I believe that it came from an embedded reporter with the Pittsburgh Tribune-Review.

"After a quick inspection at what military authorities call the 'Yellowcake Facility' a few hundred meters offsite, the Army specialists told the Marines they suspect Al-Tuwaitha harbors weapons-grade plutonium."

Thanks for the link. The original story I saw earlier didn't mention that (it went on more about the difficulty of creating the underground complex in the first place).

Interestingly, the later, similar story by the same reporter downplays the plutonium report, and has dropped the words "weapons-grade" from what the Army specialists told the Marines.
