Up to 2.4 million people could be killed or injured in a terrorist attack on a U.S. manufacturer of toxic chemicals if the plant was located in a densely populated area, according to a recently released report by the Army surgeon general.
The report, dated October 29, 2001, ranked the threat of attacks against chemical plants second only to widespread use of biological weapons, such as contaminating the country's water or food supply, which could result in as many as 4.18 million casualties.
