The US, which until two weeks ago had never provided any proof for its allegations, finally handed over its "evidence" of the Iranian origin of these weapons to the Iraqi government.  

Last week, an Iraqi delegation to Iran presented the US "evidence" to Iranian officials. According to Al-Abadi, a parliament member from the ruling United Iraqi Alliance who was on the delegation, the Iranian officials totally refuted "training, financing and arming" militant groups in Iraq.  

Consequently the Iraqi government announced that there is no hard evidence against Iran.  

but back in Iraq ….. 

“There was something interesting missing from Maj. Gen. Kevin Bergner's introductory remarks to journalists at his regular news briefing in Baghdad on Wednesday: the word "Iran," or any form of it. It was especially striking as Bergner, the U.S. military spokesman here, announced the extraordinary list of weapons and munitions that have been uncovered in recent weeks since fighting erupted between Iraqi and U.S. security forces and Shiite militiamen.  

Among other things, Bergner cited 20,000 "items of ammunition, explosives and weapons" reported by Iraqi forces in the central city of Karbala;  an additional Karbala cache containing 570 explosive devices, nine mortars, four anti-aircraft missiles, and 45 RPGs; and in the southern city of Basra alone, 39 mortar tubes, 1,800 mortars and artillery rounds, 600 rockets, and 387 roadside bombs. Read his remarks here. 

Not once did Bergner point the finger at Iran for any of these weapons and munitions, which is a striking change from just a couple of weeks ago when U.S. military officials here and at the Pentagon were saying that caches found in Basra in particular had revealed Iranian-made arms manufactured as recently as this year. They say the majority of rockets being fired at U.S. bases, including Baghdad's Green Zone, are launched by militiamen receiving training, arms and other aid from Iran. 

Iraqi officials also have accused Iran of meddling in violence and had echoed the U.S. accusations of new Iranian-made arms being found in Basra. But neither the United States nor Iraq has displayed any of the alleged arms to the public or press, and lately it is looking less likely they will. U.S. military officials said it was up to the Iraqis to show the items; Iraqi officials lately have backed off the accusations against Iran. 

A plan to show some alleged Iranian-supplied explosives to journalists last week in Karbala and then destroy them was canceled after the United States realized none of them was from Iran. A U.S. military spokesman attributed the confusion to a misunderstanding that emerged after an Iraqi Army general in Karbala erroneously reported the items were of Iranian origin. 

When U.S. explosives experts went to investigate, they discovered they were not Iranian after all.”
