Tokyo marks 15th anniversary of subway gas attack

Tokyo subway workers observed a moment of silence Saturday to mark the 15th anniversary of a nerve gas attack by a religious cult, Japan's deadliest act of domestic terrorism.

About 20 employees at Kasumigaseki station in Tokyo's government district bowed their heads in silent prayer at 8 a.m., when members of the cult released sarin nerve gas in rush-hour trains on March 20, 1995. The five coordinated attacks killed 13 people and sickened 6,300 others.

Japanese Prime Minister Yukio Hatoyama joined victims and families in paying his respects, bowing deeply in front of an flower-laden alter.
