Those mortar rounds found by the Danish soldiers earlier this month turned out not to have any chemical weapons in them. A false alarm.
Frankly, I’m a bit surprised. They seemed to have a fairly high degree of confidence in the initial field tests. And it wouldn’t surprise if there were other shells that did have chemical munitions buried somewhere in the parts of Iraq that were combat zones during the Iran-Iraq war.
After all, many thousands of them were used at the time. And perhaps there was some situation (one can speculate in various directions) in which a small cache was buried as a crude means of battlefield disposal.
In any case, while it would be an important safety issue to dispose of such stuff properly, it would of course be irrelevant to the question of what weapons or weapons capacities Iraq maintained in 2002 and 2003.
