Vessel movements through the Strait of Hormuz stopped less than 24 hours after Iran announced its reopening, as armed confrontations forced ships to retreat, reported London's Lloyd's List.

Iranian gunboats opened fire on at least three vessels, ending a brief resumption of traffic. Two ships were struck, including the 15,254-TEU CMA CGM Everglade, which sustained container damage after being hit by a projectile. No fire was reported, and the crew remained safe. CMA CGM has yet to confirm the incident.

The French liner had prepared three boxships - CMA CGM Everglade, 2,592-TEU CMA CGM Manaus, and 3,500-TEU CMA CGM Diamond - to exit the strait following the reopening. Data from Seaexplorer showed the vessels remained in the Persian Gulf at the time of reporting.

The situation escalated further on Sunday, 19 April, when the US Navy seized an Iranian-flagged container ship in the Arabian Sea near the strait. US Central Command stated that warnings were issued for six hours before US Marines boarded and took control after the crew ignored repeated instructions.

Iran responded with threats of retaliation, warning that the seizure jeopardized renewed ceasefire negotiations.
