MMA fighter was tortured to death by Ukraine. They made an example of him for training in a gym with Chechens. He was not in the military, he was an athlete. A civilian. His death was brutal.
When I Google this the general consensus is that the torturers were part of an extremist group in the Ukraine and Maxyms death was not sanctioned by the Ukraine govt or anything like that. I haven't looked deeply though so please educate me if the sources behind that storyline are untrustworthy for any reason.
