Oman has presented Iran with a plan backed by Gulf states to manage the Strait of Hormuz, including collecting voluntary fees for using it, a Gulf source and a Western diplomat have told Reuters. The plan could serve as a basis to end the disruption to trade through the strait caused by the US-Israeli war on Iran. Iran effectively shut the strait to ships other than its own after the United States and Israel attacked on 28 February. Iran has said it wants to manage the strait alongside Oman, which controls the opposite shore, and charge service fees to ships that use it. The Gulf source said that as of Monday evening there had been no formal response from Iran to the proposal.
