USNews.com: Nation & World: Exclusive: Iranians Had Showdown With U.S. Forces

Why are these Iranians allowed to attack US troops in Iraq and walk away? Why were the Iraqis content to sit there and watch? Where did the missing Iraqis go?

Why do I have a feeling that some of the Shia border guards are working with the Iranians?

USNews.com: Nation & World: Exclusive: Iranians Had Showdown With U.S. Forces: "As the British government demanded the immediate release of 15 of its sailors whose boats were seized by Iranian naval vessels in the Persian Gulf on Friday, U.S. News has learned that this is not the first showdown that coalition forces have had with the Iranian military.

According to a U.S. Army report out of Iraq obtained by U.S. News, American troops, acting as advisers for Iraqi border guards, were recently surrounded and attacked by a larger unit of Iranian soldiers, well within the border of Iraq.

The report highlights the details: A platoon of Iranian soldiers on the Iraqi side of the border fired rocket-propelled grenades and used small arms against a joint patrol of U.S. and Iraqi soldiers east of Balad Ruz. Four Iraqi Army soldiers, one interpreter, and one Iraqi border policeman remain unaccounted for after the September incident in eastern Diyala, 75 miles east of Baghdad.

During a joint border patrol, both American and Iraqi soldiers saw two Iranian soldiers run from Iraq back across the Iranian border as they approached. The patrol then came upon a single Iranian soldier, on the Iraqi side of the border, who did not flee.
