Dukaczewski said the find was made "outside the country" and that it was "hot business", but declined to give more details.

Poland has deployed WSI officers in Iraq to protect its armed contingent there.

Poland, which is in charge of one of four administrative zones in Iraq, has already sent about 100 troops there with another 250 on their way, presently in Kuwait.
