EAST OF BAQUBA, Iraq, Oct 7 (Reuters) - The U.S. military commander in Iraq stepped up accusations over the weekend that Iran was stoking violence in Iraq and said Tehran's ambassador to Baghdad was a member of the Revolutionary Guards Qods force. Washington accuses the elite unit of Iran's Revolutionary Guards of inciting bloodshed in Iraq and of training and equipping militias who have attacked U.S. troops. General David Petraeus, speaking at a U.S. military base about 30 km (20 miles) from the Iranian border on Saturday, said Iran was giving advanced weaponry to militias in Iraq.
