Iran’s Islamic Revolutionary Guard Corps (IRGC) has released footage it says shows the downing of a U.S. MQ-1 drone early Sunday, fueling a growing confrontation between Tehran and Washington. Iranian officials claim the aircraft was operating inside Iranian territorial waters when it was intercepted, presenting the incident as a defense of national sovereignty, while U.S. Central Command flatly disputes that account and insists the drone was flying over international waters at the time it was shot down.
