Accused mass murderer abused his rights with Nazi salute, Norway argues

Government lawyers have accused mass killer Anders Behring Breivik of abusing the country's rule of law as a four-day trial over his prison conditions closes in Norway.

The 37-year-old right-wing extremist, who killed 77 people in bomb-and-gun attacks in 2011, wants to communicate with sympathizers and sued the government for violating his human rights by holding him in solitary confinement.

Breivik's lawyer Oystein Storrvik urged the judge Friday to look beyond the brutality of his crimes and focus on whether his treatment in prison is legal.

Government lawyer Adele Matheson Mestad said Breivik's rights haven't been violated and that he misused his rights under Norway's justice system by entering the courtroom with a Nazi salute.

The verdict is expected in April or May.
