Captured documents confirm Iran backing for all sides against U.S. in Iraq

The U.S. military has found evidence that Iran helped train and equip Al Qaida's network in Iraq as well as Shi'ite insurgents.

The U.S. military has been analyzing Iranian intelligence memorandums and other reports that represent the strongest confirmation of long-standing assessments that Iran's Islamic Revolutionary Guard Corps is aiding both Sunni and Shi'ite insurgents in an effort to undermine Iraq and expel the U.S.-led coalition.

"The documents have been determined as authentic and provide the most detailed evidence of Iran's strategy in Iraq," an official said. "In short, Iran has been helping everybody, with the possible exception of the Saddam people, against us."

The U.S. military obtained the Iranian documents in December 2006 during the arrest of suspected Iranian intelligence commanders in Baghdad. The documents had been in possession of a suspected commander known only as Chizari. Chizari was captured inside a compound of Shi'ite leader Abdul Aziz Hakim, who earlier met President George Bush.
