The killings were perpetrated by units of the Bosnian Serb Army of Republika Srpska (VRS) under the command of Ratko Mladić. The Scorpions, a paramilitary unit from Serbia, who had been part of the Serbian Interior Ministry until 1991, also participated in the massacre. Prior to the massacre, United Nations (UN) had declared the besieged enclave of Srebrenica, in eastern Bosnia, a "safe area" under UN protection. However, the UN failed both to demilitarize the Army of the Republic of Bosnia and Herzegovina (ARBiH) within Srebrenica and to force withdrawal of the VRS surrounding Srebrenica. UNPROFOR's 370 lightly armed Dutchbat soldiers were unable to prevent the town’s capture and the subsequent massacre. A list of missing or killed people during the massacre compiled by the Bosnian Federal Commission of Missing Persons contains 8,373 names. , 6,838 genocide victims have been identified through DNA analysis of body parts recovered from mass graves; , 6,066 victims have been buried at the Memorial Centre of Potočari.
