500 mortar rounds were uncovered with liquid chemicals inside....ever wonder what the easiest way to deliver chemical warfare is? Ever wonder how they hit enemy trenches with chemical weapons in WWI? Mortar shells. There is only one reason for putting chemicals in mortar rounds. Doesn't seem as shocking as a big nuke with a radioactive symbol painted on the side; and WMD marked on it; but it's real.....and even if the damage level was not high enough to constitute the media's definition of a WMD.
