Belzec

The first of three killing centers established under Operation “Reinhard,” the plan to murder all Jews in the Generalgouvernement. Located in the Lublin District of the Generalgouvernement, Belzec killing center operated from March 1942 until December 1942. During that time, an estimated 434,500 Jews and an unknown number of other prisoners were murdered in Belzec in gas chambers using carbon monoxide gas from diesel engines, a method developed for the Aktion T4 "euthanasia" program.
