On April 13, Iran submitted an official document to the Legal Committee of the International Maritime Organization (IMO), systematically detailing for the first time the damage inflicted on its maritime sector by recent conflicts:

39 merchant ships were sunk, 110 fishing vessels were damaged, and 20 seafarers lost their lives; even medical ships and search-and-rescue vessels were not spared.

The document also noted that port navigation systems have been jammed, vessels at anchor have sustained damage, and maritime traffic services have been disrupted—should this infrastructure be paralyzed, the safety of navigation across the entire region would be in grave danger.

Iran stated that the current deterioration of the situation in the Persian Gulf stems directly from external attacks.

Iran subsequently announced that vessels from countries involved in the attacks would be barred from transiting the Strait of Hormuz; other nations wishing to pass through must coordinate in advance with the relevant Iranian authorities.

Although Iran has indicated it will cooperate with Oman to establish a framework for safe passage in the future, uncertainty continues to mount for the time being.
