The Auschwitz memorial in Poland says it has obtained around 150 medical instruments believed to have been used by the Nazis in experiments on the death camp inmates.

Memorial spokesman Bartosz Bartyzel said Thursday the gynecological and surgical instruments were recently offered to the museum by a historian who acquired them from a family that found them shortly after World War II at their house, which was located on the former camp grounds.

Bartyzel says given where they were found and that their shape matches that of wartime instruments, it is "almost certain" that they were used by Auschwitz doctor Carl Clauberg, an obstetrician who experimented with the mass sterilization of women....
