The Aum Shinrikyo Cult & the Tokyo Gas Attack

On the morning of March 20, 1995, millions of rush hours commuters boarded trains across Tokyo, just as they countless other mornings. Unbeknownst those millions of riders, five of those trains were carrying large quantities of a nerve agent called Sarin, a colorless, odorless liquid that, when released into the air, can cause extreme respiratory problems and eventually death. As the trains traveled to their respective destinations through the underground system, the bags of Sarin became punctured and released the gas into the packed trains cars and within seconds, the first victims began dropping to floor, choking and vomiting.
