JUST IN: Iran Reimposes Control Over Strait of Hormuz and Fires on Ships, Citing Ongoing U.S. Blockade

Iran has once again tightened its grip on the Strait of Hormuz, reversing a brief reopening of the critical waterway and firing on merchant vessels attempting to pass. The move comes in direct response to the continued U.S. naval blockade of Iranian ports, which Tehran describes as “piracy” and a violation of understandings reached during recent ceasefire efforts.

First Vice President Mohammad Reza Aref reinforced Iran’s position, stating that control of the strait “is in our hands” and that the country will secure its rights “either at the negotiating table or on the battlefield.”

What Happened: Brief Reopening Followed by Renewed Closure and Gunfire

According to multiple reports, Iran had briefly allowed limited commercial traffic through the strait after a reported 50-day period of restrictions. At least eight vessels reportedly crossed during this short window. However, Tehran quickly reversed course, reimposing strict military controls and warning that passage requires explicit Iranian authorization.

Iranian Revolutionary Guard Corps (IRGC) gunboats then opened fire on ships attempting to transit, including incidents involving a tanker and a container vessel. Some ships were hit by projectiles, while others reversed course. Maritime security sources, including the UK Maritime Trade Operations (UKMTO), confirmed the attacks and the resulting disruptions.

The IRGC Navy broadcast warnings that any vessel trying to cross without permission “will be met with a severe response … and will be destroyed.”

Iranian Officials’ Statements

• First Vice President Mohammad Reza Aref: “The management of the Strait of Hormuz is with Iran… We will establish our rights either at the negotiating table or on the battlefield.”
• Deputy Foreign Minister Saeed Khatibzadeh: Expressed frustration with U.S. President Donald Trump, saying he “talks too much,” sends contradictory messages, and creates confusion. Khatibzadeh noted that the American side “tweets a lot” and that it is sometimes hard to understand what Washington wants.

Iranian military spokesmen described the re-closure as a necessary response to the U.S. continuing its blockade despite earlier signals of de-escalation.

U.S. Blockade and Broader Context

The U.S. has maintained its naval blockade of Iranian ports, turning back multiple vessels and preparing to board and seize Iran-linked “dark fleet” tankers in international waters. U.S. officials, including Chairman of the Joint Chiefs Gen. Dan Caine, have signaled a firm commitment to disrupting Iran’s oil exports and shadow fleet operations.

This tit-for-tat escalation occurs as:

• U.S.-Iran nuclear talks remain stalled over major gaps, particularly on uranium enrichment.
• Fragile ceasefires hold in other areas, such as the 10-day Israel-Lebanon truce.
• Recent incidents include gunfire on merchant vessels, including Indian-flagged ships, prompting diplomatic protests from India.

The Strait of Hormuz remains one of the world’s most vital energy arteries. Renewed restrictions and threats of destruction against transiting ships risk higher oil prices, increased shipping insurance costs, and potential broader naval confrontations.

Potential Global Impact

Any prolonged disruption in the Strait of Hormuz could have severe consequences for global energy markets, affecting importers in Asia, Europe, and beyond. Analysts warn that repeated incidents could deter commercial shipping and escalate tensions between Iran and the U.S. and its allies.
