We are still not calling this a chemical weapons site...
We don't want to let the cat out of the bag just yet because we don't want to invite the Iraqi's to use the other WMD that they are still in control of.
I suspect that as more of the civilian areas of Baghdad come under American and British control, then you will hear more of the chemicals that we have found.
We don't want to give Sadam's thugs a chance to inflict a chemical scorched earth policy as they attempt to retreat from Baghdad towards Tikrit.
