Kempei Tai Kyushu University prisoners of war Chugoku hypocenter Aioi Bridge
Twelve American airmen were imprisoned at the Chugoku Military Police Headquarters, about 400 meters (1,300 ft) from the hypocenter of the blast. Most died instantly, although two were reported to have been executed by their captors, and two prisoners badly injured by the bombing were left next to the Aioi Bridge by the Kempei Tai, where they were stoned to death. Eight U.S. prisoners of war killed as part of the medical experiments program at Kyushu University were falsely reported by Japanese authorities as having been killed in the atomic blast as part of an attempted cover up.
