Dozens of mass graves containing hundreds of corpses have been uncovered since the beginning of the First Chechen War in 1994. As of June 2008, there were 57 registered locations of mass graves in Chechnya. According to Amnesty International, thousands may be buried in unmarked graves including up to 5,000 civilians who disappeared since the beginning of the Second Chechen War in 1999. In 2008, the largest mass grave found to date was uncovered in Grozny, containing some 800 bodies from the First Chechen War in 1995. Russia's general policy to the Chechen mass graves is to not exhume them.
