I've posted it before, I'll post it again: A great article by @PKonst2d about the role played by far-right Greek volunteers/militia in the #Srebrenica massacre/genocide. It's a topic that, as you might suspect, has received zero coverage in Greek media https://medium.com/athenslivegr/the-greek-link-to-srebrenica-bf5f844e892
For more on this topic, check out the investigative blog of @basilikimetat who spent years uncovering their role. Scroll down for short video on showing some of the militiamen https://xyzcontagion.wordpress.com/2015/06/18/x-pressed-bournazos-srebrenica-translation-of-avgi/
Greeks supported the Serbs uncritically in the Yugoslav war. I remember TV shows going on and on about the Serbians and here's a 2002 Dutch documentary on this very topic (brought to my attention by @basilikimetat)
