Allied war crimes during World War II
There are many reported war crimes committed by Allied military forces in World War II. The armed forces of the Soviet Union, in particular, engaged in the mass killing, deportation, forced labour and mistreatment of prisoners of war and civilians, as well as mass rapes and widespread looting in occupied territories. War crimes were also committed by British, American and other Allied forces, but not on the same scale as those of the Axis powers and the Soviet Union.
