US general says no proof Iran behind Iraq arms contrary to what Bush and Rumsfeld have said

The top U.S. military officer said on Tuesday the United States does not have proof that Iran's government is responsible for Iranians smuggling weapons and military personnel into Iraq.

President George W. Bush said on Monday components from Iran were being used in powerful roadside bombs used in Iraq, and Defense Secretary Donald Rumsfeld said last week that Iranian Revolutionary Guard personnel had been inside Iraq.

Asked whether the United States has proof that Iran's government was behind these developments, Marine Corps Gen. Peter Pace, chairman of the military's Joint Chiefs of Staff, told a Pentagon briefing, "I do not, sir."
