On 11 May 1992, ARBiH attacked JNA barracks in Krupa and transported the captured JNA reservists into a newly formed concentration camp "Silos" in Tarčin. Additional 11 JNA reservists were brought in from the barracks in Zovik and Hadžići. The camp was later used to imprison Serb civilians, mostly elderly from neighbouring communities.[better source needed] Until 27 January 1996, when the camp was finally closed down, reported 23 prisoners were killed within the walls of the camp. In 2011, eight former ARBiH soldiers were arrested for the crimes at "Silos" and the trial began in July 2013.
