UN's International Criminal Tribunal for the Former Yugoslavia

A report published on Wednesday by the Independent International Commission of Inquiry on the Sufferings of All Peoples in the Srebrenica Region between 1992 and 1995, which was set up by the government of Bosnia's Serb-dominated Republika Srpska, seeks to cast doubt on whether thousands of Bosniaks who were murdered by Bosnian Serb forces in July 1995 were innocent civilians.

Trendafilova urged European nations to consider "comprehensive cooperation agreements" so witnesses and their families can be relocated to Western Europe.

"Without these agreements, it will be very difficult if not impossible in some cases to ensure that testimony can be given freely and without any fear," she said.
