Five Iranian Islamic Revolutionary Guard Corps gunboats tried to seize a British oil tanker in the Persian Gulf Wednesday but backed off after a British warship approached, a senior U.S. defense official told Fox News.
The British warship was said to have been less than 5 miles behind the tanker but soon intercepted the Iranian boats and threatened to open fire. A manned U.S. reconnaissance aircraft was above as well, the official said, adding that Iranian forces left without opening fire.
Navy Captain Bill Urban, spokesman for the U.S. Central Command (CENTCOM), said the military was aware of the reported actions. He added, “Threats to international freedom of navigation require an international solution. The world economy depends on the free flow of commerce, and it is incumbent on all nations to protect and preserve this lynchpin of global prosperity.”
The British frigate was identified as the HMS Montrose, according to The Sun. The vessel reportedly trained its 30mm deck guns on the enemy fleet and warned them off.
The incident was the latest in a series of provocations between the Islamic Republic and the West. British forces last week seized an Iranian supertanker that officials believed was operating in violation of European Union sanctions. The British Royal Marines captured the vessel in Gibraltar after believing it was trying to provide crude oil to Syria, an ally of Iran.
Iranian President Hassan Rouhani warned that Britain would face repercussions over the seizure.
Last month, Iran shot down a U.S. drone over the Strait of Hormuz, a vital waterway separating Iran from the United Arab Emirates. Oil exporters transport around 22 million barrels of oil per day through the strait.

Tensions between Iran and the U.S. have escalated in recent weeks and could spiral downward after Iran admitted Monday it surpassed uranium enrichment levels that were set by the Iran nuclear agreement in 2015.
President Trump pulled the U.S. out of the deal last year but several EU nations remained involved. Those countries -- Russia, China, Germany, France, Britain, and the European Union -- have called on Iran to stick to its commitments under the deal.
Iran has abandoned restraint in recent months as it seeks relief from U.S. sanctions. The republic has asked the deal's signatories to provide economic incentives in exchange for the de-escalation of its nuclear program.
Trump has indicated he will impose additional sanctions on Iran and urged those nations not to give in to its demands.
ROME — Forensic experts searching two 19th century tombs in the heart of the Vatican in hopes of solving the mystery of a teenage girl who vanished more than 30 years ago came up empty handed Thursday.
"They found nothing, not even the remains of those who were meant to officially be buried there," said the missing girl's brother, Pietro Orlandi. "I am relieved by it. They dug under one of the tombs and found a room underneath completely empty. In the other one they found a sarcophagus, also empty”
Emanuela Orlandi, the daughter of a Vatican bank employee, was 15 when she disappeared after leaving a music lesson in Rome in 1983. The teenager’s family believe her body could be buried in a tomb in a tiny cemetery inside the Vatican, after they received an anonymous tip last year.
“'If you want to find Emanuela, search where the angel looks," a tipster wrote in an unsigned letter posted alongside a picture of a statue of an angel in the Teutonic Cemetery, the family’s lawyer, Laura Sgrò, told NBC News.
Shortly before 8.15 (2.15 a.m. ET) on Thursday morning, the rector of the Teutonic College recited a prayer in front of the "tomb of the angel" and an adjoining tomb, Alessandro Gisotti, the director of the Vatican press office said in a statement. A 15-person team then began excavating the tombs of Princess Sophie von Hohenlohe and Princess Charlotte Frederica of Mecklenburg, who died in 1836 and 1840, respectively.
The Orlandi family had asked for the tomb under the statue of an angel holding a “rest in peace sign” to be opened, but the Vatican decided a second nearby tomb should also be excavated to “avoid misunderstandings,” Gisotti said.
This is not the first time a tomb has been opened in the mysterious case that has gripped Italy for more than three decades.
In 2005, an anonymous tipster claimed Orlandi's body was buried in the tomb of Enrico de Pedis, a criminal gangster who operated in Rome in the 1970s and 1980s, according to Giancarlo Capaldo, a state prosecutor who worked on the case between 2012 and 2016. In 2012 his tomb was finally opened, but Orlandi's remains were not found.
Pietro Orlandi earlier told reporters that after years of the Vatican not cooperating it appeared the Holy See was beginning to accept the idea that it may hold some responsibility for what happened. If his sister’s remains were found, Orlandi said he would expect the Vatican to open up an investigation into the murder and the concealment of the corpse.
“Now it’s not just us as a family, it seems also the Vatican wants to find out the truth about what happened,” he said.

