Amsterdam - The bodies of more than 165 victims of ethnic cleansing have been unearthed at three mass grave sites in the Prijedor region of north-west Bosnia this year, the United Nations' war crimes tribunal said yesterday. "The human remains recovered from these three sites were victims of the ethnic cleansing which occurred in north-west Bosnia and Herzegovina during 1992," the tribunal's chief prosecutor, Mr Carla Del Ponte, said in a statement. The discoveries bring the total number of bodies found during four years of exhumations in Bosnia to about 2,077.
