UN suspends Hormuz evacuation mission after reported ship attack The UN's International Maritime Organisation (IMO) has suspended its programme to escort ships and seafarers through the Strait of Hormuz after a cargo vessel reported a suspected attack near Oman, raising fresh concerns over maritime security. UK Maritime Trade Operations (UKMTO) said the ship reported being attacked hours after Tehran warned vessels against using routes it had not approved. "I have decided to temporarily suspend its implementation in order to ensure that the necessary safety guarantees are still available for the ships on our evacuation list, and for all ships in the area," IMO Secretary-General Arsenio Dominguez said.
