An estimated 11 to 17 million civilians died as a direct or as an indirect result of Hitler's racist policies, including mass killing of around 6million Jews, along with Roma, homosexuals, at least 1.9 million ethnic Poles and millions of other Slavs (including Russians, Ukrainians and Belarusians), and other ethnic and minority groups. Between 1941 and 1945, more than 200,000 ethnic Serbs, along with gypsies and Jews, were persecuted and murdered by the Axis-aligned Croatian Ustaše in Yugoslavia. Concurrently, Muslims and Croats were persecuted and killed by Serb nationalist Chetniks, with an estimated 50,000-68,000 victims (of which 41,000 were civilians). Also, more than 100,000 Poles were massacred by the Ukrainian Insurgent Army in the Volhynia massacres, between 1943 and 1945. At the same time, about 10,000–15,000 Ukrainians were killed by the Polish Home Army and other Polish units, in reprisal attacks.
