The suspected gunman in an attack on a mosque in Norway over the weekend was inspired by the Christchurch shooting in New Zealand and two recent mass shootings in the U.S., according to online posts analyzed by The Guardian.

Philip Manshaus, 21, reportedly stormed a mosque in Baerum, a town near Oslo, on Saturday. He was restrained by worshippers and no one was killed.

Police are investigating the shooting as a potential terror attack, per The Guardian.

In a post on the day of the shooting, Manshaus allegedly described himself as “chosen” by “Saint [Brenton] Tarrant,” the gunman who killed 51 people at mosques in New Zealand earlier this year.

“My time is up, I was chosen by Saint Tarrant after all … We can’t let this continue, you gotta bump the race war threat in real life … it’s been fun,” one post obtained by The Guardian reads.

Manshaus also allegedly praised Tarrant and two other suspected shooters in a meme.

Tarrant is described as having “addressed the Muslim problem." Patrick Crusius, who has been charged with last week's shooting in El Paso, Texas, which left 22 dead, is praised for “fighting to reclaim his country," according to The Guardian.

The meme also praised the attacker suspected of killing a woman at the Chabad of Poway synagogue in California in April.

The posts were both reportedly made on a new messaging board called Endchan, which describes itself as “an anonymous image-board that promotes ideas over identity,” as well as an older board called 4chan.

Crusius allegedly posted an anti-Hispanic manifesto on 8chan, an online board which has since been dropped by multiple web services.
