A U.S. military drone has been shot down in international airspace over the Strait of Hormuz by an Iranian surface-to-air missile, a U.S. official said on Thursday, speaking on condition of anonymity.

The official said the drone was a U.S. Navy MQ-4C Triton. No further details were immediately available, including the time of the shoot-down. The aircraft's manufacturer, Northrop Grumman, says on its website that the Triton can fly for over 24 hours at a time, at altitudes higher than 10 miles, with an operational range of 8,200 nautical miles.
