US Navy says mine fragments suggest Iran behind Gulf tanker attack

FUJAIRAH: The United States sought on Wednesday to bolster its case for isolating Iran over its nuclear and regional activities by displaying limpet mine fragments it said came from a damaged oil tanker and saying the ordnance looked Iranian in origin.

Iran has denied involvement in explosive strikes on two tankers in the Gulf of Oman last week and four tankers off the United Arab Emirates on May 12, both near the Strait of Hormuz, a major conduit for global oil supplies.

But the incidents have fuelled tensions that flared with the US pullout last year from world powers’ 2015 nuclear accord with Iran, followed by fresh US sanctions to stifle Tehran’s vital oil trade, and a retaliatory Iranian threat this week to resume uranium enrichment in breach of the deal.

France and Germany said on Wednesday they would crank up efforts to halt any spiral towards conflict with Iran, but that time was running out and the risk of war could not be ruled out.

Iran’s signal of preparedness to stockpile enriched uranium beyond the deal’s limit, and refine uranium to a fissile purity higher than deemed necessary for civilian uses, prompted US President Donald Trump to warn on Tuesday he was ready to take military action to stop Tehran developing a nuclear bomb.

The Islamic Republic denies having any such intentions.

But Trump also left open whether he would support the use of force to protect Gulf oil supplies Washington fears might be put in jeopardy by Iran in the brewing confrontation.

“We want to unify our efforts so that there is a de-escalation process that starts,” French Foreign Minister Jean-Yves Le Drian told reporters in Paris.

“There is still time and we hope all the actors show more calm. There is still time, but only a little time.”

Iran, where hardline foes of detente with the West have been strengthened by Trump’s pressure campaign, said on Wednesday it would give European powers no more time beyond July 8 to save the nuclear deal by shielding its economy from US sanctions.

President Hassan Rouhani said Iran’s actions were the “minimum” Tehran could undertake one year after the Trump administration withdrew from the deal, but that its steps were reversible “if they return to their commitments”.

Iran’s Foreign Ministry said later that senior diplomats from Iran, France, Britain, Germany, Russia and China – the remaining signatories to the nuclear deal – would hold the next quarterly meeting of the accord’s oversight commission in Vienna, where the UN nuclear watchdog is based, on June 28.

Underscoring regional jitters, Kuwait and Iraq called for wisdom and reason in dealing with the latest developments in order to defuse tension and forestall clashes, Kuwait’s state news agency KUNA reported.


In the United Arab Emirates port of Fujairah on Wednesday, the US Navy exhibited pieces of limpet mines and a magnet it said its personnel extracted from one of two oil tankers attacked in the Gulf of Oman last week.

The US military earlier released images it said showed Iranian Revolutionary Guards removing an unexploded mine from Japanese-owned tanker Kokuka Courageous, which was hit by blasts along with Norwegian-owned Front Altair tanker on June 13.

“The limpet mine that was used in the attack is distinguishable and also strikingly bearing a resemblance to Iranian mines that have already been publicly displayed in Iranian military parades,” Sean Kido, commanding officer of an explosive ordnance dive and salvage task group in the US Naval Forces Central Command (NAVCENT), told reporters.

Small fragments said to have been removed from the Kokuka Courageous were on display alongside a magnet purportedly left by the Revolutionary Guard squad allegedly captured on video.

The Japanese company that owns the Kokuka Courageous had said its ship was damaged by two “flying objects”, but NAVCENT dismissed this account.

“The damage at the blast hole is consistent with a limpet mine attack, it is not consistent with an external flying object striking the ship,” Kido said, adding that nail holes visible in the hull indicated how the mine was attached to the ship’s hull.

The location of the mine above the ship’s waterline indicated the intention was not to sink the vessel, he said.

Two Western security sources told Reuters this week the attacks seemed calibrated to inflict only limited damage and avoid injury to show that Iran could sow chaos if it wanted to, possibly to persuade Washington and other foes to back off rather than trigger conflict.

Kido also said NAVCENT had collected biometric information including fingerprints from the ship’s hull that would help in crafting a criminal case against the assailants.


In another incident likely to fan tensions, a rocket crashed onto a site in southern Iraq used by foreign oil companies on Wednesday, including US energy giant ExxonMobil, wounding three people.

There was no immediate claim of responsibility for the attack near the southern Iraqi city of Basra – the fourth time in a week rockets have landed near US installations. There were no casualties or major damage in the earlier incidents.

An Iraqi security source said it appeared that Iran-backed groups in southern Iraq were behind Wednesday’s Basra incident.

Iranian officials have made no comment about the attack but have strongly denied all other allegations that Tehran has targeted energy tankers and facilities in the region.

Although the United States and Saudi Arabia have pointed fingers at Iran for all the tanker attacks, several European nations have said more evidence is needed.

“The dynamics of the two attacks are not clear, and the video that the US said demonstrated Iran’s role was also not clear,” a Western diplomat in the Gulf told Reuters.
