Iran’s Khatam al-Anbiya central military command said the vessel was en route from China when it came under attack, warning that Iranian forces would respond. A spokesperson described the incident as “armed piracy” and said retaliation would follow.U.S. President Donald Trump said earlier that a U.S.

Navy destroyer intercepted the ship, identified as the MV Touska, after it failed to comply with repeated warnings while attempting to breach a U.S.-imposed maritime blockade on Iranian ports.Trump said the vessel was disabled after the USS Spruance fired on its engine room and that U.S. Marines had taken control of the ship.

He added that the Touska was subject to U.S. Treasury sanctions due to a history of alleged illegal activity.The U.S. Central Command said the destroyer issued warnings over a six-hour period before using force to stop the vessel, marking the first such interception since the blockade began last week.

It added that U.S. forces have turned back at least 25 commercial vessels attempting to navigate the restricted waters.The confrontation comes amid heightened instability in the Strait of Hormuz, a critical route for global oil and gas shipments, which has remained largely closed since the outbreak of the U.S.-Israel conflict with Iran seven weeks ago.

Iran briefly reopened the strait on Friday following a ceasefire in Lebanon but shut it again within 24 hours, citing continued U.S. naval restrictions. The uncertainty has disrupted maritime traffic, with vessel tracking data showing tankers reversing course in recent days.Energy analysts warned that the renewed tensions could drive volatility in oil markets after a brief easing late last week.

Amrita Sen, founder of Energy Aspects, said developments over the weekend underscored the fragility of the situation and the risk of further escalation.

The incident adds pressure on diplomatic efforts to stabilize the region, with markets and governments closely monitoring the standoff for signs of either de-escalation or further conflict.

Among the ships that passed through the waterway were five vessels that had last loaded cargoes from Iran, including oil products and metals, while three liquefied petroleum gas carriers were bound for destinations including China and India.A Panama-flagged tanker carrying LPG from the United Arab Emirates was headed to Indonesia, while two other tankers loaded with refined products from Bahrain were en route to Mozambique and Thailand, respectively, according to the data.

Shipping activity also included a Liberian-flagged tanker transporting around 500,000 barrels of UAE naphtha to Ulsan in South Korea, and a very large crude carrier hauling roughly 2 million barrels of Saudi oil toward Taiwan. Another vessel carrying about 780,000 barrels of Das crude from the UAE was bound for Sri Lanka.

Additional cargoes moving through the strait included fertiliser shipments from Qatar to the UAE and petroleum coke exports from Saudi Arabia to Italy.

The uptick in vessel movements comes after weeks of disruption linked to heightened geopolitical tensions in the Gulf, which had sharply curtailed tanker traffic through one of the world’s most vital energy transit routes.

The statement, issued by Iran’s foreign ministry and shared with IMO member states and non-governmental organizations, said vessels that do not “participate in or support acts of aggression” against Iran would be permitted safe passage through the strategic waterway, subject to adherence to safety and security regulations.

However, it specified that vessels, equipment, and assets belonging to what it described as “aggressor parties” including the United States and Israel would not qualify for what it termed “innocent or non-hostile passage.

”Iran said responsibility for any disruption or escalation in the Strait of Hormuz lay with Washington and Tel Aviv, accusing them of waging an “unlawful and destabilising war” that has heightened risks to international shipping and regional stability.

The statement reflects Tehran’s position as tensions remain elevated following the outbreak of war triggered by U.S.-Israeli strikes on Iran on February 28.

The Strait of Hormuz, one of the world’s most critical maritime chokepoints, has been effectively closed since the escalation, contributing to sharp increases in global oil and gas prices.

Iran’s conditional reopening for select vessels introduces limited operational clarity for commercial shipping, though the exclusion of U.S. and Israeli-linked assets underscores the continuing strategic and geopolitical risks in the region.
