Victims of international crimes, such as genocide, crimes against humanity and war crimes, are considered crucial in establishing the evidence in cases before international criminal tribunals. Yet, due to the geographic, political, ethnic or religious circumstances in the country of origin, the nature of the crimes concerned and the nature of the victims' or accuseds' involvement in the crimes, international cases also bring with them significant risks for victims/witnesses and challenges for tribunals in protecting them. At times, individuals have disclosed identifying information of victims/witnesses in violation of protection orders of the tribunal, which has led to threats, intimidations and even murders, and ultimately, in a number of cases, the unwillingness of victims/witnesses to testify. Although the tribunals have measures at their disposal to sanction individuals breaching protection orders, the question remains how big the problem of witness interference really is and how to address this issue adequately.
