6 June 1945
The Barbara Pit massacre (Slovene: Pokol v Barbara rovu, Croatian: Pokolj u Barbarinom rovu), also known as the Huda Jama massacre, was the mass killing of prisoners of war of Ante Pavelić's NDH Armed Forces and the Slovene Home Guard, as well as civilians, after the end of World War II in Yugoslavia in an abandoned coal mine near Huda Jama, Slovenia. More than a thousand prisoners of war and some civilians were executed by the Yugoslav Partisans during May and June 1945, following the Bleiburg repatriations by the British.
