There was a entry over at antiwar.com by an Iraqi-American from the Minnie area, who owns the ME restaurant Sinbads who visited Iraq and mentioned things like this occurring. Only he went further and said some US Marines were shot at by men driving American vehicles, who spoke perfect English. He said they wore masks. I don't how true it is but this story seems to give some credence to it.
“The power to declare war, including the power of judging the causes of war, is fully and exclusively vested in the legislature.” ~ James Madison, Father of the Constitution
