Full-scale war, marked by appalling brutality inflicted on the civilian population and extreme violations of international humanitarian law, has been raging in Bosnia-Hercegovina since early April 1992. Mistreatment in detention, the taking of hostages and the pillaging of civilian property is widespread. The most basic safeguards intended to protect civilians and medical facilities have been flagrantly ignored. The indiscriminate use of force by Serbian troops has caused excessive collateral damage and loss of civilian life. A policy of "ethnic cleansing" has resulted in the summary execution, disappearance, arbitrary detention, deportation and forcible displacement of hundreds of thousands of people on the basis of their religion of nationality. In sum, the extent of the violence and the fact that it is targeted along ethnic/religious lines raises the question of whether genocide is taking place. Helsinki Watch calls on the Security Council of the United Nations to exercise its authority under the 1951 Convention on the Prevention and Punishment of the Crime of Genocide to intervene in Bosnia-Hercegovina to prevent and suppress genocide. Helsinki Watch also calls upon the UN Security Council to enforce the prohibition of "grave breaches" of the Geneva Convention by establishing an international tribunal at the highest level to investigate, prosecute, adjudicate and punish those on all sides who have been responsible for war crimes in the territory of the former Yugoslavia.
