Authorities in Serbia have detained several former members of a Serbian paramilitary unit who appeared in a videotape showing executions after the Serb capture of the Bosnian Muslim town of Srebrenica.

Prosecutors at the war crimes trial of former Yugoslav President Slobodan Milosevic showed the videotape Wednesday during testimony before the United Nations war crimes tribunal in The Hague. About 8,000 Muslim men and boys were killed after the 1995 fall of Srebrenica, in eastern Bosnia-Herzegovina.
