.

Breivik was jailed for 21 years in August 2012 but his term can be extended if he is deemed to be a danger to society.

He is the only prisoner in Norway serving his sentence in long-term isolation in a nation with one of the lowest prison populations per person in the world. The neo-Nazi sympathiser was originally jailed at Ila prison, near Oslo.

The date for the case had already been established but lawyers had raised concerns about security in transferring the 36-year-old from Skien prison where he is based and the court room in Oslo. "Practical considerations and security issues justify that the case be heard at the Skien prison [about 62 miles south-west of Oslo]," the Oslo district court ruled on Monday, according to the Guardian.

In a report published in November 2015, Norway's parliamentary ombudsman said that his time on solitary confinement risks turning into "inhumane treatment".

In December 2014 staff at the prison revealed that they had confiscated more than 200 letters penned by Breivik, which reportedly detail his wish to be leader of a new extremist movement.
