Iran fired on US drone in Gulf: US

The Pentagon revealed Thursday that two Iranian fighter jets fired on an unarmed US Predator drone in the Gulf last week but the aircraft was not hit, in an incident that underscored tensions in the region.
The incident occurred on November 1 -- less than a week before America's presidential election -- but the Pentagon kept it quiet until reports of the confrontation leaked out.
It was unclear whether the Iranians intended to warn off the unmanned drone.
