Norwegian mass murderer Anders Breivik in human rights appeal case

Norwegian mass murderer Anders Behring Breivik, who killed 77 people in a bombing and shooting rampage in 2011, is returning to court this week as the government appeals against a ruling that his isolation in prison breaches the European Convention on Human Rights.

The 37-year-old right-wing extremist, who admitted to the killings that prime minister Erna Solberg called "one of the darkest days in Norwegian history," was convicted of mass murder and terrorism in 2012.
