Gas van

The gas van was an "extermination" method devised by Nazi Germany to murder their victims during World War II.

It was a vehicle with an air-tight compartment for victims into which exhaust fumes were transmitted while the engine was running. As a result the victims were gassed with carbon monoxide, resulting in death by carbon monoxide poisoning.

Gas vans were used until more "effective" extermination methods were put into use.
