(Makes me wonder if the world isn't heading for World War III. I believe Russia backs Iran.)

Iran’s top paramilitary force appeared to take responsibility for a missile attack early Sunday that slammed into northern Iraq, sending U.S. troops rushing for shelter, shattering windows and creating new complications for diplomatic efforts to ease tensions with Tehran.

The Islamic Revolutionary Guard Corps issued a statement through its official Sepha News site saying that it carried out a missile attack in response to recent Israeli actions in the region, which included an airstrike last week in Syria that killed two of the Iranian paramilitary group’s commanders.
