US, UK hold joint drone drill in Persian Gulf

The U.S. Navy held a joint drone drill with the United Kingdom on Friday in the Persian Gulf, testing the same unmanned surveillance ships that Iran twice has seized in recent months in the Middle East.

The exercise comes as the U.S. Navy separately told commercial shippers in the wider Mideast that it would continue using drones in the region and warned against interfering with their operations.

The drones searched for a target on the seas, then sent the still images its cameras captured back to both the warships and the 5th Fleet's command center in the island kingdom of Bahrain.
