Norwegian police said Sunday that a shooting at a mosque near Oslo is being treated as an "attempted act of terror" and that the suspected gunman harbours far-right, anti-immigrant views.
The suspect entered the mosque in the affluent Oslo suburb of Baerum on Saturday armed with multiple weapons and opened fire before being overpowered by a 65-year-old man who suffered minor injuries.
Hours after the attack, the body of a young woman was found in a home in Baerum and police on Sunday confirmed that it was the suspect's 17-year-old stepsister. Investigators launched a murder investigation into the death.
