MUSCAT – A drone attack on a cargo vessel in the Strait of Hormuz has forced the United Nations to suspend a critical evacuation mission, signaling a precarious breakdown in the fragile ceasefire governing the Middle East.
The incident, which occurred 14 kilometers off the coast of Oman, has reignited tensions between Washington and Tehran, threatening to destabilize a maritime chokepoint through which approximately one-fifth of the world’s total oil and gas exports flow.
The attack underscores the volatility of a region still reeling from a conflict launched by the United States and Israel on February 28. While a ceasefire officially took effect on April 8, the persistence of “gray zone” warfare-characterized by drone strikes and maritime harassment-continues to jeopardize global energy security and the safety of thousands of merchant seafarers.
US President Donald Trump condemned the operation, describing it as a “foolish” violation of the existing peace agreement.
“One of the Drones solidly hit the upper deck of a large and very expensive Cargo Carrying Ship” while three others were shot down, Trump posted on his Truth Social platform.
“Obviously, this is a foolish violation of our Ceasefire Agreement,”
he added.
The United Kingdom Maritime Trade Operations (UKMTO) confirmed on Thursday that a vessel was “hit on the starboard side by an unknown projectile, causing damage to the bridge.” No casualties were reported in the strike.
The immediate operational fallout fell upon the International Maritime Organization (IMO). Secretary General Arsenio Dominguez announced the suspension of efforts to evacuate roughly 600 ships and 11,000 sailors currently trapped in the Gulf.
The UN maritime body reported that since Tuesday, 115 vessels and 2,500 seafarers had already been successfully evacuated. Mr. Dominguez stated that the decision to pause the mission followed “consultations with some countries, particularly in the region,” adding that the pause was intended to allow coastal states, flag states and navies to reassess risk and deconflict routes through the strait.
The Strait of Hormuz is governed in part by the international regime on freedom of navigation and transit passage laid out in the UN Convention on the Law of the Sea, but Iran and its neighbors continue to contest how those rules apply in practice to foreign warships, commercial tankers and newly created emergency corridors.
Contested Corridors and Maritime Transit
The attack has highlighted a growing dispute over the legal and physical navigation of the Strait. In an attempt to bypass Iranian interference and maintain what the IMO describes as “safe and efficient shipping on clean oceans,” the IMO and Oman established a new transit corridor hugging the Omani coastline for use by evacuation convoys and commercial vessels.
The Islamic Revolutionary Guard Corps (IRGC) has vehemently rejected this arrangement, claiming the corridor was established without Tehran’s consultation and asserting Iran’s right to regulate movements in what it regards as its territorial waters and security perimeter.
“The only authorised transit routes through the Strait of Hormuz are those designated by the Islamic Republic of Iran,” the IRGC stated, issuing a warning to vessels attempting to use the non-approved passage.
Diplomats say the competing corridor claims risk hardening into a broader legal dispute over who decides routing through one of the world’s most sensitive energy arteries, and whose security doctrine prevails when UN-coordinated missions intersect with national red lines.
Despite the risks, shipping data suggests a tentative return to the waterway, though traffic remains well below peacetime levels. According to tracking platform Kpler:
- Thursday: 42 commodity vessels crossed the strait (10 entering, 32 exiting).
- Friday: 29 commodity vessels crossed by afternoon (10 entering, 19 leaving).
- Route distribution: On Thursday, roughly half of the 42 vessels utilized the southern Omani passageway, with the remainder following more traditional central and northern tracks.
- Peacetime baseline: The strait typically sees approximately 125 transits per day.
The danger of the Omani route was underscored by a Singapore-flagged container ship, which reported being struck while utilizing the passageway on Thursday. Maritime security officials say the incident will likely prompt insurers, flag states and shipowners to reassess war-risk premiums, crewing decisions and route planning for voyages transiting the Gulf.
Market Volatility and the ‘Ketchup-Bottle’ Effect
The geopolitical instability has sent immediate ripples through global commodity markets. The price of Brent North Sea crude, the international benchmark, dropped more than five per cent on Friday. Analysts attribute this dip to market optimism that the strait is reopening to commercial traffic and that evacuation convoys, once resumed, could normalise export flows.
However, maritime experts warn that this price correction is premature and does not reflect a genuine return to stability or a settled security framework for the waterway.
Richard Meade, editor-in-chief of the shipping journal Lloyd’s List, argues that the current increase in traffic is a logistical anomaly rather than a sign of peace.
“The sudden surge in shipping through the Strait of Hormuz has been greeted in some quarters as evidence that the region is snapping back to normal. It isn’t,” Meade said. “What we are witnessing is a ceasefire‑driven release of pent‑up demand — a ketchup‑bottle burst of tonnage.”
Meade cautioned that the Strait “may be busier, but it is not safer,” noting that normality cannot be forecasted until the terms of a post-ceasefire regime are fully established and respected, including clear rules of engagement for drones, naval patrols and commercial convoys.
Energy traders and shipping executives are now watching three parallel tracks: talks between the United States and Iran over a longer-term security understanding; regional discussions over acceptable transit corridors; and the IMO’s ability to restart its evacuation operation without exposing crews to escalating drone and missile threats. Until those pieces align, officials concede, the Gulf will remain open for business only in a narrow, heavily hedged sense.
Negotiations for a long-term settlement between the United States and Iran remain ongoing, while the IMO continues to monitor the safety of the remaining trapped crews in the Gulf and to liaise with coastal states and naval coalitions over when conditions will allow the suspended rescue convoys to resume.
