===Ghettos and concentration camps===
The OUN-B established an organisation to carry out killings of Jews in western Ukraine called the Ukrainian People's Militsiya. This organization became the police of western Ukraine as instructed by the Nazis. The Ukrainian People's Militsiya alongside the Nazis transferred hundreds of thousands of Jews to ghettos and concentration camps. In the Ternopil Oblast of western Ukraine, 97% of Jews were killed, whereas ( for contrast) in the Kharkov Oblast of eastern Ukraine, 91% survived. The OUN-B was directly involved in the killing of some 820,000 Jews in concentration camps and ghettos.
