A British offshoot of an American neo-Nazi group is calling for Prince Harry’s assassination — branding him a “race traitor” because of his marriage to Meghan Markle.

An investigation by the BBC that looked at hundreds of vile messages and images posted over months on an online gaming server found that the Hitler-loving group Atomwaffen Division has expanded to the UK under the name Sonnenkrieg Division.

One image posted to the server shows a gun being pointed at Prince Harry, with the words “See ya later, race traitor!” suggesting he should be shot for marrying Markle, who is of mixed race.

Another image shows a woman hanging from a noose and states that white women who date non-white men should be killed.

The chat logs include messages from leaders of Atomwaffen Division — the first word is German for “atomic weapon” — corresponding about the creation of the Sonnenkrieg Division.

Members of Atomwaffen Division, a hate group founded in the US in 2015 with the aim of overthrowing civilization to build a national socialist state, are believed responsible for at least five deaths in Florida, Virginia and California.

The UK outpost was set up by a 21-year-old university student named Andrew Dymock, the BBC found in their report published Wednesday. Dymock denies any involvement.

One person on the server named “Blitzy” — who the BBC reported is Dymock — discussed plans to go to the US to meet Atomwaffen members in person and stated “kill all police officers,” saying they should be “raped to death.”

It’s believed there are 10 to 15 members of the group in the UK and some European countries. The Anti-Defamation League believes there may be about 80 members in the US.

The group is obsessed with Charles Manson’s attempts to spark a race war and routinely holds wilderness excursions and military-style training events called “hate camp,” where they’re believed to engage in firearms training.

One member of the vile group, Samuel Woodward, this year allegedly stabbed California college student Blaze Bernstein 20 times for being Jewish and gay.
