NEW YORK — Tests of the artillery shell that detonated in Iraq on Saturday have confirmed that it did in fact contain an estimated three or four liters of the deadly sarin (search) nerve agent, Defense officials told Fox News Tuesday.
The artillery shell was left as a roadside bomb, the U.S. military said Monday. Two U.S. soldiers were treated for minor exposure to the nerve agent when the 155-mm shell exploded before it could be rendered inoperable.
The soldiers displayed "classic" symptoms of sarin exposure — most notably dilated pupils and nausea, officials said. The symptoms ran their course fairly quickly, however, and as of Tuesday, the two had returned to duty.
Was it straight sarin or a binary agent (where two chemicals mix to form sarin)? Binaries are much safer to handle of course. According to at least one blogger, Iraq had declared that it did not have binary sarin in artillery shells.
My guess, given the limited symptoms, was that it was binary. Some mixing occurred and a small amount of sarin was released, but a shell with 3-4 liters of straight sarin would likely have killed anyone exposed to it.
