The Wall Street Journal is reporting an American military raid in southern Iraq uncovered a makeshift factory used to construct advanced roadside bombs that the U.S. had previously claimed were made only in Iran. The Saturday raid in the small town of Jedidah marked the first time U.S. forces found evidence that militants inside Iraq are assembling “explosively formed penetrators,” or EFPs. Until now, the U.S. military was claiming that Iran was directly supplying Shiite militants with EFPs, which can punch through the armored shells of U.S. military vehicles. On Monday, U.S. military commanders displayed weapons and explosives seized in the raid that they claimed had markings indicating they had originated from Iran. However, The New York Times reports the military included several items that were obviously not from Iran. One box of plastic PVC tubes said the tubes had been made in the United Arab Emirates. Another box containing plastic read “made in Haditha” — a Sunni town in Iraq.
