On June 8, 2026, a U.S. Navy missile strike off the coast of Oman struck the Palau‑flagged tanker MT Settebello, killing three Indian sailors aboard. The vessel carried 24 Indian crew members; 21 were rescued by Omani authorities, while the bodies of the missing sailors were recovered the following day.

India’s Ministry of External Affairs (MEA) condemned the incident as a serious breach of commercial shipping safety. On June 12, the ministry summoned U.S. Charge d’Affaires Jason Meeks in New Delhi and lodged a formal protest. The protest was delivered by External Affairs Minister S. Jaishankar, who said he had spoken with U.S. Secretary of State Marco Rubio that evening. In a post on X, Jaishankar wrote: "I reiterated India’s strong protest at the attacks by the US Navy in the Gulf that killed three Indian mariners. Such lethal actions against commercial shipping are not justified."

The U.S. military explained that the tanker was targeted after it allegedly failed to comply with instructions issued by American forces during enforcement of a blockade on Iran‑linked shipping. The blockade, part of a broader U.S. naval campaign, has already disabled three merchant ships in the Gulf of Oman this week.

India’s response has mirrored earlier statements. MEA spokesperson Randhir Jaiswal called for an immediate end to attacks on merchant vessels carrying Indian crew and urged dialogue to restore peace and stability in the region. The government has directed relevant agencies to remain on high alert and to coordinate closely with the Indian Navy, shipping companies, and international maritime authorities.

The incident unfolds amid heightened tensions in the Gulf of Oman. Since mid‑April 2026, the U.S. has been enforcing a naval blockade of Iranian ports following the outbreak of the 2026 Iran war. In retaliation, Iran has blocked the Strait of Hormuz and launched drone and missile attacks on U.S. and allied shipping. The U.S. blockade is described as part of a “dual blockade” that restricts Iranian access to the Gulf while preventing Iranian vessels from transiting the Strait.

India, a major supplier of maritime manpower, has expressed concern that the attacks threaten the safety of its seafarers in one of the world’s busiest shipping corridors. The loss of the three sailors—deck cadet Aditya Sharma, engine fitter Shivanand Chaurasiya and chief engineer Patnala Suresh—has sparked grief across the country.

In the days following the strike, the Indian government has emphasized that attacks on commercial shipping undermine the security and stability of international maritime commerce. The MEA has urged the United States to review its engagement in the Gulf and to ensure that civilian vessels are protected.

The U.S. Department of Defense has not issued a statement specifically addressing the deaths of the Indian sailors, but it has reiterated that its actions are aimed at preventing the transport of Iranian military supplies.

The incident is likely to shape diplomatic discussions between Washington and New Delhi in the coming weeks. India has requested that the U.S. provide assurances that its naval operations will not target vessels carrying Indian crew. The U.S. has not yet responded to the protest.

As the Gulf of Oman remains a flashpoint, the safety of commercial shipping continues to be a key concern for both nations. The Indian government has called for a return to normalcy in maritime traffic and for the protection of its citizens abroad.

The situation remains unresolved. India has not yet received a formal response from the United States, and no new agreements have been announced. The next steps will likely involve diplomatic exchanges and potential negotiations to prevent further incidents.

The incident underscores the broader risks that the 2026 Iran war poses to international shipping and the need for clear rules of engagement in contested waters.
