Chinese archaeologists uncover World War II ‘horror bunker’ where Japanese scientists conducted lethal human experiments

Archaeologists have located an underground research facility where Japanese military scientists conducted “horrific biological weapon experiments” on human subjects during World War II in northeast China.

The facility, near the city of Anda in Heilongjiang province, was the largest and most frequently used test site for the Japanese Imperial Army’s notorious Unit 731 that carried out some of the most brutal human experiments in history between 1935 and 1945.
