THE HAGUE: A top Bosnian Serb army official, General Djordje Djukic, was indicted by an international war crimes tribunal. Djukic is accused of crimes against humanity for staging repeated attacks on civilian sections of Sarajevo between 1992 and 1995. The charges may still change pending the results of an ongoing investigation. The indictment was issued after Djukic refused to cooperate with Chief Prosecutor Richard Goldstone's investigation of other alleged Serb war crimes. Serbs have protested Djukic's arrest, charging that the war crimes tribunal has unfairly targeted Serbs in their investigation. Since the tribunal was established by the UN in 1993, 46 Serbs and only seven Bosnian Croats have been indicted. But TIME's Marquerite Michaels says the focus will soon shift to the Croats. "The tribunal will soon begin investigating "Operation Storm", the Croatian offensive against Serbs in the Krajina last August," says Michaels, "and many indictments will probably stem from that. But the tribunal has to take into account the reactions of Franjo Tudjman and Slobodan Milosevic. The two men are key to the upholding of the Dayton Agreement and cannot be pressured too much."
