Right, because there were never any Ukraine Nazis serving Hitler in Ukraine? Right?
Here's the answer to your question:
"The antisemitic canard of Jewish Bolshevism provided justification for the revenge killings by the ultranationalist Ukrainian People's Militia, which accompanied German Einsatzgruppen moving east.[26] In Boryslav (prewar Borysław, Poland, population 41,500), the SS commander gave an enraged crowd, which had seen bodies of men murdered by NKVD and laid out in the town square, 24 hours to act as they wished against Polish Jews, who were forced to clean the dead bodies and to dance and then were killed by beating with axes, pipes etc. The same type of mass murders took place in Brzezany. During Lviv pogroms, 7,000 Jews were murdered by Ukrainian nationalists, led by the Ukrainian People's Militia.[26][27][28] As late as 1945, Ukrainian militants were still rounding up and murdering Jews.[29]"
