Saddam was supposed to have (a) destroyed all of his chemical munitions,
and
(b) accounted for same. It is obvious that in this case (a) any
destruction
was unintentional (or why would they have wrapped them up before burying
them?), and (b) he did not account for them. That would put him in
violation
of both the ceasefire agreements and the subsequent UN resolutions.

The rounds were found from former swamp bed (Saddam dried these swamps in
effort to catch the Shiia rebels after 1991) and were estimated to be 10+
years old by US specialists.
