the Strait of Hormuz on Friday night, in a major escalation of tensions in the Gulf.” data-reactid=”29″>Two British oil tankers were seized by Iran’s Revolutionary Guards in the Strait of Hormuz on Friday night, in a major escalation of tensions in the Gulf.

The British-flagged Stena Impero had been en route to Saudi Arabia, but abruptly changed course and began sailing towards the Iranian island of Qeshm, data relayed by maritime tracking services showed.

The 30,000-tonne ship “went dark”, meaning its transponder was turned off, at 4.29pm UK time and nothing has been heard from her or her 23 crew since.

A second oil tanker, the British-operated, Liberian-flagged Mesdar, was intercepted by the Guards about 40 minutes after the course shift by Stena Impero, and was held for some time before being allowed to resume navigation. 

HMS Montrose, the Type-23 frigate, was understood to have been dispatched to help the Stena, but was minutes too late. 

Jeremy Hunt, the Foreign Secretary, said he was “extremely concerned by the seizure of two vessels by Iranian authorities in the Strait of Hormuz”. 

Mr Hunt said he was attending a Cobra meeting to determine the UK’s response and what could be done to secure their release, adding that the seizures were “unacceptable”. He said it was understood there were no British citizens among the two crews.

US President Donald Trump said Iran was showing its true colours and warned that it was in “big trouble”.  

Northern Marine, a Clyde-based subsidiary of the Stena Impero’s Swedish owner Stena AB, said a “hostile action” had preceded the vessel’s change of course on Friday afternoon. The company issued a statement saying it had been “approached by unidentified small craft and a helicopter during transit of the Strait of Hormuz while the vessel was in international waters”. 

Iran’s Revolutionary Guards said in a statement that they stopped the Stena Impero at the request of the maritime authority in the Iranian province of Hormozgan on suspicion that it had “violated international maritime law”, but did not elaborate. 

The head of Iran’s port authority was quoted by Guards-affiliated Tasnim news agency as saying: “We received reports of the British oil tanker, Stena Impero, causing problems, and therefore asked the military to guide the tanker towards Bandar Abbas harbour.”

They said the Mesdar, whose transponder was also turned off, was briefly held and cautioned about “environmental regulations” before it was let go.

Stena Bulk said the ship was “in full compliance with all navigation and international regulations.”

“There are 23 seafarers onboard of Indian, Russian, Latvian and Filipino nationality,” said Erik Hanell, president and chief executive of Stena Bulk. He said there had been no reported injuries.

Tracking data showed the Stena Impero was in the same area that a United Arab Emirates-based vessel was detained on Sunday and where a British vessel, the British Heritage, was blocked by Iranian forces earlier this month.

The move appeared to be in retaliation for Britain’s seizure of the Iranian Grace 1 tanker in Gibraltar earlier this month.

The fate of the tanker has been at the centre of escalating tensions between the UK and Iran and was seen as a pawn in the standoff between the Islamic Republic and the West.

Mr Hunt had hinted that the UK would release the ship if Iran promised its cargo would not go to the Syrian regime. The Foreign Secretary said talks with his Iranian counterpart, Mohammad Javad Zarif, had been productive. 

However, a court in Gibraltar on Friday extended for 30 days the detention of the vessel, which was carrying two million barrels of oil.

What has led to this seizure?

The seizure of the Stena Impero tanker in the Strait of Hormuz is the latest episode to contribute to rising tensions between the UK, US and Iran in the region.

Here is a timeline of recent incidents involving the three nations:

Government warns UK shipping to avoid Strait of Hormuz

After a COBR meeting this evening, the government is urging UK shipping the avoid the Strait of Hormuz region.

“We remain deeply concerned about Iran’s unacceptable actions which represent a clear challenge to international freedom of navigation.  We have advised UK shipping to stay out of the area for an interim period. 

“As the Foreign Secretary has said, our response will be considered and robust and there will be serious consequences if the situation is not resolved.

“We remain in close contact with our international partners and there will be further meetings over the weekend.”

Oil tanker was ‘in full compliance of regulations’

The British operator of the Stena Impero was in full compliance with all navigation and international regulations, a spokesman has said.