Iranian boats tried to impede a British oil tanker near the Gulf - before being driven off by a Royal Navy ship, the Ministry of Defence has said.
HMS Montrose, a British frigate shadowing the tanker British Heritage, was forced to move between the three boats and the tanker, a spokesman said.
He described the Iranians' actions as "contrary to international law".
Iran had threatened to retaliate for the seizure of one of its own tankers, but denied any attempted seizure.
Boats believed to belong to Iran's Islamic Revolution Guard Corps (IRGC) approached British Heritage and tried to bring it to a halt as it was moving out of the Gulf into the Strait of Hormuz.
Guns on HMS Montrose were trained on the Iranian boats as they were ordered to back off, US media reported. The boats heeded the warning and no shots were fired.
The BBC has been told British Heritage - which is registered at the port of Douglas, in the Isle of Man - was near the island of Abu Musa when it was approached by the Iranian boats.
HMS Montrose had been shadowing British Heritage from a distance but came to its aid once the Iranian boats began harassing the tanker, BBC defence correspondent Jonathan Beale said.
Although Abu Musa is in disputed territorial waters, HMS Montrose remained in international waters throughout.
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.
"We are concerned by this action and continue to urge the Iranian authorities to de-escalate the situation in the region."
What does Iran say?
Quoting the public relations office of the IRGC's Navy, the Fars news agency said, in a tweet, the IRGC "denies claims by American sources" that it tried to seize British Heritage.
"There has been no confrontation in the last 24 hours with any foreign vessels, including British ones," the IRGC added, according to the AFP news agency.
Iranian foreign minister Mohammad Javad Zarif said the UK made the claims "for creating tension".
"These claims have no value," Mr Zarif added, according to Fars.
Last week, British Royal Marines helped the authorities in Gibraltar seize an oil tanker because of evidence it was carrying Iranian crude oil to Syria in breach of EU sanctions.
Iran also summoned the British ambassador in Tehran to complain about what it said was a "form of piracy".
On Wednesday, Iranian President Hassan Rouhani mocked the UK, calling it "scared" and "hopeless" for using Royal Navy warships to shadow another British tanker in the Gulf.
HMS Montrose had shadowed British tanker the Pacific Voyager for some of the way through the Strait of Hormuz, but that journey had passed without incident.
"You, Britain, are the initiator of insecurity and you will realise the consequences later," Mr Rouhani said.
The Royal Navy has a frigate, four minehunters and a Royal Fleet Auxiliary support ship already stationed in a permanent Naval Support Facility in the region, at Mina Salman in Bahrain.
This is enough to provide reassurance, but probably not to deal with a crisis, the BBC's Jonathan Beale said.
"HMS Montrose will not be able to provide protection for every commercial vessel in the Gulf with links to the UK," he added.
"Ministers will now have to contemplate sending another Royal Navy warship to the region. But in doing so, that may only further escalate tensions with Iran, which is something the government wants to avoid."
The UK has also been pressing Iran to release British-Iranian mother Nazanin Zaghari-Ratcliffe who was jailed for five years in 2016 after being convicted for spying, which she denies.
Could things get worse?
Iran appears to have been attempting to make good on its threat against British-flagged vessels in the wake of the seizure of an Iranian tanker off Gibraltar.
But though this incident has a specifically bilateral dimension, it is also a powerful reminder that the tensions in the Gulf have not gone away.
And with every sign that the dispute over the nuclear agreement with Iran is set to continue, things may only get worse.
The episode may add some impetus to US-brokered efforts to muster an international naval force in the Gulf to protect international shipping.
But most worrying of all, it shows that elements within the Iranian system - the Revolutionary Guard Corps's naval arm, or whatever - are intent on stoking the pressure.
This inevitably plays into President Trump's hands as Britain and its key European partners struggle to keep the nuclear agreement alive.
What about US-Iran relations?
The US has blamed Iran for attacks on six oil tankers in May and June.
The chairman of the US military's Joint Chiefs of Staff said, on Wednesday, it wants to create a multi-national military coalition to safeguard waters around Iran and Yemen.
The news followed the Trump administration's decision to pull out of an international agreement on Tehran's nuclear programme and reinforce punishing sanctions against Iran.
European allies to the US, including the UK, have not followed suit.
Majid Takht-Ravanchi told the BBC, Iran would move to the "third phase" of its stepped-up uranium enrichment programme unless the Europeans kept promises to uphold the economic benefits of the accord.

