President Donald Trump has accused Tehran of breaching a newly brokered ceasefire in the Strait of Hormuz, calling an Iranian drone attack on a commercial ship a “foolish violation” of the agreement signed just last week. The ceasefire was intended to guarantee safe navigation through the strategic waterway and open the door for negotiations on Iran’s nuclear program.
In a post on Truth Social, Trump confirmed the United States had intercepted three of four one-way attack drones launched by Iran, but acknowledged one struck the upper deck of a cargo vessel. The British military also reported on Thursday that a ship was hit by a projectile off the coast of Oman, shortly after several tankers had used a U.N.-backed transit route.
The incident marks the first major test of the fragile ceasefire, which was signed amid rising tensions over Iran’s nuclear ambitions and repeated harassment of commercial shipping. Trump did not explicitly say whether the attack would end negotiations with Iran, but the accusation signals a hardening stance.
Iran asserts control over the Strait
Iranian Deputy Foreign Minister Kazem Gharibabadi responded swiftly, issuing a statement on X that underscored Tehran’s dominance over the Strait of Hormuz. “Safe passage through the Strait of Hormuz, with ambiguous arrangements, parallel routes, or decision-making outside of Iran’s considerations as the coastal state, cannot be guaranteed,” he wrote.
That warning effectively challenges the legitimacy of the ceasefire, which was negotiated without direct Iranian participation. Tehran has long insisted that any security arrangement in the Strait must be coordinated with its military and political leadership.
The attack and the subsequent exchange come as Trump prepares to address the Faith & Freedom Coalition, a gathering that will likely see him defend his handling of the Iran situation amid broader midterm concerns. Meanwhile, his administration faces multiple pressures, including a standoff with Congress over housing policy and demands from Senate Republicans on election legislation and defense funding.
The Strait of Hormuz, through which about 20% of the world’s oil passes, remains a flashpoint for U.S.-Iran confrontation. The Trump administration has steadily increased naval patrols in the region, and the downing of three drones suggests the U.S. military is operating under rules of engagement that allow for immediate self-defense.
Iran’s defiance, combined with the ceasefire violation, threatens to derail any diplomatic progress. The British military’s confirmation of the attack adds international pressure, though it remains unclear whether European allies will back Trump’s accusation or call for an independent investigation.
The incident also raises questions about the viability of the U.N.-backed transit corridor, which was designed to bypass Iranian interference. For now, commercial shipping in the region faces heightened risk, and insurers are likely to raise premiums for vessels transiting the Strait.
