During the Bosnian War, Bosnian Serb forces conducted a sexual abuse strategy against thousands of Bosnian Muslim girls and women which became known as a "mass rape phenomenon". No exact figures on how many women and children were systematically raped by the Serb forces in various camps were established, but estimates range from 20,000 to 50,000. Mass rape mostly occurred in eastern Bosnia (especially during the Foča and Višegrad massacres), and in Grbavica during the Siege of Sarajevo. Numerous Bosnian Serb officers, soldiers and other participants were indicted or convicted of rape as a war crime by the ICTY and the Court of Bosnia and Herzegovina. The events inspired the Golden Bear winner at the 56th Berlin International Film Festival in 2006, called "Grbavica".
