US warns Iran of retaliation over Iraq action

America's top military officer has ratcheted up the pressure on Iran by issuing an unusual public warning that the Pentagon is planning for “potential military courses of action”.

Admiral Mike Mullen, chairman of the joint chiefs of staff, blamed the Iranian government and Quds force of the Iranian Revolutionary Guard for its “increasingly lethal and malign influence” in Iraq. He said conflict with Iran would be “extremely stressing” for America’s overstretched forces, but added: “It would be a mistake to think that we are out of combat capability.”

Mullen said he was increasingly concerned about Iran’s growing involvement in supplying munitions and training to rebel Shi’ite militias and “killing American and coalition soldiers in Iraq”.

Speaking at a Pentagon news conference late on Friday, he said recent operations in the southern port city of Basra had revealed “just how much and how far Iran is reaching into Iraq to foment instability”. A Pentagon source said the admiral’s frankness was “extremely significant” and could pave the way for some form of attack on Iran. However, Mullen said: “The solution right now still lies in using other levers of national power, including diplomatic, financial and international pressure.”

Mullen’s tough rhetoric came shortly after General David Petraeus, the US commander in Iraq responsible for the troop surge, briefed Congress about the “nefarious activities” of the Quds force in stirring violence in Iraq. There were a total of 923 civilian deaths in Iraq last month, the highest number since August 2007. The Sunday Times
