14th anniversary of Aum Shinrikyo's deadly 1995 sarin nerve gas attack on the Tokyo subway system was marked Friday in a ceremony at the Kasumigaseki subway station.

At 8 a.m., which is about the time the coordinated attack took place, two dozen Tokyo Metro Co. employees observed a moment of silence and a metro official offered flowers.

The March 20, 1995, attack was carried out by the top members of the doomsday cult, who released sarin at five stations on Tokyo's three central subway lines. The gas killed 12 people, including two subway workers at Kasumigaseki Station, and sickened more than 5,500 others.

"In the past 14 years, we've been striving not to let this tragedy fade away, and we will continue our efforts," said Shizue Takahashi, 62, who lost her husband, a subway employee, at Kasumigaseki Station.

A 54-year-old public servant from Chiba Prefecture who was injured in the attack said he never misses the March 20 observance.