This latest row comes at a time of escalating tensions between the US and Iran.
The Trump administration - which has pulled out of an international agreement on Tehran's nuclear programme - has reinforced punishing sanctions against Iran.
Its European allies, including the UK, have not followed suit.
The UK has also been pressing Iran to release British-Iranian mother Nazanin Zaghari-Ratcliffe who was jailed for five years in 2016 after being convicted for spying, which she denies.
The US has accused Iran of a "crude and transparent attempt to extort payments from the international community" by violating the 2015 nuclear deal.
The US ambassador to the International Atomic Energy Agency said there was no credible reason for Iran to breach two key commitments on uranium enrichment.
Iran has said the steps were a response to the sanctions the US reinstated when it abandoned the deal last year.
It has vowed to reverse them if it is given compensation for economic losses.
European powers still party to the deal have set up a mechanism for facilitating legitimate trade without direct financial transactions that they hope will circumvent the US sanctions. However, Iran has said it does not meet its needs.
Iran's representative to the UN in New York told the BBC that the Europeans could do more, and that if they did not Iran would take further steps.
"If nothing happens in the next 60 days we will have to go to the third phase. The elements of the third phase are not known yet, but when it comes to that we will announce what we are going to do," Majid Takht-Ravanchi warned.
At Wednesday's special meeting of the IAEA board of governors in Vienna, diplomats were reportedly told that the global watchdog's inspectors had verified Iran was enriching uranium to 4.5% concentration - above the 3.67% limit set by the nuclear deal.
The country announced the step three days ago, saying it wanted to be able to produce fuel for the Bushehr nuclear power plant.
The IAEA was also said to have verified that Iran's stockpile of low-enriched uranium had grown since the 300kg (660lb) limit was exceeded on 1 July.
Low-enriched uranium, which typically has a 3-5% concentration, can be used to produce fuel for commercial nuclear power plants. Weapons-grade uranium is 90% enriched or more.
Experts have said the breach of the stockpile limit does not pose a near-term proliferation risk, but that enriching uranium to a higher concentration would begin to shorten Iran's so-called "break-out time" - the time required for it to produce enough fissile material for a bomb.
Iran insists it has never sought to develop a nuclear weapon. But the international community does not believe Iran, and negotiated a nuclear deal to prevent it from doing so.
US President Donald Trump said the deal did not go far enough to restrict Iran's nuclear programme and unilaterally withdrew from the accord in May 2018.
He wants to replace it with one that would also curb Iran's ballistic missile programme and its involvement in regional conflicts. But Iran has so far refused.
"Iran's current nuclear posture is clearly aimed at escalating tensions rather than defusing them, and underscores the serious challenges Iran continues to pose to international peace and security," she said.
"Such brinkmanship and extortion tactics will neither resolve the current impasse nor bring Iran sanctions relief. The path the regime is now on will only deepen its international isolation and raise the dangers it faces."
Ms Wolcott said it was imperative that Iran's "misbehaviour" not be rewarded.
"For if it is, Iran's demands and provocations will only escalate - as has happened all too often in the past," she warned.
Iran has long been secretly “enriching,” in total violation of the terrible 150 Billion Dollar deal made by John Kerry and the Obama Administration. Remember, that deal was to expire in a short number of years. Sanctions will soon be increased, substantially!
The ambassador called on Iran to reverse its nuclear steps and halt any plans for further advancements in the future.
"The United States has made clear that we are open to negotiation without preconditions, and that we are offering Iran the possibility of a full normalisation of relations," she added.
Iranian Foreign Minister Mohammad Javad Zarif said Iran's actions were "lawful" under the deal, which allows one party to "cease performing its commitments… in whole or in part" in the event of "significant non-performance" by other parties.
President Trump later alleged in a tweet that Iran had been "secretly 'enriching' uranium in total violation" of the deal made by his predecessor, Barack Obama, and promised that sanctions would "soon be increased, substantially".
Mr Trump did not give any further details. But the IAEA had repeatedly verified Iran's compliance with the deal until this month and Iran's ambassador to the agency, Kazim Gharib Abadi, said it had "nothing to hide."
Meanwhile, the top diplomatic adviser to French President Emmanuel Macron held talks in Tehran with Iranian officials to try to avoid further escalation.
Emmanuel Bonne was told by Iranian President Hassan Rouhani that Iran had "kept the path of diplomacy and talks completely open" and that it hoped other parties to the nuclear deal would be able to "use this opportunity properly".
