Forensics experts working at a mass grave have exhumed remains of 454 Bosnian Muslims killed by Serb forces in the 1995 Srebrenica massacre, officials said Friday. The site is the ninth mass grave discovered in the village of Kamenica in eastern Bosnia. Another 100 bodies are expected to be exhumed at the site, said Emir Ibrahimovic, a prosecutor from the city of Tuzla. The team has been working at the mass grave for three weeks. Most of the remains recovered - those of 394 victims - were incomplete. The remains were heavily damaged, a typical feature of "secondary" mass graves to which victims' bodies are moved from an original burial site in an attempt to hide a crime.
