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 rules-based system of the international community," Foreign Secretary Dominic Raab told media.
"You cannot go about detaining unlawfully foreign vessels."
