You may or may not have heard by now, but an artillery shell containing Sarin was found rigged to explode today. Here's the BBC:

An artillery shell containing a small amount of the nerve gas sarin has exploded in Iraq.

And in the same story:

However, a senior coalition source has told the BBC the round does not signal the discovery of weapons of mass destruction or the escalation of insurgent activity.

Got that? Coalition forces have found weapons of mass destruction, but this does not mean that they have found weapons of mass destruction.

Um.
