What happened to the Nazi concentration camps in Poland after WW II?
Some former Nazi concentration camps in Poland, most notably Auschwitz Birkenau, and Majdanek, continued to be operated by Soviet NKVD, SMERSH, and Polish secret police units to house, torture, and murder Polish resistance fighters, Russian prisoners of war, and in many instances, also innocent German civilians. See Central Labour Camp in Potulice, and Jaworzno Central Labour Camp for more information.
