Japan on Saturday marked the fourth anniversary of the deadly nerve gas attack on the Tokyo subway system amid fears about a resurgence of the doomsday cult responsible.
Victims of the gas attack, which killed 12 people and made 5,300 ill, submitted a petition to the government asking it to monitor the health and mental condition of those stricken in the incident and to keep a close eye on the Aum Shinri Kyo cult.
The victims also pressed demands for full compensation, saying they had been compensated for only 20 percent of the claims lodged against the cult.
Subway workers marked the anniversary with a solemn ceremony at Kasumigaseki Station in central Tokyo, where two subway workers died on March 20, 1995, while trying to remove a bag containing the nerve gas sarin from a morning rush hour commuter train.
Leaders of the Aum Shinri Kyo cult are on trial for crimes including the subway attack.
