Japan on Monday marked 28 years since the Aum Shinrikyo cult's nerve gas attack on the Tokyo subway system that killed 14 people and injured over 6,000, at a time when another controversial religious group continues to draw public attention after the shooting of former Prime Minister Shinzo Abe.

At Kasumigaseki Station in the capital, officials observed a moment of silence during a memorial service at 8 a.m., around the time when the deadly sarin nerve agent was released in train cars on March 20, 1995.

Among those attending the event and also laying flowers was Shizue Takahashi, whose husband, a deputy stationmaster at Kasumigaseki Station, died in the incident.
