A number of human rights groups have claimed that the OPG committed war crimes against civilians . Radosavljević was the person in charge of the military operation in Račak on 15 January 1999 , which would become known as the Račak massacre . The Serbian War Crime 's prosecutor also brought him in connection with the killing of the Bytyqi brothers , three Albanian American brothers who came to Kosovo to fight on the side of the KLA . Radosavljević was in charge of a Serb police training facility at Petrovo Selo where the Bytyqi brothers were detained , tortured , executed , and buried in a mass grave . In December 2018 , US State Department issued sanctions on Radosavljević after credibly implicating him in the 1999 murder of the Bytyqi brothers
