Tanker strike and rival claims cloud fate of Strait of Hormuz reopening

A missile strike on a UAE state oil tanker has sharpened a standoff over the Strait of Hormuz, where Iran and the United States offer irreconcilable accounts of a deal to reopen the vital energy route.

The Strait of Hormuz has been largely blocked by Iran since 28 February 2026, after the United States and Israel began an air campaign against Iran. Iran says a reopening deal with Oman is near, but its military insists the strait will reopen only if Washington accepts Tehran's conditions.

A vessel belonging to the Abu Dhabi National Oil Company was struck or targeted by a missile while passing through the Strait of Hormuz on Saturday, the UAE state oil firm said. The attack came as Iran and Oman were said to be close to an agreement on reopening the waterway, though the two sides describe very different versions of what that deal would look like. Shipping through the strait has been largely blocked since 28 February 2026, when the United States and Israel began an air campaign against Iran. The Islamic Revolutionary Guard Corps warned vessels away, boarded and attacked merchant ships, and laid sea mines in retaliation. A June Memorandum of Understanding between Tehran and Washington, meant to halt the fighting and reopen the strait within 60 days, collapsed soon after it was signed. What happens next matters far beyond the region. The strait is a key route for global energy supplies, and the competing claims — Iran asserting near-complete control over inbound traffic, Washington insisting it will never accept that — leave the world's most important shipping chokepoint in limbo.

Missile strike on UAE state oil tanker raises stakes in the strait

A vessel belonging to the Abu Dhabi National Oil Company was struck or targeted by a missile while passing through the Strait of Hormuz on a Saturday, according to the UAE state oil firm itself. The company has not publicly confirmed the extent of any damage, whether there were casualties, or who fired the missile, and no other party has claimed responsibility.

The incident fits a wider pattern. Since Iran largely blocked the strait on 28 February 2026, after the United States and Israel began an air campaign against it, the Islamic Revolutionary Guard Corps has warned ships against passage, boarded and attacked merchant vessels, and laid sea mines in retaliation. Whether the ADNOC vessel was hit as part of that same campaign, and whether the strike will affect negotiations over reopening the waterway, remains unclear. Officials in Abu Dhabi have so far offered no further detail beyond the company's account.

Conflicting claims over a deal to reopen the waterway

Tehran has offered a series of optimistic signals about restoring passage through the waterway, but its own statements do not align, and they clash with accounts from others involved. Iran said an agreement with Oman on reopening the strait was nearing completion, and separately said an understanding had been reached on coordinates for a shipping route through it. Neither claim has been confirmed by Muscat in the material available.

Sources familiar with the discussions describe a different picture: the proposed agreement would grant Iran control over inbound shipping traffic, an arrangement that would let ships resume movement while handing Tehran strategic leverage it lacked before the war. Iran's military has set a harder line still, stating the strait would reopen only once the United States accepts Iran's conditions. Whether a deal is close, and on whose terms, remains unresolved, with each side advancing an account the other has not endorsed.

Tehran's toll-and-ban proposal meets flat rejection in Washington

Iran's parliament is weighing a proposal that would bar vessels connected to the United States, Israel, and other countries deemed hostile from using the strait, while imposing a toll on other ships. The Trump administration rejected the plan outright. US officials have repeatedly said they would never accept Iran controlling access to the waterway, a key route for global energy supplies.

The dispute cuts to the heart of the negotiations. According to sources familiar with the discussions, the emerging agreement would permit ships to resume movement through the strait while granting Iran control over inbound traffic — a degree of strategic leverage it lacked before the war. That is precisely what Washington says it will not concede. The parliamentary proposal, if adopted, would formalise the very arrangement US officials have ruled out, leaving the two positions sharply at odds even as talks continue.

A blockade born of war, and a June truce that fell apart

The crisis began on 28 February 2026, when the United States and Israel launched an air campaign against Iran. Tehran responded by largely closing the Strait of Hormuz, the narrow waterway through which a significant share of the world's energy supplies passes. The Islamic Revolutionary Guard Corps warned ships against passage, boarded and attacked merchant vessels, and laid sea mines in retaliation for the strikes.

An attempt to end the standoff came in June, when Iran and the United States signed a Memorandum of Understanding intended to halt the fighting, reopen the strait and produce a deal to end the war within 60 days. The arrangement quickly collapsed, leaving the waterway blocked.

A reopening would restore a critical artery for global oil and gas flows, though under terms that could shift the balance of control in the Gulf.

Frequently asked questions

What happened to the ADNOC vessel in the Strait of Hormuz?

A vessel belonging to the Abu Dhabi National Oil Company was struck or targeted by a missile while passing through the strait on a Saturday, according to the UAE state oil firm.
