Japan marked the 24th anniversary Wednesday of a deadly sarin nerve gas attack on Tokyo's subway system carried out by the Aum Shinrikyo cult, which killed 13 people and injured more than 6,000 others.

In a memorial ceremony at Kasumigaseki Station, relatives of the victims and employees of the subway operator observed a moment of silence at 8 a.m., around the time when the attack occurred on March 20, 1995.

The doomsday cult's founder, Shoko Asahara, and several of his former followers were executed for the crime last July.
