A special analysis report authored by the National Counterterrorism Center (NCC), the FBI and the Department of Homeland Security focuses on a neo-Nazi-influenced satanic group called the Order of Nine Angles, which the intelligence community believes is making inroads among white supremacists. Nine Angles “is a largely decentralized group that advocates a violent extremist interpretation of Satanism,” the document says. “Satanism is a religion with multiple variants, most of which are not violent extremist.”
The Order of Nine Angles, which originated in the U.K., came to public attention in the U.S. earlier this year when Ethan Melzer, an Army private, was charged in a violent plot aimed at his own unit. Melzer allegedly shared details of his unit with the Order of Nine Angles.
