It was not immediately clear what befell the Norwegian-owned Front Altair or the Japanese-owned Kokuka Courageous, which both experienced explosions, forcing crews to abandon ship and leave the vessels adrift in waters between Gulf Arab states and Iran.
One source said the blast on the Front Altair, which caught fire and sent a huge plume of smoke into the air, may have been caused by a magnetic mine. The firm that chartered the Kokuka Courageous tanker said it was hit by a suspected torpedo, but a person with knowledge of the matter said torpedoes were not used.
On Thursday night, U.S. Central Command spokesman Bill Urban released a video of what the U.S. military said was an Iranian Revolutionary Guard Corp Gashti Class patrol boat approaching the Kokuka Courageous “and was observed and recorded removing (an) unexploded limpet mine from the M/T Kokuka Courageous.”

The tanker attack will not affect Japanese energy supply, Japanese Industry Minister Hiroshige Seko said, although the ministry issued a warning to Japanese energy companies.
Crude oil prices spiked more than 4% after the attacks near the entrance to the Strait of Hormuz, a crucial shipping artery for Saudi Arabia and other Gulf energy producers. Prices later settled about 2% higher. [O/R] Brent crude LCOc1 was down by 0.4% at $61.06 a barrel in early Asia trading.
The United States, which has accused Iran or its proxies of carrying out a May 12 attack on four tankers off the United Arab Emirates’ coast as well as May 14 drone strikes on two Saudi oil-pumping stations, squarely blamed Iran for Thursday’s attacks.
"It is the assessment of the United States government that the Islamic Republic of Iran is responsible for the attacks that occurred in the Gulf of Oman today," U.S. Secretary of State Mike Pompeo here told reporters.
Pompeo did not provide explicit evidence to back up the U.S. assertion.
“This assessment is based on intelligence, the weapons used, the level of expertise needed to execute the operation, recent similar Iranian attacks on shipping, and the fact that no proxy group operating in the area has the resources and proficiency to act with such a high degree of sophistication,” Pompeo said.
Iran “categorically rejects the U.S. unfounded claim with regard to 13 June oil tanker incidents and condemns it in the strongest possible terms,” the Iranian mission to the United Nations said in a statement on Thursday evening.
It accused the United States and its regional allies, which include Iranian rival Saudi Arabia and the United Arab Emirates, of “warmongering.” Iran called on “the international community to live up to its responsibilities in preventing the reckless and dangerous policies and practices of the U.S. and its regional allies in heightening the tensions in the region.”

U.S. and European security officials as well as regional analysts cautioned against jumping to conclusions about who carried out the attacks, leaving open the possibility that Iranian proxies, or someone else entirely, might have been responsible.
In London, British Foreign Secretary Jeremy Hunt said the UK was taking the matter “extremely seriously” and that if Iran was involved, “it is a deeply unwise escalation which poses a real danger to the prospects of peace and stability in the region.”
