Members of other ethnicities were also killed, such as Serbs deemed disloyal by the local authorities. The killing was committed by a local paramilitary group known as Mirko's Chetniks and by the Serb Volunteer Guard (SDG, also known as Arkan's Tigers), a Serbia-based paramilitary group led by Željko Ražnatović (aka Arkan). The SDG were under the command of the Yugoslav People's Army (JNA), which was controlled by Serbian President Slobodan Milošević.
