The attack on a French cargo ship on May 5 in the Strait of Hormuz was a stark reminder that crossing the waterway remains a risky endeavor with potentially high human costs.

The International Maritime Organization, a part of the United Nations, said the strike injured eight crew members on the San Antonio, a container ship belonging to CMA CGM, a large French shipping company. Iran has attacked ships attempting to cross the strait without its permission.

The strike on the San Antonio occurred before US President Donald Trump paused a large-scale military effort, called Project Freedom, that began this week to protect commercial ships that want to go through the strait.

The US military and CMA CGM disagreed over whether the San Antonio had coordinated with Project Freedom.

A US military official said the French ship did not follow specific Project Freedom guidelines and check-in procedures, adding that when the vessel came under fire, it asked Oman for help, not the United States.

But CMA CGM said in a statement that the ship’s transit through the strait “was carried out as part of” Project Freedom. It added that the voyage was done “in coordination” with the US Naval Cooperation and Guidance for Shipping and “in strict accordance with the required guidelines and procedures”.

The Naval Cooperation and Guidance for Shipping is a US Navy entity that monitors and coordinates with commercial ships.

CMA CGM said that the injured crew members had been evacuated and provided with medical care.
