Iran notified the UN and the International Maritime Organization that "hostile vessels" may pass through the Strait of Hormuz if they coordinate with Iranian authorities. This announcement comes as the conflict significantly disrupts approximately one-fifth of global oil and liquefied natural gas shipments through this waterway.

Iran's Ministry of Foreign Affairs sent the notification to the UN Security Council and Secretary-General Antonio Guterres on Sunday, and the message was then distributed to 176 member states of the International Maritime Organization.

Iran specified that "hostile vessels, including those belonging to or associated with other states, may exercise the right of innocent passage through the Strait of Hormuz in coordination with Iranian authorities. The condition is that they do not participate in or support aggression against Iran and fully respect the announced security regulations."

The document emphasizes that Iran has taken "necessary and proportional measures to prevent aggressors and their supporters from exploiting the Strait of Hormuz for hostile operations."

Notably, the vessels, equipment and property of the US or Israel - as well as other parties involved in the conflict - do not qualify for safe or innocent passage.
