Awful atrocities were carried out at the Janowska concentration camp and surrounding Lvov(aka Lwow and Lviv) by the Nazis, Soviet troops and Ukrainian nationalists. To an extend it reminds me of the current situation in Aleppo where the population is being subjected by violence from all sides.
In September 1941, the Germans set up a factory on Janowska Street in the northwestern suburbs of Lvov, in southeastern Poland(today Lviv in Ukraine). This factory became part of a network of factories, the German Armament Works, owned and operated by the SS. Jews were used as forced laborers, mainly in carpentry and metalwork. In October 1941, the Germans established a camp housing the forced laborers next to the factory.
After the Nazi-Soviet invasion of Poland at the beginning of World War II, the city of Lwów in the Second Polish Republic(now Lviv, Ukraine) was occupied in September 1939 by the Soviet Union under the terms of the Ribbentrop-Molotov Pact.
