According to legal experts, as of early 2008, 45 Serbs, 12 Croats and 4 Bosniaks were convicted of war crimes by the ICTY in connection with the Balkan wars of the 1990s. Both Serbs and Croats were indicted and convicted of systematic war crimes (joint criminal enterprise), while Bosniaks were indicted and convicted of individual ones. Most of the Bosnian Serb wartime leadership – Biljana Plavšić, Momčilo Krajišnik, Radoslav Brđanin, and Duško Tadić – were indicted and judged guilty for war crimes and ethnic cleansing.
