Over the next week, the full scale of Aum's activities was revealed for the first time. At the cult's headquarters in Kamikuishiki on the foot of Mount Fuji, police found explosives, chemical weapons, and a Russian Mil Mi-17 military helicopter. While the finding of biological warfare agents such as anthrax and Ebola cultures was reported, those claims now appear to have been widely exaggerated. There were stockpiles of chemicals that could be used for producing enough sarin to kill four million people.
