TOKYO (AP) — A pile of human bones discovered in a Tokyo repository has sparked debate over their origins. Some believe they are remnants from early 20th-century anatomy classes, while others suspect they may be the unburied victims of wartime atrocities.
The bones, including skulls with cuts and parts of skeletons, were unearthed in 1989 at the site of the wartime Army Medical School, known for its ties to a germ and biological warfare unit. Unit 731, based in northeast China during the war, conducted gruesome experiments on prisoners of war, injecting them with diseases and performing surgeries without anesthesia.
