Gas vans are vehicles or alleged vehicles equipped with homicidal gas chambers. They kill or allegedly kill by using exhaust gas from the vehicle engine in order to cause carbon monoxide poisoning.
Such vehicles using gasoline engines were used in the Soviet Union to kill dissidents in limited numbers.
Gas vans using diesel engines were allegedly used during the Holocaust by the Einsatzgruppen behind the Eastern Front. They were allegedly also used in some Holocaust camps such as Chelmno (the alleged main killing method there) and Sajmište. Carbon monoxide (but not gas vans) was allegedly also used in homicidal gas chamber in several other camps.
