A Bosnian government inter-ethnic panel has established that more than 19,000 Bosnian Serb military, police and civilian personnel were operating in the Srebrenica region at the time of the massacre there ten years ago.
A Muslim member of the panel told a news conference that 17,000 of them had been identified by name.
The list is part of an investigation aimed at identifying those responsible for the massacre in July 1995 in which around 8,000 Muslim men and boys were taken away and executed by Bosnian Serb forces.
The report will be passed to state prosecutors and the War Crimes Tribunal in The Hague.
Meanwhile, the Bosnian Serb parliament has voted in favour of unifying its ethnically divided police force, removing an obstacle in the way of Bosnia's eventual membership of the European Union.
The vote on the legislation was carried out just hours before an EU deadline.
The European Commission said the police reform proposal was a crucial step towards enabling it to recommend the start of negotiations on a Stabilisation and Association Agreement.
