UN Halts Emergency Shipping Route After Cargo Ship Hit in the Persian Gulf

The International Maritime Organization suspended its evacuation operation in the Strait of Hormuz on Thursday. A cargo ship had been struck by a projectile while using a UN-backed corridor that was supposed to be safe for stranded vessels and crew.

This corridor was a carefully arranged agreement. The IMO—the United Nations agency that oversees international shipping—had negotiated it with relevant parties to help commercial ships escape the strait safely. Those ships had been effectively trapped due to military tensions in the Persian Gulf. When the cargo ship was hit, the entire evacuation plan was put on pause.

So far, no one has claimed responsibility for the strike. The UN has not publicly blamed anyone. As of June 25, the identity of the targeted ship and the amount of damage have not been confirmed by independent reporting.

Why This Matters

The Strait of Hormuz is one of the world's most important shipping channels. About 20 percent of the world's oil passes through this 21-nautical-mile-wide waterway between Iran and Oman. If shipping there is disrupted for any length of time, it immediately affects energy prices and supply chains far beyond the Gulf itself. The IMO's evacuation corridor had been a rare moment of cooperation in an increasingly tense environment—Reuters reported on June 23 that the plan was actively working before Thursday's strike.

Now dozens of commercial ships and their crews are stuck again in a dangerous situation. Seafarers stranded in or near the strait face real hazards: ongoing military activity, problems with their contracts, and the inability to get fresh supplies or change out crew members. For the IMO, this evacuation operation had been one of its most challenging assignments in recent years.

What Happens Next

The big unknown: was the projectile deliberately aimed at the evacuation corridor, or was it an accident?

If it was deliberate, it sends a stark signal. It would mean at least one side is willing to attack even a nominally protected humanitarian passage. That would make any future evacuation corridor much harder to negotiate. If it was an accident, there might be room to redesign the plan with better safeguards and clearer communication protocols. The IMO has not yet said when it will reassess the situation.

The pressure on the strait has been building for weeks. U.S. military activity against Iran and the resulting security risks have left shipping companies with few safe options. Insurance companies have already raised the war-risk fees for ships passing through the Gulf, and many owners had been counting on the IMO corridor to get their vessels out safely. That exit is now closed, at least for now.

For the companies that own ships and the governments that flag them, the immediate question is whether the IMO will try to restart the corridor with new rules—perhaps with more advance notice, different sailing times, or more countries involved in guaranteeing safety—or whether the risks have become too high to make a resumed operation realistic in the near term.
