Translated from Dutch NOS TV:
Perpetrator of attack on Norwegian mosque posted his nazi sympathies online
The Norwegian police are investigating the attack on a mosque yesterday as an act of terror. The 20-year-old attacker has right-wing extremist ideas. According to the police, he expressed his sympathy online for Vidkun Quisling, the nazi prime minister of Norway during the Second World War.
Yesterday afternoon, just after four o’clock, the man invaded the Al-Noor mosque in Bærum, near Oslo. He fired four shots. A man was slightly injured. … The shooter was overpowered by 65-year-old mosque goer Mohamed Rafiq, writes the Norwegian newspaper Aftenposten.

After the attack, a dead woman was found in the suspect’s apartment. The police did not want to say who the woman is and what happened. The woman was, however, a “close acquaintance” of the suspect. The police suspect the man of murder. He has not been questioned yet.
Before the attack, the man is said to have have announced his act on the small online forum Endchan. He also wanted the attack to be streamed live on Facebook, but that didn’t work. The man said he was inspired by the perpetrator of the racist attack on two mosques in Christchurch, New Zealand, where 51 people died. He placed his extreme right-wing manifesto on the similar forum 8chan, known as a “cradle of hatred”.
The perpetrator of the racist attack in El Paso last weekend (22 dead) also placed his extreme right-wing manifesto on 8chan. That site then went offline, because the companies that kept the site up no longer wanted to cooperate with it. It was expected that users would go to other, comparable platforms. Endchan is now also offline.
Endchan claims the site will return.
