Iranian warplanes fired at an unarmed U.S. drone in international airspace over the Persian Gulf last week but did not hit the aircraft, the Pentagon said Thursday, disclosing details of an unprecedented incident that triggered a formal warning to Tehran through diplomatic channels.
The Nov. 1 intercept was the first time Tehran had fired at an unmanned American aircraft, in a reminder of how tensions between the United States and Iran could escalate quickly into violence.
