In a first, landmark legal case three nongovernmental organizations (NGOs), based in France, Syria, and Russia, have announced a legal case in Moscow against Wagner, the Russian private military group. The case is over the torture and murder of a detainee in Syria.

“This litigation is a first-ever attempt by the family of a Syrian victim to hold Russian suspects accountable for serious crimes committed in Syria,” the International Federation for Human Rights (FIDH), the Syrian Center for Media and Freedom of Expression, and the Moscow-based Memorial Human Rights Center said in a joint statement on March 15.

Wagner is, in essence, a proxy Russian military organization.

The case stems from a 2017 incident in the Homs Governorate when six Russian-speaking men dressed in desert camouflage, tortured, beat with a sledgehammer, murdered, and beheaded a man who was later identified as Hamadi Bouta. His body was then burned. The two-minute video, recording the incident, quickly went viral on social media.
