Former members of Unit 731, a Japanese military unit that conducted illegal human experiments during World War II, can be seen discussing the atrocities they committed in a video that was recently released. Coming just before the 69th anniversary of Japan's surrender on Aug. 15, the video has shed new light on the unit's past activities in northeast China's city of Harbin. They are telling history to a Chinese man who has been researching the unit for 16 years.
