The brutal face of modern day terrorism bared its fangs recently on a busy subway system in Tokyo. On March 20, a vicious nerve gas spewed through subway cars and stations during the morning rush hour in the city leaving 6 dead and thousands of passengers reeling under its noxious effects.

The toxic agent was believed to be the nerve gas sarin, which can be lethal even at a dose of 0.01 mg per kilo of human body when absorbed through the skin or inhaled. Japanese authorities said that the substance was deliberately planted in parcels in at least 5 subway cars on 3 train lines.

An official investigation is underway to hunt down the culprits. "We can't allow this kind of indiscriminate murder of innocent citizens," asserted Japanese Prime Minister Tomicchi Muryama.
