A large British-flagged vessel has transited the Strait of Hormuz in the first such passage made by a UK ship since Iran seized the Stena Impero tanker last week.
Iran has warned the UK not to enter a “dangerous game” as plans to relieve a Royal Navy warship in the Gulf were escalated amid escalating tensions.
Tensions in the Gulf make the case for strengthening the Royal Navy, Foreign Secretary Jeremy Hunt said.
Police in Gibraltar have arrested the captain and chief officer of the Iranian supertanker detained last week in an operation involving British Royal Marines.
The Royal Navy has driven off three Iranian vessels which tried to stop a commercial tanker from travelling through the Strait of Hormuz.
