22-year-old Norwegian Philp Manshaus suspected of killing his stepsister and then storming into an Oslo mosque with firearms has been charged with murder and terror.

He had worn a helmet with a video camera attached and a bulletproof vest and had “the intention to kill as many Muslims as possible”.

Prosecution said that in August 2019 Manshaus first killed his 17-year-old stepsister, Johanne Zhangjia Ihle-Hansen, by shooting her four times with a hunting rifle. She fatally received three bullets in the head and one in the chest at their home in the Oslo suburb of Baerum.

Shortly after that, Manshaus drove to the nearby Al-Noor Islamic Centre mosque where men were preparing for Eid al-Adha celebrations.

Inside, he fired six shots but did not hit anyone before he was overpowered by one of the men – Muhammed Rafiq, who was in the mosque at the time. Men from the mosque held him down until police arrived.

He appeared in court Monday 17th February with a smirk on his face as evidence grew that he sought to emulate attacks by white supremacists in the United States and New Zealand.

A trial is scheduled to start on 7th May in Oslo.
