LONDON—Britain told Iran on July 29 that if it wants to “come out of the dark” it must follow international rules and release a British-flagged oil tanker seized by its forces in the Gulf.
Iranian commandos seized the Stena Impero near the Strait of Hormuz, the world’s most important waterway for oil shipments, on July 19. That was two weeks after British forces captured an Iranian oil tanker near Gibraltar accused of violating sanctions on Syria.
