Sarin gas attack on the Tokyo subway

In 1995, an obscure Japanese religion launched a chemical attack on the Tokyo metro.

Members of the doomsday cult, which called itself Aum Shinrikyo, dropped plastic bags containing sarin liquid on the floors of five different trains and then pierced them. As the liquid evaporated, passengers began inhaling the deadly fumes. Thirteen people were killed and thousands more injured.

One of the passengers affected that day was Atsushi Asakahara. He spoke to Chloe Hadjimatheou in 2012.
