Britain warns Iran: release ship to "come out of the dark"

Britain on Monday warned Iran that if it wants to "come of the dark" then it must follow international rules and release a British-flagged vessel seized by the Islamic Republic in the Gulf.

"If the Iranians want to come of the dark and be accepted as a responsible member of the intentional community they need to adhere to the rules-based system of the international community," Foreign Secretary Dominic Raab told Sky News.

"You cannot go about detaining unlawfully foreign vessels."
