Postscript to Sarajevo's Anguish: Muslim Killings of Serbs Detailed
Musan Topalovic and other Muslim paramilitary leaders rose from shadows to become warlords and folk heroes in first days of Bosnian war; it has become increasingly clear that they also played far darker role in war, murdering scores of Bosnian Serb civilians who remained in Sarajevo when fighting broke out in 1992; accounts of killings, described by witnesses and previously secret court documents, are first public indication that Muslim soldiers were involved in significant wartime atrocities against ethnic Serbian civilians; savagery does not appear to have been comparable in scale to Bosnian Serbs' organized campaign of 'ethnic cleansing'; map; photo of Kazani pit, site where Bosnian Muslims killed Serbian civilians and dumped their bodies (M)
