Jailed Norwegian mass murderer Anders Behring Breivik has given a Nazi salute at the start of a court case against Norway at which his lawyers argued he is receiving inhuman treatment.
Breivik killed 77 people in 2011 by bombing central Oslo and then going on a shooting spree at the summer camp of the left-wing Labor Party's youth organization on the island of Utoya.
The March 15 hearing marked Breivik's first public appearance since he was sentenced to 21 years in prison in 2012.
He entered the court, shook hands with his lawyers, and made the Nazi salute after police removed his handcuffs.
Breivik, 37, is mainly challenging the government over his solitary confinement, accusing it of breaching two clauses of the European Convention on Human Rights.
The attorney general's office rejects this.
Breivik is expected to testify on March 16.
