Iran Blocks Strait of Hormuz Opening, Citing Ceasefire Violations by US and Israel

Tehran's chief negotiator declares passage through critical waterway impossible amid mounting tensions and vessel seizures

Iran's lead representative in negotiations with the United States has declared it "impossible" to reopen the Strait of Hormuz, attributing the decision to what he characterizes as systematic violations of the ceasefire agreement by American and Israeli forces.

Diplomatic Stalemate Deepens

Mohammad Bagher Ghalibaf, Iran's chief negotiator, posted his statement on X on Wednesday, listing specific grievances against both nations. He accused the US of maintaining a naval blockade of Iranian ports that he claimed effectively held the global economy "hostage," while simultaneously condemning Israeli "warmongering" across multiple fronts.

Despite this hardline stance, Iran's President Masoud Pezeshkian signaled openness to resumed dialogue. However, he framed three conditions as prerequisites for meaningful negotiations: an end to ceasefire breaches, lifting of economic blockades, and cessation of threats against Iran.

Negotiations Postponed as Tensions Escalate

Anticipated peace talks scheduled for this week in Pakistan have not yet commenced. Vice-President JD Vance, designated to lead the American delegation, remains in the United States rather than traveling to Pakistan.

On Tuesday evening, President Donald Trump announced an extension of the US-Iran ceasefire, which had been set to expire on Wednesday. White House Press Secretary Karoline Leavitt subsequently clarified that this extension carries no fixed endpoint and remains indefinite. She expressed Trump's satisfaction with the ongoing naval blockade and noted that "Iran is in a very weak position."

When pressed on a potential end date for hostilities, Leavitt stated that timing depends entirely on Trump's assessment of American interests and national security.

Maritime Incidents Complicate Situation

The diplomatic impasse coincides with escalating activity in the strategically vital waterway. On Wednesday morning, Iran announced the capture of two cargo vessels in the Strait of Hormuz for what it termed "inspection" purposes. This announcement followed reports of attacks on three separate merchant ships traversing the passage.

The Iranian Revolutionary Guard Corps Navy released statements claiming the seized vessels—MSC Francesca and Epaminondas—were operating without proper authorization and had committed "repeated violations" of maritime protocols. The statement alleged the ships attempted to leave the strait covertly and interfered with navigation systems. Iranian media outlets affiliated with the IRGC subsequently broadcast footage showing commandos boarding both vessels.

The third targeted vessel, Euphoria, a UAE-registered container ship, suffered attack approximately eight nautical miles west of Iran according to maritime security assessments. Tracking data indicates the ship subsequently resumed southbound transit and anchored near the United Arab Emirates port of Khor Fakkan.

Greece's Foreign Minister Giorgos Gerapetritis confirmed that Epaminondas, a Greek-flagged cargo ship, sustained attack, though he stopped short of formally verifying Iran's seizure claim when speaking to CNN.

Command Changes at Pentagon

Separately, the US Defense Department announced Wednesday that Secretary of the Navy John Phelan would depart from his position "effective immediately," with no explanation provided. Navy Undersecretary Hung Cao assumes the role in an acting capacity. The departure follows recent pressure on Army Chief of Staff Randy George by Defense Secretary Pete Hegseth.

Strategic Calculations

The White House's decision to establish no deadline for either resumed negotiations or potential military action appears deliberate. This approach grants the Trump administration considerable latitude to allow economic pressure through the blockade to accumulate against Iran while simultaneously avoiding a return to large-scale military operations that could destabilize global markets.

Leavitt suggested the indefinite timeline aims to encourage pragmatic Iranian officials to formulate peace proposals without interference from hardline factions. Notably, she stated the administration does not classify Iran's seizure of the two merchant vessels as a ceasefire violation, emphasizing that neither ship belonged to the United States or Israel.
