Poland said its soldiers found 17 Grad rockets and two mortar shells  in late  June and said U.S. experts had carried out tests on the  weapons.                          

Poland said it "purchased" the shells through individuals who  contacted army  officials in its military zone in south-central  Iraq.

"We bought all the shells available ... Terrorists are  seeking these missiles  on the black market, offering a price of  around $5,000 per warhead," Dukaczewski  said, adding that Poland  had no evidence that any chemical weapons fell into  such hands.

Poland said its soldiers found 17 Grad rockets and two mortar shells  in late  June and said U.S. experts had carried out tests on the  weapons.

... the U.S. military said only two of the rockets had tested positive  for sarin  gas, and another 16 of the rockets found by the Poles  had contained no chemical  agents. The reason for the discrepancy  in numbers was unclear.

In Baghdad, the U.S. military issued a statement saying that two  122 mm rockets  found by Polish forces had tested positive for  sarin gas and confirmed that they  were left over from the Iran-Iraq  war, but said they posed little danger.

These are the weapons of mass destruction? And how come the O in WOMD has been dropped?
