The United States accused Iran of carrying out the attacks on two oil tankers in the Gulf of Oman on Thursday that drove up oil prices.
However, Tehran vociferously denied the allegations.
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.”
Japanese Industry Minister Hiroshige Seko said that the tanker attack will not affect Japanese energy supply. However, the ministry has 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.
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.
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.
