A fictitious group invented to support the fake narrative that the Uke Azov woman wasn’t behind it. They didn’t mean to murder that young woman, it didn’t play well, and they needed a damage control story.
Fake news.
It is a newly created and fake group, but I’m leaning toward either the CIA folks or Chinese folks having created it. If you read through the manifesto, there are elements of nationalism and socialism laid out....which leads to an odd conclusion resembling to a 1930s German political party.
