IMO pauses Hormuz evacuations

What's happened

The UN's International Maritime Organization has paused its evacuation of around 600 stranded ships and 11,000 seafarers after a vessel was struck off Oman's coast on Thursday. The attack, which multiple maritime sources say likely involved a drone or unknown projectile, has prompted fresh warnings from Iran and halted the IMO operation while safety guarantees are rechecked.

What's behind the headline?

What the pause means

• The IMO has paused the evacuation because it has received reports of an attack on a vessel that transited the strait. The agency is repeating safety checks before it resumes individual transits.

Who holds leverage now

• Iran is enforcing its own routes through the Strait and the new Persian Gulf Strait Authority has warned that transits outside Tehran-approved corridors "will not be covered by the guarantee of safe passage." That stance gives Iran direct control over which ships feel safe to move.

Immediate consequences

• The pause will delay planned phased departures of ships and prolong hardship for thousands of seafarers who have been stranded. It will keep commercial insurance and operational caution high, slowing traffic recovery.

Strategic trajectory

• The pause will increase pressure on diplomatic channels. The evacuation effort requires cooperation between the IMO, coastal states and military actors; if those actors cannot guarantee protection, the operation will remain suspended.

Forecast

• Shipping will continue to rise slowly where vessels accept coastal escorts or clearances, but full restoration to prewar levels will not happen while strike risks and contestation over routing persist. The pause will force faster diplomatic clarification: either Iran will accept coordinated passages or maritime actors will seek stronger international escorts to guarantee movement.

How we got here

The IMO has launched a phased operation, backed by Oman, Iran and the United States, to move ships out of the Persian Gulf through two temporary routes after months of closure during the US-Israel war with Iran. Traffic has risen since a recent US–Iran memorandum but remains below prewar levels.

Our analysis

The reporting converges on the same sequence but emphasises different details. The International Maritime Organization's stance appears in Reuters and the New York Times Business: Reuters quotes IMO Secretary-General Arsenio Dominguez saying the agency "has started contacting the ships to start the evacuation" and that safety guarantees had been secured. The New York Times Business reported the IMO had "secured the necessary safety guarantees" and cited figures of 600 ships and 11,000 crew. AP and the Guardian focus on the attack that prompted the pause: AP quoted a U.S. official saying the vessel was hit by an Iranian drone and named the merchant ship Ever Lovely; AP also published the IMO pause and noted Iran's Persian Gulf Strait Authority wrote that transit outside Iran's routes "will not be covered by the guarantee of safe passage." CNBC, Axios and Al Jazeera report operational detail and the immediate security response: CNBC and Axios cite IMO Secretary-General Dominguez saying the evacuation will be paused "in order to reconfirm" safety conditions, while Al Jazeera and the UKMTO describe the strike location and a likely drone origin. Taken together, the sources show agreement on the pause and its cause, with variation on attribution of the strike: AP and some maritime security outlets point to an IRGC drone, while other outlets report an "unknown projectile" or that attribution is under investigation. Readers can consult Reuters and the New York Times Business for IMO statements, AP for the attribution claim and Al Jazeera and the Guardian for on-the-water detail and Iran's official warnings.
