Several thousand people have attended a funeral service in northwestern Bosnia for 86 Muslims who were killed by Serbs in one of the worst atrocities of the country’s 1992-95 war.

Relatives of the victims, religious leaders and others gathered on Saturday at a football stadium near the town of Prijedor, standing solemnly behind lines of coffins draped with green cloths in Muslim tradition.

The victims were aged between 19 and 61. They were among some 200 Bosnian Muslims and Croats from Prijedor who were executed in August 1992 on a cliff on Mt Vlasic known as Koricanske Stijene.

The United Nations war crimes tribunal for the former Yugoslavia has sentenced several ex-Bosnian Serb policemen for the slaughter.
