Acting under Chapter VII of the United Nations Charter, the Council went on to demand that all parties and others concerned treat Srebrenica and its surroundings as a safe area which should be free from any armed attack or any other hostile act, further demanding the cessation of all hostilities and withdrawal by Bosnian Serb paramilitary forces from areas around Srebrenica.
[1] It also demanded that Federal Republic of Yugoslavia (Serbia and Montenegro) cease supplying weapons, military equipment and other services to Bosnian Serb paramilitary units in Bosnia and Herzegovina.
The council condemned the "abhorrent campaign of ethnic cleansing" by the Bosnian Serb paramilitaries and its actions of forcing the evacuation of the civilian population from Srebrenica.
Finally, Resolution 819 demanded that all parties ensure the safety of the protection force, United Nations personnel and other international organisations, allowing for the safe transfer of injured civilians from Srebrenica and its surrounding areas, and announced its decision to send a mission of members of the security council to assess the situation in Bosnia and Herzegovina.
[3] Despite its preemptive wording, Resolution 819 failed to prevent the Srebrenica massacre in July 1995, when the United Nations Protection Force were taken prisoner and the refugees from the fallen enclave fell into the hands of the forces of Bosnian Serb General Ratko Mladić, subsequently indicted by the International Criminal Tribunal for the Former Yugoslavia for war crimes including genocide.
