HAJVAZI, Bosnia-Herzegovina—Forensic experts have found 10 bodies as they began to excavate a mass grave where Muslim Bosniaks killed during the 1995 massacre in the eastern town of Srebrenica are believed to have been hidden.

Srebrenica was the worst massacre in Europe since World War II and took place in an area that was officially under U.N. protection during the 1992-95 Bosnian war.

The execution of over 8,000 men and boys has been defined as genocide, and Serb Gen. Ratko Mladic, who commanded Serb troops who conducted the massacre, is now on trial before a U.N. tribunal.

In addition to the 10 bodies recovered Wednesday, the team expects to find at least 10 more in the grave.

Such searches continue to attract Bosniaks whose relatives disappeared during the war.
