A deputy commander in Iran’s Revolutionary Guards warned Britain that ‘the enemy will regret detaining our oil tanker’ on Thursday, a day after three Iranian vessels tried to seize a British tanker near the Persian Gulf.
The same commander also said that retaliatory actions will be announced against Britain soon, without giving further details.
The UK government says that three armed boats belonging to the Revolutionary Guards ordered UK tanker British Heritage to divert and stop as it tried to pass through the Strait of Hormuz – a strategic bottleneck near Iran – on Wednesday.
The HMS Montrose, a Royal Navy frigate escorting the Heritage, placed itself between the tanker and the Iranian vessels, trained its guns on them, and ordered them to back off – which they did, the UK said.

The British tanker was travelling through the Strait of Hormuz, a strategic bottleneck that sits partially in Iranian waters, when the vessels approached and ordered it to stop

The Iranian boats complied without a shot being fired.
Iran has been threatening to seize a British tanker in retaliation after the UK stopped one of its vessels – the Grace 1 – off the coast of Gibraltar last week.
A UK government spokesman said: ‘Contrary to international law, three Iranian vessels attempted to impede the passage of a commercial vessel, British Heritage, through the Strait of Hormuz.
‘HMS Montrose was forced to position herself between the Iranian vessels and British Heritage and issue verbal warnings to the Iranian vessels, which then turned away.
‘We are concerned by this action and continue to urge the Iranian authorities to de-escalate the situation in the region.’
According to The Sun, an anonymous officials added: ‘The Royal Navy HMS Montrose, which was also there, pointed it guns at the boats and warned them over radio, at which point they dispersed.’
another said: ‘It was harassment and an attempt to interfere with the passage.’
American aircraft were also overhead at the time and filmed as the Iranian vessels approached and then backed off, according to CNN.
Iran denied that it had attempted to seize the vessel, rebuffing ‘claims by American sources.’
‘There were no clashes with alien boats, especially English boats,’ the Fars news agency, which is linked to the Revolutionary Guards, said.
Iranian Foreign Minister Mohammad Javad Zarif dismissed the British report as ‘worthless’, according to the semi-official Fars news agency.
A spokesman for BP, which operates the British Heritage tanker, said: ‘Our top priority is the safety and security of our crews and vessels. While we are not commenting on these events, we thank the Royal Navy for their support.’
It is understood the ship was not carrying cargo.
UK officials had previously confirmed that the Montrose was in the region performing a ‘maritime security role.’
It comes after Royal Marines seized an Iranian oil tanker off the coast of Gibraltar last week, which Britain says was violating EU sanctions by carrying fuel to Syria.
Iran denies the vessel was bound for Syria and says the UK acted on behalf of the United States, which has separate sanctions in place against Tehran itself.

Tensions around the Persian Gulf have been ratcheting up since the US tore up a nuclear pact signed with Iran last year, but have reached fever-pitch since a series of attacks on oil tankers and the shoot-down of an American drone

Iranian President Hassan Rouhani warned earlier on Wednesday that Britain would ‘face consequences’ for detaining an Iranian tanker near Gibraltar
Senior Iranian politicians had threatened to retaliate by seizing a British tanker.
Iran’s President Hassan Rouhani said in a cabinet session earlier on Wednesday that Britain would ‘see the consequences’ after the Gibraltar seizure.
In remarks broadcast on Iranian TV, Rouhani said: ‘You (Britain) are the initiator of insecurity and you will realise the consequences later.
‘Now you are so hopeless that, when one of your tankers wants to move in the region, you have to bring your frigates (to escort it) because you are scared.
‘Then why do you commit such acts? You should instead allow navigation to be safe.’
The HMS Montrose is equipped on the deck with 30 mm guns specifically designed to drive off small boats.
It is understood to have approached from the rear of the British tanker and aimed its weapons at the Iranians before issuing a verbal warning.
The Montrose, based in Bahrain, also has radar that allows it to track aircraft and missiles up to 120 miles away, and a missile system with a 20-mile range.
The BP-owned British Heritage, had earlier halted to take refuge off the coast of Saudi Arabia following Iran’s threat.
Registered at the port of Douglas, in the Isle of Man, the ship is operated by BP usually with a crew of around 25 people.
HMS Montrose has also been in the region since April as part of a three-year deployment supporting counter-terror and anti-smuggling work.
The Royal Navy has had a continuous presence in the region for more than 30 years following the Iran-Iraq war in 1980 in what is known as Operation Kipion.

Britain has accused Iran of attempting to sail oil to Syria, in breach of EU sanctions against the country which came into force in 2011 (pictured, Marines sail near the Grace 1 tanker)
Earlier this week, British tanker Pacific Voyager, which sails under the Isle of Man flag, was escorted through the Strait of Hormuz by HMS Montrose, a Type-23 frigate, on Tuesday.
The incident on Wednesday took place against the backdrop of rising tensions between the Iran and the US which saw Donald Trump accuse the Middle Eastern nation of attacking several tankers in the Gulf.
A number of tankers in the Strait have been damaged by explosions in recent months – which the UK and US blamed on Iran – and Iran shot down a US drone.
America has begun making plans to enlist allies over the next two weeks into a military coalition to safeguard strategic waters off Iran.
Under the plan, which has only been finalized in recent days, the United States would provide command ships and lead surveillance efforts for the military coalition. Allies would patrol waters near those U.S. command ships and escort commercial vessels with their nation’s flags.
Marine General Joseph Dunford, the chairman of the Joint Chiefs of Staff, articulated those details to reporters following meetings on Tuesday about it with acting U.S. Defense Secretary Mark Esper and Secretary of State Mike Pompeo.
‘We’re engaging now with a number of countries to see if we can put together a coalition that would ensure freedom of navigation both in the Straits of Hormuz and the Bab al-Mandab,’ Dunford said.
‘And so I think probably over the next couple of weeks we’ll identify which nations have the political will to support that initiative and then we’ll work directly with the militaries to identify the specific capabilities that’ll support that.’

Four oil tankers in the Gulf were sabotaged in May, before another two were attacked in June (pictured). America and the UK have blamed the attacks on Iran

The US subsequently released footage of what it claims shows Iranian forces returning to one of the tankers to remove an unexploded limpet mine from its hull

Iran shot down a US RQ-4 Global Hawk drone, prompting Donald Trump to order airstrikes in retaliation, which he then called off at the last minute
