The Zvornik massacre refers to acts of mass murder and violence committed against Bosniaks and other non-Serb civilians in Zvornik by Serb paramilitary groups ("Arkanovci", Territorial Defence units, White Eagles, Yellow Wasps) at the beginning of the Bosnian War in 1992. Estimates show that 40,000 Bosniaks were expelled from the Zvornik district. It was the second city in Bosnia and Herzegovina that was forcefully taken over by Serb forces during the Bosnian War.
