UPA killed 100 Poles in Belz

At the beginning of World War I, Belz had 6100 inhabitants, including 3600 Jews, 1600 Ukrainians, and 900 Poles.

During the German and Soviet invasion of Poland (September 1939), most of the Jews of Belz fled to the Soviet Union in Autumn 1939 (the German–Soviet Treaty of Friendship, Cooperation and Demarcation).

However, by May 1942, there were over 1,540 local Jewish residents and refugees in Belz.

On June 2, 1942, 1,000 Jews were deported to Hrubieszów and from there to the Sobibór extermination camp. Another 504 were brought to Hrubieszów in September of that year, after they were no longer needed to work on the farms in the area
