BELGRADE, October 21 (IslamOnline & News Agencies) - Chief UN war crimes prosecutor Carla Del Ponte said Monday, October 21, she delivered several indictments to Belgrade linked to the 1995 massacre of more than 7,000 Muslims in Srebrenica during the war in Bosnia, the worst atrocity in Europe since World War II.

The indictments were delivered under seal and Del Ponte declined to give out the names of those charged. However, the UN war crimes tribunal, later in the day, unveiled the indictments as genocide charges against three Bosnian Serb officers.

The indictments charge Drago Nikolic, a lieutenant in the Bosnian Serb Zvornik Brigade, Vujadin Popovic, a lieutenant colonel in the Drina Corps, and Ljubisa Beara, who served in the Bosnian Serb army as chief security officer, with genocide, crimes against humanity and war crimes, reported Agence France-Presse (AFP).

The attack on the UN-protected enclave of Srebrenica was led by the Drina Corps and its Zvornik and Bratunac Brigades.

According to the indictment, the three were part of a scheme "to forcibly transfer women and children from the Srebrenica enclave to Kladanj... and to capture, detain, summarily execute by firing squad, bury, and rebury thousands of Bosnian Muslim men and boys aged 16 to 60 from the Srebrenica enclave".

More than 7,000 Bosnian Muslim men and boys were killed when the town of Srebrenica, officially placed under the protection of UN peacekeepers from The Netherlands, fell to Bosnian Serb forces in July 1995.

Del Ponte said she delivered the sealed indictments, without providing further details, after meeting Yugoslav Foreign Minister Goran Svilanovic.

She lashed out at Belgrade's poor cooperation record with the International Criminal Tribunal for the former Yugoslavia (ICTY), on the extradition of war crimes suspects believed to be in hiding on Yugoslav soil.

Del Ponte said court chairman Claude Jorda would present a formal complaint against Yugoslavia to the UN Security Council next week.

Since April, when the Yugoslav parliament adopted a law on cooperation with the tribunal, five men surrendered to the ICTY voluntarily while one suspect was arrested and handed over.

According to Svilanovic, there were 13 more men wanted by the tribunal and believed to be in hiding in Yugoslavia.

Del Ponte has repeatedly called on Belgrade to step up a hunt for a key suspect, the Bosnian Serb wartime military commander Ratko Mladic, whom she insists is hiding in Serbia.

Asked if there had been any progress on Mladic's arrest, Del Ponte said: "No, nothing... I am afraid that I don't know where Mladic is at this time".

"But there was information since July on the whereabouts of Mladic and I gave all this information to the Serbian interior minister, and I received no feedback, unfortunately," she added.

Mladic and his former boss, wartime Bosnian Serb president Radovan Karadzic, top the list of most-wanted suspects at the UN tribunal.

About a dozen people, including Mladic, Karadzic and Milosevic, have been indicted for war crimes, crimes against humanity and genocide for their roles in the Srebrenica massacre, the siege of Sarajevo and other atrocities.

Bosnian forensic experts said Friday, October 18, that they removed a large quantity of human remains from a newly-discovered fifth mass grave believed to hold victims of the 1995 Srebrenica massacre.
