International Maritime Organisation (IMO) Secretary-General Arsenio Dominguez says that the group’s evacuation plan for vessels stranded in the Strait of Hormuz, which launched earlier this week, has been suspended, Al Jazeera reports.

Earlier, the United Kingdom Maritime Trade Operations reported that a vessel was hit near Oman’s coastal waterways in the Strait of Hormuz.

“I have been informed of an attack today in the Gulf of Oman on a vessel which passed through the Strait of Hormuz. This vessel did not transit under [the] IMO’s evacuation framework,” he says in a statement.

“Following the launch of the IMO’s evacuation plan, through which several vessels have already been successfully evacuated, I have decided to temporarily pause its 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.”
