The stories I saw about the shells said they were old.
They were apparently from the Iran-Iraq war timeframe. E.g. [link|http://news.bbc.co.uk/2/hi/middle_east/3722255.stm|BBC].
WND has very little credibility with lots of people. E.g. [link|http://z.iwethey.org/forums/render/content/show?contentid=59950|this] thread that started with a WND article.
Let's see what the actual ISG reports say. :-)
Cheers,
Scott.
