A classic example occurred when US forces destroyed a chemical munitions dump in Khamisiyah, Iraq in March 1991. The US Defense Department (DoD) initially denied the dangers but backtracked in 1997 after a UN Special Commission investigation proved that sarin gas had been released during the demolition.
Sarin is a deadly chemical weapon estimated to be over 500 times as toxic as cyanide. Non-lethal doses can create permanent neurological damage and symptoms such as loss of memory, paralysis, seizures and respiratory problems. Turns out that over eight metric tons of sarin were released during the Khamisiyah demolitions.
Previous research has linked sarin with brain cancer, and Freedom of Information Act requests indicate the Pentagon knew that up to 300,000 Desert Storm troops may have suffered from sarin exposure. Yet veterans seeking support were often told that their symptoms had no physical basis. MORE http://www.heatherwokusch.com/index.php?name=News&file=article&sid=119
