TEHRAN – Iran has rejected reports that a direct military communication hotline has been established with the United States to manage tensions in the Strait of Hormuz, contradicting claims made by Washington officials.
The denial follows a series of military exchanges between the two nations on June 26 and June 27, raising concerns over the viability of a diplomatic framework intended to secure the world’s most critical oil transit chokepoint, through which an estimated one-fifth of globally traded crude passes each day.
The dispute centers on whether the two powers have agreed to direct military-to-military contact to prevent accidental escalation in the narrow waterway, which has seen increased volatility since a US-Israeli military offensive against Iran began on February 28. At stake is not only operational deconfliction, but how far the two sides are willing to institutionalize any mechanisms to keep commercial shipping moving and avoid a regional war.
Conflict Over Communication Channels
Islamic Revolutionary Guard Corps (IRGC) spokesman Hossein Mohebi denied the existence of the hotline on June 26, specifically targeting assertions that a direct line had been opened to manage the Strait.
“Claims by American officials regarding the establishment of a direct line between Iran and the United States concerning the Strait of Hormuz” are completely false, Mohebi wrote on X. “This has not happened and will not happen … The Strait of Hormuz is Iranian territory and has no connection to the United States.”
The statement directly contradicts assertions made by Vice President JD Vance. Following meetings between officials in Switzerland, Vance informed media on June 22 that a channel for reducing conflict in the Gulf would be established. Vance suggested that a military arrangement had already been reached, stating:
“They [Iran] were like, ‘OK, fine, we’ll send somebody from the IRGC to go hang out in Doha with somebody from CENTCOM,’ and that’s how we’re going to settle a lot of these disputes.”
The IRGC is designated as a foreign terrorist organization by the US government, and US Central Command (CENTCOM) is the unified combatant command responsible for all US military operations in the Middle East, including the US Fifth Fleet’s naval presence in the Gulf.
Adding to the confusion, the Iranian state-run broadcaster Press TV reported on June 26 that a communication line had been established following the Switzerland talks. Press TV stated the goal was to “help prevent incidents that could trigger military escalation” and to implement Article 5 of a Memorandum of Understanding (MoU) signed on June 17.
Article 5 of that agreement specifically addresses the resumption of commercial maritime traffic through the Strait, which has faced prolonged disruptions since February. Diplomats familiar with the talks say the unresolved question is whether this “communication line” is a technical contact arrangement tied to the MoU or a broader, standing military hotline between adversarial commands.
Military Escalation and Maritime Attacks
The diplomatic impasse coincided with a surge in kinetic activity in the Persian Gulf. The current cycle of violence was triggered on June 25 when the Ever Lovely, a Singapore-flagged container ship, was hit by an unknown projectile as it approached the Strait’s eastern entrance.
The vessel had been stranded for over 100 days after unloading cargo in Iraq and was navigating a route recommended by the United Kingdom Maritime Trade Operations (UKMTO) at the time of the attack, underlining how commercial operators have come to rely on military-advised corridors amid contested claims in the waterway.
The sequence of military responses followed:
- June 26: US Central Command targeted military facilities on Iran’s southern coastline, describing the action as a “powerful response to yesterday’s attack on a commercial ship that was transiting the Strait of Hormuz.” US officials framed the strikes as limited and tied to protection of freedom of navigation.
- June 27: Bahrain was targeted by drone strikes in the morning hours, in what regional officials described as retaliation linked to the previous day’s US action.
These events mark the first direct exchange of fire between the US and Iran since the signing of the MoU on June 17 and have effectively turned the still-contested communication channel into a test case for whether the agreement has any restraining power in practice.
Disputes Over Maritime Routing
Tensions are further exacerbated by a disagreement over the legal and physical routing of commercial vessels. Iran has demanded that all ships transiting the Strait of Hormuz use a specific route designated by its armed forces, which runs close to Iranian shores. Tehran has warned that vessels ignoring this route risk being turned back or targeted.
The IRGC has specifically rejected a passage route coordinated between the International Maritime Organization (IMO)-the UN agency responsible for shipping safety-and Oman, claiming that Iran was not consulted on the arrangement. The IMO’s traffic separation schemes are normally recognized internationally and operate alongside the transit passage regime under Part III of the UN Convention on the Law of the Sea, which sets the baseline rules for straits used for international navigation.
Press TV reported that Iran and Oman will instead “determine the future management and maritime services of the Strait of Hormuz, in consultation with other Persian Gulf littoral states and in accordance with international law and the sovereign rights of the littoral states of the Strait of Hormuz.” That framing reflects Tehran’s longstanding view that regional states, rather than extra‑regional navies, should police the waterway.
In response to the targeting of merchant vessels, the UKMTO increased the threat level in the Strait of Hormuz to “substantial” on June 27, signaling to shipowners and insurers that the risk of attack is now considered both credible and likely.
Vice President JD Vance responded to the escalation on June 27 via X, warning that “violence will be met with violence” and stating, “If they have disagreements about how the MoU is being applied, they can pick up the phone.” For the administration, the contested hotline has rapidly become a litmus test of whether quiet crisis-management tools can keep pace with a conflict that is now playing out in one of the world’s most legally sensitive and strategically exposed waterways.
