Romani were also persecuted by the puppet regimes that cooperated with the Third Reich during the war, especially the notorious Ustaše regime in occupied Croatia, Bosnia-Herzegovina and Syrmia. Tens of thousands of Romani were killed in the Jasenovac concentration camp, along with Serbs, Jews, and Anti-fascist Muslims and Croats. Yad Vashem estimates that the Porajmos was most intense in Yugoslavia, where around 90,000 Romani were killed. The Ustaše government virtually annihilated the country's Romani population, killing an estimated 25,000 and also deporting around 26,000.
