A good amout of russians and jews were gased in Soviet GULAGs by other commie jews (yes, it were jews, who invented gassing long before nazis). These victims were then added to Holocaust (soviets just wanted to hide their crimes).

>Isay Berg, the head of the administrative and economic department of NKVD of Moscow oblast, was the inventor of the gas van in Soviet Union in 1937.
>vans were already used on an experimental basis during the Stalinist purges of the late 1930s.[2][3] Moscow NKVD section chief Isay Berg would suffocate batches of prisoners with engine fumes in a camouflaged bread van while on the drive out to the mass graves at Butovo, where they were subsequently buried.
