How many deaths there in ww2 because of gas attacks?

During World War II, the use of gas attacks was largely limited compared to World War I, primarily due to the widespread recognition of its horrors and the development of protective measures. While chemical weapons were employed, particularly by the Axis powers, the number of deaths specifically attributed to gas attacks in WWII is estimated to be in the low thousands. Notably, the Holocaust involved the use of gas in extermination camps, which contributed significantly to the overall death toll. However, exact figures are difficult to determine due to the chaotic nature of war and the lack of comprehensive records.
