Thousands Mourn on 15th Anniversary of Srebrenica Massacre VOA News 11 July 2010 A pile of more than 16,000 shoes, each pair representing a victim of the 1995 Srebrenica massacre are placed with a UN sign in front of the Brandenburg Gate in Berlin, Sunday July 11, 2010 Photo: AP A pile of more than 16,000 shoes, each pair representing a victim of the 1995 Srebrenica massacre are placed with a UN sign in front of the Brandenburg Gate in Berlin, Sunday July 11, 2010. The shoes were collected to make 'The Pillar of Shame', German activist's Phillip Ruch's monument to Srebrenica. On July 11, 1995, more than 8,000 Bosnian Muslim men and youths were slaughtered by Bosnian Serb troops in an enclave supposedly protected by U.N. peacekeepers. Tens of thousands of mourners gathered Sunday in the eastern Bosnian town of Srebrenica to re-bury hundreds of massacre victims on the 15th anniversary of the worst mass killing in Europe since World War II. Relatives gathered in bright sunshine on the edges of a field filled with 775 shrouded coffins, as senior clerics intoned Muslim prayers for the dead. Freshly dug graves waited nearby. Srebrenica had been declared a safe zone by the United Nations as the Bosnian war raged in the early 1990s, and thousands of Bosnian Muslims sought protection from Bosnian Serb forces. However, the U.N. resolution creating the safe zones was unclear about protection provisions, and in July 1995 Bosnian Serb forces overran a token Dutch force and captured the enclave. Experts say up to 8,000 Muslim men and boys were executed by Serb forces at several locations near Srebrenica in July 1995.  Former U.N. Secretary-General Kofi Annan later called the massacre the darkest day in United Nations' history. The bodies buried Sunday are the result of a slow forensic process of identification begun in the aftermath of the 1991-1995 war, as bodies were exhumed from mass graves in the area. Some 3,000 victims have so far been identified and re-buried. The International Court of Justice has officially ruled that Bosnian Serb troops, led by General Ratko Mladic, committed genocide at Srebrenica. Mladic remains a fugitive from justice and is believed to be in hiding somewhere on the Bosnian-Serbian frontier. .
