Iran’s Islamic Revolutionary Guard Corps was chuffed on Thursday morning when it announced it had downed a US drone. It had tracked the drone from the southern part of the Persian Gulf, an IRGC statement said at Fars News. The drone was carrying out an “espionage” mission, Tehran said. When the drone entered Iran’s “territory” it was targeted and “defeated’ by the IRGC.It is a “$200 million giant,” the IRGC says, of the drone they brought down. Not since the Russians shot down a U-2 spy plane in 1960, or when Iran hacked into a US RQ-170 Sentinel drone in 2011 and landed it safely in Iran, has a foreign power presented the US with such an aerial embarrassment.
