Norway has not violated mass killer Anders Breivik's human rights, an appeal court has ruled.
Breivik claimed he had been abused for being placed in near-isolation in a three-room cell since he was jailed for massacring 77 people in 2011.
The Borgarting appeals court overturned a 2016 verdict by a lower Oslo court that his isolation amounted to "inhuman and degrading treatment" under the European Convention on Human Rights.
"The Borgarting Court of Appeal has determined that Anders Behring Breivik is not, and has not been subjected to torture or inhuman or degrading treatment," the court said in a statement.
Strict conditions for Breivik, who has no contact with other inmates and has not repented for the attacks, were justified because there was a "high risk" that he would use violence in future and because other prisoners might attack him, it said
Breivik's lawyer Oeystein Storrvik expressed surprise at the verdict and said he would appeal to Norway's Supreme Court. If that fails, Breivik can appeal to the European Court of Human Rights.
On 22 July 2011, Breivik set off a bomb in Oslo's government district before carrying out a mass shooting at the annual summer camp of the left-wing Labour Party's youth organisation.
