LONDON — A British warship tried with out success to cease Iran’s seizure on Friday of an oil tanker close to the Strait of Hormuz, an audio recording of the episode released on Sunday shows, underscoring the perils to Persian Gulf transport and the worldwide economic system throughout escalating tensions between Iran and the West.

“In case you obey, you may be secure,” an English-speaking officer from the Islamic Revolutionary Guards Corps of Iran says in a radio name to the tanker, Stena Impero, which was crusing underneath a British flag. “Alter your course to 360 levels instantly, over.”

In one other radio name, a Royal Navy officer aboard the British warship Montrose tells the tanker to remain its course.

“That is British warship foxtrot 236,” the officer says within the recording. “Sir, I reiterate that as you’re conducting transit passage in a acknowledged worldwide strait, underneath worldwide legislation your passage should not be impaired, impeded, obstructed or hampered. Please affirm that you’re conducting transit passage in a acknowledged worldwide strait.”

The British mentioned days earlier that the identical warship, the Montrose, had inserted itself in entrance of a gaggle of Iranian boats to efficiently deter their try to seize one other British-owned tanker. However on Friday, British officers mentioned, the Montrose was too removed from the Stena Impero to succeed in it in time.

In a separate video launched by the semiofficial Iranian information company Fars, small Iranian boats will be seen surrounding the Stena Impero. An Iranian helicopter flies above it, and several other troopers in black masks descend from the helicopter to take management of the tanker.

The audio of the seize, launched by the maritime safety agency Dryad International, illustrates the difficultly for even the comparatively formidable British Navy in defending ships passing the Iranian coast by means of the Strait of Hormuz. A fifth of the world’s crude oil provide is carried by means of the slender strait, a serious choke level on the neck of the Persian Gulf.

America has talked of sharing intelligence and coordination to assist different nations defend their business vessels passing by means of the gulf. However Washington has made clear that its function could be restricted and that different nations should assist shoulder the burden.

The recording could bolster British claims concerning the location of the ship in the mean time of its seize, although it’s attainable that the naval officer was not talking precisely about its location. The proprietor of the tanker, Stena Bulk, has mentioned that it was in worldwide waters on the time it was seized, and on Saturday, British officers mentioned the ship was in Omani waters.

Iran has mentioned that the tanker was crusing by means of Iranian waters, and has provided completely different explanations for its seizure, together with that it had been polluting the gulf or had collided with an Iranian fishing boat.

Iranian officers, nevertheless, have additionally described the seizure as retribution for the British impounding of an Iranian tanker off the coast of Gibraltar on July four. Britain has mentioned that it stopped that tanker on suspicion that it had been violating a European Union embargo on the supply of oil to Syria.

Iran has referred to as that seizure an act of piracy directed by Washington as a part of a strain marketing campaign in opposition to Tehran.

Britain’s overseas secretary, Jeremy Hunt, this weekend referred to as the trade a tanker “tit for tat.” However additionally it is half of a bigger confrontation between Washington and Tehran over a 2015 settlement between world powers and Iran to restrict the nation’s nuclear program, which Western governments have feared would possibly allow Iran to supply a nuclear weapon.

President Trump final 12 months pulled the USA out of the settlement, vowing to power Iran to undergo extra onerous and everlasting restrictions on its typical navy and regional insurance policies, in addition to on its nuclear program.

The accord had promised Iran reduction from financial sanctions in trade for suspending and dismantling a lot of its nuclear program, however in Might, Mr. Trump put in place sweeping new sanctions aimed toward chopping off all exports of Iranian oil. The penalties have plunged the Iranian economic system into disaster, and Iranian officers have described Mr. Trump’s strikes as financial warfare.

Iran has responded with rigorously calibrated steps to restart its nuclear program. However it has additionally flexed its navy muscular tissues, pointedly warning the world of its potential capability to strangle the passage of oil by means of the Strait of Hormuz.

America has accused Iran of utilizing naval mines to break six tankers in two assaults within the Persian Gulf, and Tehran has boasted of capturing down an American surveillance drone.

America got here inside minutes of a missile strike in retaliation for the downing of the drone earlier than Mr. Trump referred to as the assault off, and final week, the USA mentioned it had shot down an Iranian drone that had approached an American warship.

Along with a reciprocal retaliation for the seizure of the Iranian tanker, the seize of the British tanker appeared to suit a bigger Iranian technique. Tehran has sought to boost the price to the world powers of their efficient failure to ship on the guarantees of the 2015 nuclear accord due to the American sanctions. The rising trade of threats has pushed up oil costs and raised fears new navy battle could escape within the area.

Though Mr. Trump has signaled a willingness to barter a extra restricted decision to the standoff over the renegotiation of the nuclear accord, Secretary of State Mike Pompeo on Saturday reiterated the administration’s calls for that the Iranians “basically change the path of their nation.”

If the Iranian authorities decides “to behave like a standard nation,” Mr. Pompeo mentioned throughout an look in Ecuador, “we’re ready to barter throughout a broad spectrum of points with no preconditions.”

However, he added, “We have now seen no indications that the Iranians are ready to basically change the path of their nation, to do the issues we’ve requested them to do with their nuclear program, their missile program, their malign habits around the globe.”

Even earlier than the tanker seizure, Britain occupied a pivotal place within the impasse over the nuclear accord as a result of it’s the European nation most hawkish towards Iran and most sympathetic to Washington.

Britain, France, Germany and the European Union all signed the 2015 settlement, and all have damaged with the Trump administration to attempt to protect it. Britain joined its European allies in making an attempt to assemble an alternate buying and selling platform that will enable the Iranians to bypass the American-linked world monetary system and keep away from the excellent new sanctions.

The tanker seize is, due to this fact, a dangerous gambit for Iran. It may push Britain nearer to becoming a member of the USA in reimposing sanctions. That will just about eradicate any hope of preserving the prevailing nuclear accord, even when in 2020 the USA elected a brand new president who sought to return to the deal.

For the second, Britain is all however paralyzed by adjustments in its personal management. Prime Minister Theresa Might is predicted to resign on Wednesday. A contest inside the Conservative Get together to succeed her is underway however has not but concluded. And the favourite to win is the famously brash and unpredictable Boris Johnson.

Mr. Johnson, a former mayor of London and a former overseas minister, has mentioned that he would search to keep away from a confrontation with Iran. However he has risen by means of his occasion largely by railing in opposition to Europe and has just lately sought nearer ties to Mr. Trump. Mr. Johnson was a pacesetter of the marketing campaign for Britain to exit the European Union, and because the Oct. 31 departure date approaches, he has steered that improved commerce with the USA may make up for any losses on the European facet.

Mr. Hunt, the overseas minister, occurs to be Mr. Johnson’s competitor in the runoff within the management contest. That has put a query mark over Mr. Hunt’s long-term future within the job, whether or not he ascends to be prime minister or is changed underneath Mr. Johnson.

Every week earlier than the seize of the tanker on Friday, Mr. Hunt tried to scale back tensions with Tehran by suggesting that Britain may “facilitate” the discharge of the captured Iranian tanker in Gibraltar if proof had been to indicate that tanker had not been headed to Syria.

A court docket determination on Friday in Gibraltar, nevertheless, seems to have postponed that chance. A choose ordered the continued detention of the ship till at the least Aug. 15, pending one other listening to.
