A Norwegian white supremacist who killed his stepsister and then stormed an Oslo mosque has been sentenced to 21 years in prison, the longest jail term allowed under Norwegian law.
Philip Manshaus, who pleaded not guilty but said in court that he regretted not having caused more damage, "has proven to be an extremely dangerous person", prosecutor Johan Oeverberg said as he demanded the maximum penalty.
Last year, Manshaus, 22, killed his 17-year-old stepsister by shooting her four times with a hunting rifle at their home in the Oslo suburb of Baerum.
Then he drove to a nearby mosque where three men were preparing for Eid al-Adha celebrations.
Manshaus fired four shots from a rifle at the mosque's glass door before he was overpowered by one of the men in the mosque.
In court, Manshaus confessed to the acts but called them "emergency justice".
One man was slightly injured when overpowering Manshaus.

Judge Annika Lindstroem, of the Oslo District Court, said Manshaus had plans to kill as many people as possible and set the mosque on fire.
She said Manshaus believed that "Europe is under attack from people of ethnic origin other than his own" and that "the white race is on the brink of extinction".
The judge said Manshaus was inspired by shootings in March 2019 in New Zealand, where a gunman targeted two mosques, killing 51 people, and in August 2019 in El Paso, Texas, where an assailant targeted Hispanics and left at least 22 dead.
