As the country moves to increase the safety of railways following a string of recent random attacks on passengers, Japan marked the 27th anniversary Sunday of the nerve gas attack by the Aum Shinrikyo cult in the Tokyo subway system that killed 14 people and injured over 6,000.

Tokyo Metro Co. officials and relatives of the victims observed a moment of silence at a memorial service at Kasumigaseki Station at 8 a.m., around the time when the deadly sarin nerve agent was released in train cars on March 20, 1995.

The doomsday cult's founder Shoko Asahara, who masterminded the attack, and 12 of his former followers were put to death in 2018.
