Slovenian Commission on Concealed Mass Graves is responsible for leading investigations into places where there may be bodies from the period of and after the Second World War. It currently has a list of around 570 potential mass grave sites, based on evidence on the ground and reports from local people. Not all of these refer to killings (alleged or proven) in 1945.
