The U.S. military will begin enforcing a maritime blockade on Iran starting Tuesday, the U.S. Navy-led Joint Maritime Information Center (JMIC) says. In an advisory issued Monday, the JMIC states the blockade covers all Iranian ports, oil terminals and coastal areas. It applies to all vessel traffic, regardless of a ship’s flag. Enforcement is set to begin at 2000 GMT on July 14. Multiple outlets report the same timeline and scope, citing the JMIC notice.
The reporting also indicates the move is communicated through official navigation warnings to mariners. Vessels are advised to monitor relevant navigation notices and contact U.S. forces as needed if they plan to transit to or from Iranian ports or coastal areas. One outlet additionally links the action to recent days of military escalation around the Strait of Hormuz, though the core details across sources focus on the start date, geographic coverage, and that enforcement applies broadly to commercial shipping. The outlets do not provide further specifics on inspection procedures or exemptions.
