Iran (IMNA) - In the letter, Iran's Ambassador and Permanent Representative to the United Nations, Amir Saeid Iravani, said the United States had failed to uphold its commitments under the memorandum shortly after it was signed.
"Almost immediately after the signing of the Memorandum, and continuing to the present day, the United States has not only failed to honor its commitments but has actively and systematically undermined the very foundations of the Memorandum," Iravani wrote in the letter addressed to UN Secretary-General António Guterres and the president of the Security Council.
The letter denounces what Iran describes as continued US violations of the Islamabad MoU and calls attention to Washington's conduct before the United Nations.
The text reads as follows:
The full text of the letter is as follows:
Excellencies,
Upon instructions from my Government, I wish to inform Your Excellency and the members of the Security Council that, following the unprovoked acts of aggression against the Islamic Republic of Iran by the United States and the Israeli regime, in flagrant violation of Article 2(4) of the Charter of the United Nations and the peremptory norm of prohibiting aggression — acts which commenced on 28 February 2026 and have included numerous war crimes and crimes against humanity, the Islamabad Memorandum of Understanding was signed by the Presidents of the Islamic Republic of Iran and the United States on 17 June 2026, in 14 paragraphs. The Memorandum was from the very outset conceived not on the basis of trust — for no such trust existed — but on a clear structure of “commitment for commitment,” designed to provide a genuine opportunity for diplomacy and to establish a framework for the peaceful resolution of outstanding issues through mutual and reciprocal obligations.
Almost immediately after the signing of the Memorandum, and continuing to the present day, the United States has not only failed to honour its commitments but has actively and systematically undermined the very foundations of the Memorandum. Its actions—including repeated military attacks against Iran's sovereignty and territorial integrity, the unlawful revocation of the license for the sale of Iranian oil, the promotion of a parallel maritime route in the Strait of Hormuz in contravention of the agreed arrangements, and its continued support for Israeli aggression against Lebanon constitute fundamental and unequivocal breaches of its commitments. This systematic pattern of breach is most clearly demonstrated by the United States' conduct regarding paragraph 5 of the Memorandum, which explicitly affirms the Islamic Republic of Iran's responsibility for determining the arrangements for the safe passage of vessels through the Strait of Hormuz. In clear contravention of this provision, the United States has unilaterally challenged this arrangement and has sought to impose a parallel maritime route. These unilateral actions, combined with continued acts of aggression against Iran, constitute a material breach of the Memorandum and a fundamental breach of the agreed framework.
These deliberate, calculated, and sustained actions constitute a grave threat to international peace and security and further demonstrate the United States' complete disregard for its international legal obligations. These violations are not merely abstract statistics on a page, but they have a devastating human cost. These casualties add to the already heavy toll of lives lost throughout the war, as a direct consequence of the United States' unlawful use of force against the Islamic Republic of Iran.
In light of the gravity of this situation, the Islamic Republic of Iran recalls the responsibilities entrusted to the Security Council of the United Nations under its Charter, particularly in situations involving acts of aggression, breaches of the peace, and threats to international peace and security. Iran urgently calls upon the United Nations to discharge, without delay, its Charter-mandated responsibilities by taking immediate, effective, and decisive measures to compel the United States to cease its ongoing unlawful acts of aggression, prevent any further escalation, and ensure the full accountability of the United States for its acts of aggression, grave violations of international law, and the serious crimes resulting therefrom.
Regrettably, the Security Council's failure to take timely, effective, and decisive action in response to these manifest violations of the Charter of the United Nations has emboldened the United States to continue and further escalate its unlawful use of force against the Islamic Republic of Iran, thereby undermining the authority of the Council and jeopardizing international peace and security.
The Islamic Republic of Iran reiterates that the United States bears full and unequivocal responsibility for all consequences arising from its unlawful use of force and for the grave threat that its unlawful actions pose to international peace and security. The Islamic Republic of Iran will resolutely safeguard its national interests, protect its sovereignty, and defend its territorial integrity against any aggression.

These strikes constitute a further violation of the commitment to terminate military operations and to respect the sovereignty and territorial integrity of Iran.

13 July 2026 — Violation of Paragraphs 1 and 4: The President of the United States posted on Truth Social, announcing the “reinstating [of] the IRANIAN BLOCKADE,” thereby declaring the reimposition of a blockade against Iran.
It should be emphasized that each of these violation reports was formally conveyed to the mediators, with a request for their facilitation to secure the immediate cessation of the violations and to obtain firm assurances of non-repetition. However, the United States not only failed to honour its commitments but continued to escalate its unlawful actions with complete disregard for its commitments under the Memorandum.
I should be grateful if you would have the present letter circulated as an official document of the Security Council.
Please accept, Excellencies, the assurances of my highest consideration.
