Iran has informed the UN Security Council and the International Maritime Organization that "non-hostile vessels" may pass through the Strait of Hormuz provided they coordinate with Iranian authorities, according to a document reviewed by Reuters on Tuesday.

The U.S.-Israeli war against Iran has virtually halted the shipment of approximately one-fifth of the world's oil and liquefied natural gas supplies through the strait, causing major disruptions to oil deliveries.

The note from Iran's Foreign Ministry was sent to the 15 members of the Security Council and UN Secretary-General António Guterres on Sunday, and was subsequently circulated on Tuesday to the 176 members of the London-based UN agency responsible for regulating the safety of international shipping and preventing marine pollution.

"Non-hostile vessels, including those belonging to or associated with other states, may — provided they do not participate in or support acts of aggression against Iran and fully comply with the stated security and safety regulations — make use of safe passage through the Strait of Hormuz in coordination with the competent Iranian authorities," the document states.

It notes that Iran has "taken necessary and proportionate measures to prevent aggressors and their supporters from using the Strait of Hormuz to conduct hostile operations against it."

The document further states that vessels, equipment, and any assets belonging to the United States or Israel "as well as other participants in the aggression, shall not be entitled to claim peaceful or non-hostile passage."
