A new element in the Hormuz picture: the IMO has been running an evacuation operation for vessels in the region, and it has now been halted.

Infomarine, relaying an IMO statement, reports that the organisation began evacuating vessels from the region this week in cooperation with member states and industry, and that Secretary-General Arsenio Dominguez has decided to temporarily pause implementation "in order to reconfirm that the necessary safety guarantees continue to be in place for the ships on our evacuation list and all those in the region" [1].

The trigger was an attack. Dominguez said he had been informed of an attack "today" in the Gulf of Oman on a vessel which had passed through the Strait of Hormuz. He stressed that this vessel did not transit under the IMO's evacuation framework [1]. The statement as reproduced does not name the ship, identify who attacked it, or say whether anyone was hurt, and the available text is cut off mid-sentence, so those details cannot be confirmed from this source.

Two things follow. First, the pause is a signal about confidence: an organisation that had judged evacuation safe enough to start now says it needs to re-verify the guarantees underpinning it. Second, the IMO's own framing separates ships moving under its framework from those moving independently — the attacked vessel was in the latter category, which says nothing reassuring about the corridor generally.

This sits alongside the other threads already covered: the UK and French mine-hunting forces reported to be positioned for a limited de-mining operation in Omani waters, itself said to have been set back by fresh attacks on vessels, and the unresolved question of how much traffic is actually moving through the strait [1].

Caveats: the pause is attributed to the IMO Secretary-General directly, but the underlying attack is reported at second hand, with no vessel name, attacker or casualty information in the fetched text. Treat the attack as reported, not confirmed.
