Iran seizes oil tanker in Gulf of Oman after alleged collision amid regional tension

Marshall Islands-flagged, Turkey-managed ship had just come from Kuwait and was heading to Texas, US Navy says, noting that Tehran’s actions are ‘contrary to international law’

DUBAI, United Arab Emirates — Iran’s navy seized a Marshall Islands-flagged oil tanker in the Gulf of Oman on Thursday amid wider tensions over Tehran’s nuclear program, the latest-such capture in a waterway crucial for global energy supplies.

Iran’s army said two Iranian crew members were missing and several others injured after a collision in the Gulf involving the oil tanker that was later seized by its forces.

The US Navy’s Mideast-based 5th Fleet identified the vessel as the Advantage Sweet. Satellite tracking data for the vessel from showed it in the Gulf of Oman just north of Oman’s capital, Muscat, on Thursday afternoon. It had just come from Kuwait and listed its destination as Houston, Texas.

The Advantage Sweet issued a distress call at 1:15 p.m. while in international waters as Iran seized the vessel, the Navy said.

“Iran’s actions are contrary to international law and disruptive to regional security and stability,” the 5th Fleet said in a statement. “Iran should immediately release the oil tanker.”

The US Navy initially said Iran’s paramilitary Revolutionary Guard seized the vessel, but an American naval aircraft later confirmed that Iran’s navy captured the ship, 5th Fleet spokesman Cmdr. Timothy Hawkins told The Associated Press.

Iran’s state-run IRNA news agency confirmed the seizure, saying it had come after an “unknown ship collided with an Iranian vessel last night in the Persian Gulf, causing several Iranian crew members to go missing and get injured.” It did not identify the other ship involved in the alleged collision.

“The unknown vessel, while acting in violation of international regulations to help the vessel and the injured, attempted to escape from the Persian Gulf,” it added.

“In this operation, the Binder destroyer of the navy of the army, by court order, seized the violator ship that was fleeing with the flag of the Marshall Islands and directed it to the coastal waters of the Islamic Republic of Iran,” the statement read.

The Advantage Sweet had been in the Persian Gulf on Wednesday, but its track showed no usual behavior as it transited through the Strait of Hormuz, through which a fifth of all oil traded passes. Iran has made allegations in other seizures that later fell apart as it became clear Tehran was trying to leverage the capture as a chip to negotiate with foreign nations.

Iran’s “harassing activity within the Persian Gulf and Gulf of Oman is commensurate with an established pattern of behavior that has seen Iran target vessels as a result of ongoing disputes,” maritime security firm Dryad Global said.

The 5th Fleet said the Iranian seizure was at least the fifth commercial vessel taken by Tehran in the last two years.

“Iran’s continued harassment of vessels and interference with navigational rights in regional waters are a threat to maritime security and the global economy,” it added.

The vessel’s manager, a Turkish firm, did not respond to requests for comment. Its listed owner appeared to be a Chinese company.

Thursday’s seizure by Iran was the latest in a string of hijackings and explosions to roil the region.

The incidents began after then-US president Donald Trump unilaterally withdrew the United States from Iran’s nuclear deal with world powers, which saw Tehran drastically limit its enrichment of uranium in exchange for the lifting of economic sanctions.

Also, the US Navy has blamed Iran for a series of limpet mine attacks on vessels that damaged tankers in 2019, as well as for a fatal drone attack on an Israeli-linked oil tanker that killed two European crew members in 2021.

Tehran denies carrying out the attacks, but a wider shadow war between Iran and the West has played out in the region’s volatile waters. Iranian tanker seizures have been a part of it since 2019. The last major seizure came when Iran took two Greek tankers in May and held them until November.

Meanwhile, talks over Iran’s tattered nuclear deal have been stalled for a year. Since the deal’s collapse, Iran runs advanced centrifuges and has a rapidly growing stockpile of enriched uranium. The head of the International Atomic Energy Agency has warned Iran has enriched enough up to 60-percent purity — a short technical step from weapons-grade levels of 90%. That would be sufficient for Iran to make several nuclear weapons if it chooses to do so.
