Two Japanese Oil Tankers Attacked Near Strait of Hormuz

Two oil tankers near the strategic Strait of Hormuz were reportedly attacked on Thursday, an assault that left one ablaze and adrift as sailors were evacuated from both vessels and the U.S. Navy rushed to assist amid heightened tensions between Washington and Tehran.

Japan’s Trade Ministry said the two vessels had “Japan-related cargo” as Prime Minister Shinzo Abe was wrapping up a high-stakes visit in Tehran that sought to ease tensions between Iran and the United States.

Benchmark Brent crude spiked at one point by as much 4% in trading following the reported attack, to over $62 a barrel, highlighting how crucial the area remains to global energy supplies. A third of all oil traded by sea passes through the strait, which is the narrow mouth of the Persian Gulf.

The latest incident comes after the U.S. alleged that Iran used mines to attack four oil tankers off the nearby Emirati port of Fujairah last month. Iran has denied being involved, but it comes as Iranian-backed rebels in Yemen also have launched missile and drone attacks on Saudi Arabia.

Cmdr. Joshua Frey, a 5th Fleet spokesman, said the U.S. Navy was assisting the two vessels that he described as being hit in a “reported attack.” He did not say how the ships were attacked or who was suspected of being behind the assault.

Dryad Global, a maritime intelligence firm, preliminarily identified one of the vessels involved as the MT Front Altair, a Marshall Islands-flagged crude oil tanker. The vessel was “on fire and adrift,” Dryad added. It did not offer a cause for the incident or mention the second ship.

The firm that operates the Front Altair told The Associated Press that an explosion was the cause of the fire onboard. International Tanker Management declined to comment further saying they are still investigating what caused the explosion. Its crew of 23 is safe after being evacuated by the nearby Hyundai Dubai vessel, it said.

The second vessel was identified as the Kokuka Courageous. BSM Ship Management said it sustained hull damage and 21 sailors had been evacuated, with one suffering minor injuries. Iranian state television said 44 sailors from the two tankers have been transferred to an Iranian port in the southern province of Hormozgan.

The timing of Thursday’s reported attack was especially sensitive as Abe’s high-stakes diplomacy mission was underway in Iran. On Wednesday, after talks with Iranian President Hassan Rouhani, Abe warned that any “accidental conflict” that could be sparked amid the heightened U.S.-Iran tensions must be avoided.

His message came just hours after Yemen’s Iranian-backed Houthi rebels attacked a Saudi airport, striking its arrivals hall before dawn and wounding 26 people Wednesday.

Abe met with Iran’s Supreme Leader Ayatollah Ali Khamenei on Thursday, the second and final day of his visit. There were no immediate details about what they discussed.

Meanwhile, in Tokyo, Japan’s Chief Cabinet Secretary Yoshihide Suga, a top government spokesman, told reporters that Abe’s trip was intended to help de-escalate tensions in the Mideast — but not specifically mediate between Tehran and Washington.

His remarks were apparently meant to downplay and lower expectations amid uncertain prospects for Abe’s mission.

Tensions have escalated in the Mideast as Iran appears poised to break the 2015 nuclear deal with world powers, an accord that the Trump administration pulled out of last year.

Iran’s nuclear deal, reached in 2015 by China, Russia, France, Germany, the United Kingdom and the U.S., saw Tehran agree to limit its enrichment of uranium in exchange for the lifting of crippling sanctions. Western powers feared Iran’s atomic program could allow it to build nuclear weapons, although Iran long has insisted its program was for peaceful purposes.

In withdrawing from the deal last year, Trump pointed to the accord not limiting Iran’s ballistic missile program and not addressing what American officials describe as Tehran’s malign influence across the wider Middle East. Those who struck the deal at the time described it as a building block toward further negotiations with Iran, whose Islamic government has had a tense relationship with America since the 1979 takeover of the U.S. Embassy in Tehran and subsequent hostage crisis.

Already, Iran says it quadrupled its production of low-enriched uranium. Meanwhile, U.S. sanctions have cut off opportunities for Iran to trade its excess uranium and heavy water abroad, putting Tehran on course to violate terms of the nuclear deal regardless.
