Bosnia-Herzegovina ? Forensic experts said Friday they found a new mass grave in northeastern Bosnia believed to contain the remains of more than 100 victims of the 1995 Srebrenica massacre where Serb forces buried some of the almost 8,000 victims.

The grave in Snagovo village, about 30 miles north of Srebrenica, was found after experts received a tip from an undisclosed source, said Murat Hurtic, head of Bosnia’s Missing Persons Commission.

It is the seventh mass grave Hurtic’s team has found near Srebrenica, the scene of Europe’s worst massacre since World War II.

Local and international experts have been digging for years in Snagovo, finding so-called “secondary” mass graves in the area just outside of the city of Zvornik on the border with Serbia.

Such graves contain bodies originally buried elsewhere, but later moved to the “secondary” location in an effort to cover up the crime. The remains are often only partial, as those involved in reburying them often used bulldozers to bring them up from the first grave.
