I am writing to you with utmost urgency and deep alarm regarding a brazen and unlawful act of aggression perpetrated by the Israeli regime against the Islamic Republic of Iran. In a reckless and deliberate escalation that flagrantly violates the Charter of the United Nations and the most fundamental norms of international law, Israel has launched a coordinated series of military assaults targeting several Iranian cities and peaceful nuclear facilities, senior military officials, scientists and civilians.

Among the targets was the Natanz nuclear facility, one of Iran’s principal nuclear sites, which operates under the full safeguards and monitoring of the International Atomic Energy Agency (IAEA). This reckless attack has not only endangered Iranian civilian lives, but also posed an alarming threat to regional and international peace and security by risking a radiological disaster. Any deliberate military targeting of nuclear facilities under international safeguards constitutes a grave violation of international law. This dangerous assault further undermines the global non-proliferation regime and the integrity of the IAEA mission.

Simultaneously, a number of targeted assassinations of senior Iranian military officials and scientists have been carried out in the capital, Tehran. These deliberate and premeditated acts constitute clear instances of state terrorism. The responsibility for these heinous crimes has been publicly and arrogantly claimed by the regime’s Prime Minister himself, constituting an open admission of responsibility.

These outrageous actions represent not only a grave violation of Iran’s sovereignty and territorial integrity as a sovereign State Member of the United Nations, but also constitute acts of aggression and war crimes under international law and international humanitarian law, including the Geneva Conventions. Most critically, these heinous attacks constitute a blatant violation of Article 2 (4) of the Charter of the United Nations, which unequivocally prohibits the threat or use of force against the territorial integrity or political independence of any State.

These coordinated acts mark yet another episode in Israel’s pattern of unlawful and destabilizing conduct in the region, which poses a serious threat to international peace and security. Israel, the most terrorist regime in the world, has now crossed every red line, and the international community must not allow these crimes to go unpunished. The Security Council and the Secretary-General must condemn this aggression and act immediately and unambiguously. This is not merely a military attack against one nation – it is a direct assault on the principles that underpin the international legal order. Failure to respond will only embolden the aggressor, reward impunity and invite further chaos in an already fragile region.

The Islamic Republic of Iran reaffirms its inherent right to self-defence as enshrined in Article 51 of the Charter and will respond decisively and proportionately to these unlawful and cowardly acts. The Islamic Republic of Iran will act with full resolve to protect its sovereignty, its people and its national security. This right is non negotiable. Israel will come to deeply regret this reckless aggression and the grave strategic miscalculation it has made.

Given the seriousness of this unlawful aggression and its implications for international peace and security, I call for the immediate and urgent convening of an emergency meeting of the Security Council. The Council must fulfil its responsibilities under the Charter, strongly condemn this act of aggression and take urgent and concrete measures to hold the Israeli regime fully accountable for its crimes.

I request that the present letter be circulated as a document of the Security Council and brought to the attention of all Member States.
