In a letter for UN Secretary-General António Guterres and President of the UN Security Council Michael G. Waltz on March 26, Saeed Iravani raised alarm over alleged plans by the US and Israel to assassinate senior Iranian officials, asserting that such actions constitute serious breaches of international law and threaten global peace and security.

The text of the letter is as follows:

In the Name of God, the Most Compassionate, the Most Merciful

Excellency,

Upon instructions from my Government, and further to my previous communications regarding the acts of aggression, war crimes and acts of terrorism being committed by the United States and the Israeli regime against the sovereignty and territorial integrity of the Islamic Republic of Iran since 28 February 2026, I write to draw the urgent attention of Your Excellency and the members of the Security Council to reports in the media indicating that the United States and the Israeli regime have identified and designated senior Iranian officials including the Speaker of the Islamic Consultative Assembly, Mr. Mohammad Bagher Ghalibaf, and the Minister for Foreign Affairs, Mr. Seyed Abbas Araghchi-as targets for assassination, with any suspension of such plans described as temporary.

The reports indicate the existence of an operational framework contemplating the assassination of the highest-ranking political officials of the Islamic Republic of Iran. Such a policy has, in practice, already been pursued, systematically and in particular since the outset of the acts of aggression against Iran on 28 February 2026, including through the assassination of the Supreme Leader of the Islamic Revolution and several senior political officials. Such a policy constitutes clear evidence of a serious breach of peremptory norms of international law. The conditional nature of the purported "suspension" further underscores that the threat remains real, deliberate and ongoing.

Such threats, emanating from criminal mindsets who have openly dismissed the "rules of engagement" as "stupid", are deeply alarming. In collaboration with terrorists in charge of Tel Aviv, they have so far, in clear acts of State terrorism and deliberately, bombed and murdered hundreds of students, bombed hospitals, and destroyed cultural heritage sites, among other atrocities. The promotion of so-called "terror lists" must therefore be understood as yet another manifestation of the same acts of terrorism that have begun a criminal war against Iran, which has thus far resulted in the deaths of more than three thousand civilians.

The premeditated policy of assassinating high-ranking officials of a sovereign Member State of the United Nations constitutes a clear violation of the Charter of the United Nations. Any such unlawful and cowardly act constitutes not only an act of terrorism but also a flagrant violation of international human rights law, including the right to life, and a serious breach of international humanitarian law.

It must also be emphasized that officials of the rank of Minister for Foreign Affairs enjoy full immunity ratione personae under customary international law, as repeatedly affirmed by the International Court of Justice. Any attempt on their lives would violate their personal inviolability and undermine the foundations of peaceful international relations.

The Islamic Republic of Iran categorically condemns any policy aimed at normalizing the assassination of senior State officials. Such a destructive and malicious policy and practice amount to State-sponsored terrorism, set a dangerous precedent and represent a serious escalation that threatens international peace and security. Full responsibility squarely lies with the United States and the Israeli regime for engaging in such internationally wrongful acts.

Given the gravity and ramifications of these breaches implicating fundamental principles of international law, the foundations of the international community and the raison d'être of the United Nations-the Islamic Republic of Iran calls upon the Security Council to:

• Unequivocally condemn any threat or act of assassination against State officials and leaders as a clear violation of international law, including international humanitarian law and international human rights law;
• Hold accountable those responsible for planning, authorizing, supporting and committing such acts of terrorism; and
• Force the United States and the Israeli regime to uphold their binding obligations under the Charter of the United Nations and international law, and to cease all grave violations and unlawful actions against the Islamic Republic of Iran.

If such grave threats and violations are left unaddressed or unanswered, this would set an exceedingly dangerous precedent, eroding the foundations of international law and exposing all States to similar unlawful and destabilizing practices.

I should be grateful if you would have the present letter circulated as an official document of the Security Council and of the General Assembly under agenda item 84, entitled "The rule of law at the national and international levels".

Please accept, Excellency, the assurances of my highest consideration.
