Iran attempted to block British oil tanker – claim


Three Iranian vessels tried to block the passage of a BP-operated tanker through the Strait of Hormuz but withdrew after warnings from a British warship, the British government said.

The stand-off followed a warning by US President Donald Trump that US sanctions on Iran would be “substantially” increased as part of Washington’s drive to curb Iran’s nuclear activities and regional behaviour.

Britain urged Iran to “de-escalate the situation in the region” after the incident involving British Heritage, operated by BP under an Isle of Man flag.

“HMS Montrose was forced to position herself between Iranian vessels and British Heritage and issue verbal warnings to the Iranian vessels which then turned away,” a British government spokesman said in a statement.

The incident came almost a week after British Royal Marines boarded an Iranian tanker, the Grace 1, off Gibraltar and seized it on suspicion of breaking EU sanctions by taking oil to Syria.

Iran’s armed forces chief of staff, Major General Mohammad Bagheri, said the British seizure would not go unanswered but the Islamic Republic denied it wanted to stop the British Heritage.

Iranian Foreign Minister Mohammad Javad Zarif dismissed the British report as “worthless”, according to the semi-official Fars news agency.


A BP spokesman said the oil major’s top priority was the safety and security of its crews and vessels, adding: “While we are not commenting on these events, we thank the Royal Navy for their support.”

BP CEO Bob Dudley, asked about the tensions in the Gulf at an event at London’s Chatham House, said: “We have to be super careful about our ships”.

The world’s most important oil artery links Middle East oil producers with markets in Asia, Europe, North America and beyond. It is just 33 km wide at its narrowest point but the shipping lane is only 3 km wide each way.

Shipping tracker data showed the UK-flagged crude oil tanker Pacific Voyager operated by Mitsui OSK Lines Ltd took a similar route to British Heritage through the Strait of Hormuz this week. Refinitiv data shows four other UK registered tankers currently in the Gulf.

Tensions in the Gulf have escalated as Iran moved from the terms of the 2015 nuclear accord struck with world powers.

The United States withdrew from the pact last year and extended sanctions against Iran, effectively driving Iran from mainstream oil markets and forcing it to find unconventional ways to sell crude, it’s main revenue earner.

That deprived Tehran of the economic benefits Iran was to accrue in return for curbing its nuclear programme. The Islamic Republic says it will only return to full compliance once sanctions are lifted and Washington rejoins the pact.


The long-time foes publicly want to avoid war but the risk of direct confrontation is rising. Last month, Iran shot down a US drone near the Strait of Hormuz.

Trump aborted a retaliatory military strike, saying it could have killed 150 people and signalled he was open to talks with Tehran without preconditions.

The United States hopes to enlist allies in a military coalition to safeguard strategic waters off Iran and Yemen, Marine General Joseph Dunford, chairman of the Joint Chiefs of Staff, said.

European parties to the nuclear accord – Britain, France and Germany – sought to keep the deal alive but Iran said it will take further steps away from the accord unless it is allowed to resume normal oil sales.
