A US military aircraft fired precision munitions on a tanker in the Gulf of Oman earlier this week, disabling the vessel’s engine room after it allegedly attempted to transport Iranian oil in violation of an American naval blockade, according to statements from the US military and regional maritime authorities.
The incident, confirmed Wednesday by the United States Central Command (CENTCOM), marks a significant escalation in the enforcement of Washington’s maritime restrictions in one of the world’s most strategically sensitive waterways. The targeted vessel, identified as the Palau-flagged oil tanker M/T Settebello, reportedly suffered engine room damage after a US warplane struck it with precision-guided munitions following what CENTCOM described as repeated non-compliance with instructions from American forces.
The strike occurred in the waters off Oman in the broader Gulf of Oman, a critical maritime corridor linking the Arabian Sea to the narrower approaches of the Strait of Hormuz, through which a significant portion of global oil shipments traditionally pass.
In a post on X, United States Central Command said the aircraft “fired precision munitions into the ship’s engine room after the crew repeatedly failed to comply with directions from American forces.”
The command added that since the initiation of the blockade on April 13, CENTCOM forces have disabled eight non-compliant vessels, redirected 134 ships that complied with instructions, and permitted 42 vessels carrying humanitarian supplies to pass through unaffected.
Military officials did not immediately provide detailed evidence of the alleged oil transport from Iran, but US authorities have consistently argued that maritime interdiction operations are designed to prevent sanctioned Iranian exports from reaching global markets during the ongoing regional conflict.
The strike underscores a broader shift toward direct kinetic enforcement at sea, where drones, naval aviation assets, and surface vessels have increasingly been deployed to monitor and interdict shipping activity.
Shortly after the strike, maritime monitoring organizations reported that the tanker suffered a fire in its engine room and issued a distress call indicating that it had been struck by a missile while operating near Sohar, Oman.
The United Kingdom Maritime Trade Operations agency said the vessel reported one casualty and two crew members missing as emergency response teams moved toward the scene.
“Local authorities have reported a tanker has experienced a fire in their engine room and are on the scene assisting with the evacuation of the crew,” the agency said.
Separately, maritime security firm Vanguard Tech reported that the Settebello had transmitted a distress signal indicating its engine room had been hit by a missile, resulting in onboard fire and structural damage that left the vessel immobilized.
The incident has triggered diplomatic concern in South Asia after the government of India confirmed that several of its nationals were onboard the tanker.
India’s foreign ministry said 24 Indian crew members were present on the vessel at the time of the attack. In an official statement, New Delhi confirmed that 21 crew members had been rescued, while three remain missing.
“Our Embassy in Oman is closely monitoring the situation and proactively coordinating with the Omani authorities in the ongoing Search and Rescue operation,” the statement said.
India strongly condemned the attack on the commercial vessel, warning that repeated incidents involving merchant shipping in the region pose a grave threat to civilian lives and global maritime trade. The ministry further called for immediate de-escalation of tensions and urged all parties to return to negotiations to restore stability.
In a separate development, an Indian official told AFP that the foreign ministry had “summoned (US) charge d’affaires, lodged a strong protest” over the strike, signaling diplomatic strain between New Delhi and Washington over the escalation.
The Gulf region has seen mounting disruption to maritime traffic since the outbreak of the wider Middle East conflict earlier this year. Analysts say the effective closure of the Strait of Hormuz has created severe bottlenecks for global energy markets, with insurers warning of heightened risk premiums for vessels transiting nearby waters.
Shipping through the region has reportedly been “almost completely blocked” since the onset of hostilities, with only limited humanitarian and compliant commercial traffic continuing under military escort or coordination mechanisms.
The crisis escalated following US-Israeli strikes on Iran in late February, which triggered retaliatory actions and a fragile ceasefire arrangement that has repeatedly come under strain.
Despite ceasefire efforts that began in April, diplomatic negotiations aimed at reopening the Strait of Hormuz have stalled, with neither side agreeing on enforcement mechanisms or security guarantees for commercial shipping.
Tensions intensified further following comments by US President Donald Trump, who warned that US forces would continue military operations against Iran in response to recent escalations.
Speaking from the Oval Office, Trump said the United States had already conducted strikes in retaliation for the downing of a US Apache helicopter earlier in the week, an incident that further destabilized the fragile ceasefire environment.
“We hit them hard yesterday. We’re going to hit them again hard today,” Trump told reporters, adding that Iranian negotiators had failed to engage in good faith discussions.
He accused Tehran of delaying peace talks despite what he described as a fully negotiated framework agreement.
“We were really close to a deal, but they keep tapping us along, they keep playing us for suckers,” Trump said.
In earlier remarks on social media, Trump characterized Iran as the “Bully of the Middle East” and suggested that the country would “have to pay the price” for prolonging negotiations.
He also praised the maritime blockade of Iranian shipping, describing it as “the most successful” in history and a “steel wall” that had effectively cut off Iranian commercial maritime activity while still permitting other nations’ oil exports.
The US military confirmed it carried out strikes earlier in the week targeting Iranian assets after a US military helicopter was shot down. The aircraft’s two crew members were rescued following the incident, according to US officials.
In response, Iranian forces claimed they had launched attacks on American bases located in Jordan and Bahrain, further widening the geographic scope of the confrontation.
Military analysts warn that the exchange of strikes risks broadening the conflict beyond maritime interdiction operations, potentially drawing in additional regional actors and complicating already fragile diplomatic efforts.
The Gulf of Oman and the adjacent Strait of Hormuz remain among the most strategically important maritime chokepoints globally. Roughly one-fifth of global oil shipments historically transit these waters, making them a focal point for both military planning and international energy security concerns.
Any sustained disruption to navigation in this region has immediate consequences for global oil prices, shipping insurance costs, and supply chain stability. The current blockade regime has already forced several shipping companies to reroute vessels around the southern tip of Africa, significantly increasing transit times and costs.
The latest incident involving the Settebello has added fresh diplomatic strain between Washington and New Delhi, even as broader international concern grows over the safety of civilian shipping in the region.
India’s call for de-escalation reflects wider global unease about the potential for maritime incidents to spiral into a broader regional war. At the same time, US officials continue to insist that enforcement actions are necessary to prevent sanctioned Iranian oil exports from financing military operations.
