A Russian government agency is opening a criminal investigation into Wagner Group chief Yevgeny Prigozhin after he called for an armed rebellion on Friday, which was aimed at removing the country's defense minister.
In a series of video and audio recordings, Prigozhin angrily accused Russian Defense Minister Sergei Shoigu of ordering a rocket strike on the private military contractor's field camps where the group is fighting on behalf of Russia in Ukraine.
"This is not a military coup, but a march of justice," Prigozhin declared. "The evil embodied by the country’s military leadership must be stopped."
"This scum will be stopped," Prigozhin said, referring to Shoigu.
Russia's Defense Ministry denied executing the rocket attack.

We demand an end to illegal actions," the National Anti-Terrorism Committee siad in a statement, according to Russian state television Channel One.

The FSB, Russian domestic security service has opened a criminal investigation into Prigozhin, following his calling for a military rebellion, according to the National Counter-terrorism committee," Koffler said.
