TOKYO - The Imperial Japanese Army conducted experiments on its own soldiers during the Second Sino-Japanese War, exposing troops hospitalized for mental illnesses and deemed unfit for combat to malaria-carrying mosquitoes, a researcher at Meiji Gakuin University said Monday.

Military doctors studying the transmission of malaria exposed 10 soldiers hospitalized in Japan, who had conditions including schizophrenia, to mosquitoes that had fed on the blood of infected troops.