Iran’s state news agency IRNA quoted a military source as saying the vessel had turned off its tracker, ignored warnings from the Revolutionary Guards and was sailing in the wrong direction in a shipping lane.

“There are 23 seafarers onboard of Indian, Russian, Latvian and Filipino nationality,” said Erik Hanell, President and Chief Executive of the operator, Stena Bulk.

“There have been no reported injuries and the safety and welfare of our crew remains our primary focus.”

The ship “is no longer under the control of the crew and remains uncontactable”, he added.

Corbyn says Trump fuelled risk of conflict

Labour leader Jeremy Corbyn, responding to the seizure of two British tankers by Iranian forces, said: “The seizure of these vessels is unacceptable, and the tanker that remains under Iranian control must be released. Escalation risks a slide into an even deeper conflict.

“President Trump’s decision to tear up the Iran nuclear deal fuelled the risk of full-scale conflict.

“A negotiated reinstatement of the nuclear deal through the UN is essential to wind down tensions and defuse the threat of war in the Gulf.”

Stena Impero ‘surrounded by four vessels and helicopter’

Mr Hunt said the Stena Impero was surrounded by four vessels and a helicopter, and is heading into Iranian waters.

The second ship – the Mesdar – was surrounded by 10 speedboats, Mr Hunt told Sky, though said it was “not clear yet” whether it had changed course.

He said he had spoken to US secretary of state Mike Pompeo this evening about the situation and had tried to speak to Iranian foreign minister Mohammad Javad Zarif but he is on a plane.

“I will speak to him as soon as I can”, Mr Hunt said.

Hunt warns of  ‘serious consequences’

Mr Hunt warned there would be “serious consequences” if the situation is not resolved quickly. He told Sky News:

“We will respond in a way that is considered but robust and we are absolutely clear that if this situation is not resolved quickly there will be serious consequences.”

Asked if he could rule out military intervention, Mr Hunt said:

“We’re not looking at military options – we’re looking at a diplomatic way to resolve the situation – but we are very clear that it must be resolved.

“Freedom of navigation in the Gulf is absolutely essential. If that freedom of navigation is restricted, Iran is the biggest loser and so it is in their interest to resolve this situation as quickly as possible and we will do everything we can to do that.”

Tanker released?

Iran’s semi-official Tasnim news agency said Iran’s Revolutionary Guards had not captured the Mesdar.

“Despite reports, the ship has not been seized…and was allowed to continue its course after being warned about safety issues by Iranian forces,” the report said.

A spokesman for Norbulk Shipping UK confirmed the crew of the Mesdar are “safe and well” and the vessel has been “allowed” to continue its voyage.

Is it rash to sail through the Strait?

Sir Richard Dalton, former British ambassador to Iran, suggested the owners of the Stena Impero had been “rash” in sailing the tanker through the Strait of Hormuz.

Speaking to Sky News, he said Iran’s supreme leader Ayatollah Ali Khamenei had promised retaliation following the detention of Iran’s Grace 1 tanker in Gibraltar.

Sir Richard said:

“With hindsight, it’s easy to say that this was a somewhat reckless act by the owners, given that there was no British naval vessel in the vicinity.”

He said the Iranians had “lost their cool” despite recent “constructive discussions” over the Grace 1.

Sir Richard added:

“I don’t think the Iranians will continue to try to seize British vessels given they have got what they want, which is something to hold in a negotiation with Britain about their cargo held, they consider illegally, in Gibraltar.”

UK Chamber of Shipping calls for increased protection for vessels

Bob Sanguinetti, the CEO of the UK Chamber of Shipping, says: 

“We condemn unreservedly the capture of Stena Impero as she transited  the Strait of Hormuz earlier today.  The action by those involved is in violation of international regulations which protect ships and their crews as they go about their legitimate business in international waters.

“Our priority is for the safety and welfare of the crew.  We call on the UK Government to do whatever is necessary to ensure their safe and swift return.

“This incident represents an escalation.  Whilst we call for measured response, it is also clear that further protection for merchant vessels must be forthcoming to ensure enhanced security to guarantee free flow of trade in the region.”
