A U.S. Army officer picks up a piece of evidence gathered by the U.S. Military which is claimed to show Iran's support to militant Iraqis fighting U.S. forces at a news conference in Baghdad February 14, 2007. The U.S. military in Iraq on Wednesday seemed to distance itself from comments made by a U.S. defence official at the weekend that implicated the "highest levels" of Tehran's government in arming Iraqi militants.
