The security situation in the Strait of Hormuz has taken another dangerous turn after the United States launched fresh military strikes against Iranian targets in response to recent attacks on commercial vessels, prompting the International Maritime Organization (IMO) to issue one of its strongest warnings yet to the global shipping industry.

The IMO is urging shipowners, operators and flag states to avoid sending vessels through the vital waterway if they cannot guarantee the safety of their crews, highlighting growing concerns that the region could face another prolonged disruption.
The latest escalation follows U.S. military operations targeting more than 80 sites across Iran. According to U.S. Central Command (CENTCOM), the strikes hit air defense systems, command centers, coastal radar installations, anti-ship missile capabilities and dozens of fast attack boats operated by Iran’s Islamic Revolutionary Guard Corps (IRGC) around the Strait of Hormuz.
Washington said the military action was carried out after three commercial vessels came under attack while transiting the strait. The affected ships included the Marshall Islands-flagged tanker Al Rekayyat, the Saudi-flagged Wedyan, and the Liberia-flagged Cyprus Prosperity.
CENTCOM described the attacks as a serious breach of the existing ceasefire arrangement and reaffirmed that U.S. forces remain ready to respond to any further threats against international shipping.
U.S. Tightens Sanctions on Iran
Alongside the military response, the Trump administration has also reversed its temporary sanctions relief on Iranian oil exports.
The U.S. Treasury announced that the waiver previously allowing limited Iranian energy transactions has been withdrawn. Companies are being given a short wind-down period to complete existing business, but no new purchases or shipments of Iranian crude, petroleum products or petrochemicals will be allowed after the deadline.
The move signals a significant deterioration in relations between Washington and Tehran just weeks after both sides agreed to a memorandum aimed at reducing tensions and reopening the world’s most important oil transit route.
President Donald Trump indicated the agreement may now be effectively finished.
Speaking before the NATO summit, Trump said he no longer believed negotiations with Iran were worthwhile following the latest attacks on commercial vessels.
IMO Issues Strongest Safety Appeal
The renewed violence prompted IMO Secretary-General Arsenio Dominguez to issue a direct appeal to the shipping industry, condemning the attacks and urging companies to place crew safety above commercial operations.
He said the latest incidents have once again exposed innocent seafarers to unacceptable risks and stressed that no maritime worker should face life-threatening conditions simply for carrying out their duties.
Dominguez called on flag administrations, shipping companies and relevant authorities to avoid routing vessels through the Strait of Hormuz whenever crew safety cannot be guaranteed.
He also urged all governments involved in the crisis to immediately reduce tensions and facilitate the safe departure of thousands of seafarers who remain stranded aboard vessels inside the Persian Gulf.
Industry estimates suggest nearly 6,000 seafarers are still unable to leave the region safely because of the ongoing security concerns.
The IMO’s latest advisory marks a significant shift from the cautious optimism seen after last month’s ceasefire, when shipping companies had begun cautiously restoring operations through designated transit corridors.
Iran Rejects U.S. Accusations
Iran has denied violating the agreement and instead accused Washington of escalating the conflict.
Parliament Speaker Mohammad Bagher Ghalibaf said the United States had repeatedly breached the memorandum through renewed military strikes, tougher oil sanctions, interference in Hormuz shipping operations, attacks inside southern Iran and continued support for Israeli military actions.
He insisted Iran would not yield to external pressure and rejected accusations that Tehran was responsible for undermining the agreement.
Shipping Industry Faces Fresh Uncertainty
The renewed exchange of military action has once again raised serious concerns over the security of one of the world’s busiest maritime chokepoints.
The Strait of Hormuz handles a significant share of global oil and liquefied natural gas exports, making any disruption a major concern for energy markets, global supply chains and international shipping.
With fresh attacks, military retaliation and diplomatic tensions continuing to escalate, carriers, insurers and cargo owners are once again being forced to reassess operational risks while awaiting greater clarity on whether commercial traffic through Hormuz can remain safe in the weeks ahead.
