Chaos during the Polish take-over of the city culminated in a two-day-long riot , in which mostly Polish criminals and soldiers started pillaging the city ; over the course of the riots , approximately 340 civilians , 2/3 of them Ukrainians and the rest Jews , were murdered . The Jews were accused of cooperating with Ukrainians , and it was claimed that approximately 150 Jews were murdered and 500 Jewish shops and businesses were ransacked in reprisal , although the Morgenthau commission reported only 64 Jewish deaths . The Jewish deaths were overstated in some initial reports in the western press and the incident has come to be known as the " Lwów pogrom " . After establishing order within the city , Polish authorities punished a number of people accused of participation in riots
