Analysis of information sources in references of the Wikipedia article "Genocide of Serbs in the Independent State of Croatia" in English language version.
..the Ustasha embarked on a policy of genocide which, in conjunction with the Nazi Holocaust with which it overlapped, claimed the lives of at least 30,000 Jews, a similar number of Gypsies and perhaps nearly 300,000 Serbs.
The Independent State of Croatia willingly cooperated with the Nazi "Final Solution" against Jews and Gypsies, but went beyond it, launching a campaign of genocide against Serbs in "greater Croatia." The Ustasha, like the Nazis whom they emulated, established concentration camps and death camps.
