A spectator evicted Friday from a court in Oslo after throwing a shoe at accused gunman Anders Behring Breivik said his action was intended "to send a message" to the defendant.
"I had to send the killer a message from all those whose lives he has destroyed. He is a murderer, a terrorist," Hayder Mustafa Qasim, a Kurd from northern Iraq, was quoted as telling the online edition of the Aftenposten daily.
Qasim's younger brother, Karar Mustafa Qasim, 18, was one of the 69 who died in a shooting at a Labor Party youth camp last year. He was hit by four shots.
Throwing shoes is a form of insult and protest in several parts of the world since the soles of shoes are considered unclean.
Qasim's outburst took place just as the final autopsy report was due to be read out. He was evicted from the public gallery after shouting "You killer! You killed my brother! Go to hell!" at Breivik.
Breivik has admitted to having carried out the July 22, 2011, twin attacks in Oslo and Utoya that claimed a total of 77 lives, but has pleaded not guilty.
The Oslo District Court late Friday said it would not allow footage of the incident to be broadcast, rejecting an appeal from several media organizations.
Some members in the public gallery applauded the shoe-throwing while others started to cry, apparently shocked by Qasim's shouts.
The shoe missed Breivik but hit his defense attorney, Vibeke Hein Baera, who said she suffered no harm. Baera said she hoped the proceedings would continue to be conducted in a dignified manner despite the difficult accounts presented in court.
It was not known if Qasim would face any repercussions over the incident.
"I took off my shoe, got up, shouted at the killer, got eye contact with him and threw the shoe," Qasim was quoted as saying by the Norwegian newspaper Aftenposten.
"He was alone in Norway, without family," Qasim said of his brother. "The killer took his life. And he ruined the life for me and the family. I have traveled from Iraq to Norway to be in court. And it has made an enormous impression on me."
Breivik smiled and appeared to be unruffled, remarking when the court reconvened: "If anyone wants to throw anything at me, do so when I enter or leave the court," according to reporters present. "Don't throw things at my attorneys."
Breivik has admitted to the attacks but pleaded innocent to terror charges, saying the victims were traitors for embracing multiculturalism. He claims to represent a European network of modern-day crusaders opposed to Muslim immigration, but prosecutors say the group does not exist.
