LONDON—In an audio recording released July 21, a British naval officer insists that a British-flagged oil tanker must be allowed to sail through the Strait of Hormuz as Iranian paramilitary forces demand that the vessel change course before commandeering it.
The audio, released by maritime security risk firm Dryad Global, shows how the British navy was unable to prevent the ship’s seizure Friday by Iranian Revolutionary Guard forces. The seizure has prompted condemnation from the UK and its European allies as they continue to call for a de-escalation of tensions in the critical waterway.
