The United Nations Security Council convened an emergency session Saturday in New York as American and Iranian diplomats traded direct confrontations before a divided chamber still absorbing the scale of the joint U.S.-Israeli military campaign launched earlier that morning against Iran. The session, called at the request of France, Russia, China, Colombia, and Bahrain, became one of the most charged exchanges the council has witnessed in recent memory — a reflection not only of the military actions underway but of the deep fractures those actions exposed within the international order.

UN Secretary-General António Guterres set the tone from the outset, delivering a warning to all parties that the situation had moved into territory with consequences no single actor could contain.

"The alternative is a potential wider conflict with grave consequences for civilians and regional stability," Guterres told the council.

He characterized the U.S. and Israeli airstrikes as violations of international law, including the UN Charter, while also condemning Iran's retaliatory attacks against Bahrain, Iraq, Jordan, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates for breaching the sovereignty and territorial integrity of those nations. His remarks left no party without criticism, though his call for an "immediate cessation of hostilities" was directed most visibly at Washington and Jerusalem.

The American and Israeli Defense

U.S. Ambassador Mike Waltz did not yield ground. He told the council that Washington's actions were lawful and rooted in a principle the international community had long affirmed.

"Iran cannot have a nuclear weapon," Waltz said. "That principle is not a matter of politics. It's a matter of global security. And to that end, the United States is taking lawful actions."

He dismissed the legitimacy of Iranian grievances at the table, pointing to Tehran's record of suppressing its own citizens. Referencing Iran's crackdowns on protesters, Waltz said the country's presence at the meeting "makes a mockery of this body."

"But where the UN lacks moral clarity, the United States of America will maintain it," he added.

Israeli Ambassador Danny Danon framed the operation in terms of existential necessity, arguing the joint strikes were not acts of aggression but the product of a calculated threat left unaddressed through diplomatic channels.

"We are stopping extremism before it becomes unstoppable," Danon said. "We will ensure that no radical regime armed with nuclear weapons and ballistic missiles can threaten our people or the entire world."

Danon also called out what he described as the hypocrisy of council members who condemned the U.S.-Israeli strikes but made no similar statements about Iran's retaliatory campaign against neighboring Gulf states hosting American forces.

Iran's Countercharges

Iranian Ambassador Amir Saeid Iravani used his time before the council to characterize the strikes as a war crime. He told the chamber that hundreds of Iranian civilians had been killed and wounded in the attacks, singling out the deaths of more than 100 children at Minab School in southern Iran. He called the operation a crime against humanity and accused the council of having failed to act on Tehran's prior warnings about U.S. military buildup in the region.

"The issue before the council is straightforward: whether any member state may, including a permanent member of this council, through the use of force, coercion or aggression, determine the political future or system of another state," Iravani said.

Notably, Iravani did not mention or acknowledge President Trump's statement — made prior to the session — that Supreme Leader Ayatollah Ali Khamenei had been killed in the strikes. Iranian state media later confirmed Khamenei's death.

The sharpest moment of the meeting came in a direct exchange between the two ambassadors near the end of the session. After Waltz addressed Iranian claims that the U.S. had violated international law, Iravani asked to speak once more. "I advise to the representative of the United States to be polite," he said. "It will be better for yourself and the country you represent."

Waltz responded without pause: "This representative sits here, in this body, representing a regime that has killed tens of thousands of its own people, and imprisoned many more, simply for wanting freedom from your entire tyranny."

A Council Divided

The session exposed the depth of disagreement among the Security Council's permanent members. Russia's ambassador Vassily Nebenzia called on the U.S. and Israel to immediately stop what he described as acts of aggression and demanded a return to diplomatic and political settlement processes. China's ambassador Fu Cong expressed serious concern about the escalation and backed Russia's call for dialogue, though his language was somewhat more restrained than Moscow's.

The Arab League's permanent observer, Maged Abdelaziz, raised a pointed question about consistency, noting that Israel, in justifying the strikes on the grounds of preventing Iran from acquiring nuclear weapons, had itself refused to subject its own nuclear facilities to inspection by the UN's nuclear watchdog.

Gulf states offered a different set of grievances. A joint statement read by Bahrain's ambassador on behalf of Saudi Arabia, the United Arab Emirates, Kuwait, Oman, Qatar, Bahrain, Syria, and Jordan directed its sharpest language at Iran's retaliatory missile and drone strikes against their territory.

"We hold the government of Iran fully responsible for these attacks, and we reject any justifications or explanations to justify this hostile behavior or to manipulate rules of international law," the statement read.

The United Kingdom, which holds a rotating council seat and whose presidency of the body ended the same day as the meeting, made clear that British forces had played no role in the strikes. UK Chargé d'Affaires James Kariuki stated as much directly from the chamber floor.

European Leaders and the Call for Negotiations

Outside the council chamber, European governments were navigating a difficult position — neither endorsing the strikes as lawful nor directly confronting Washington. In a joint statement, the leaders of Britain, France, and Germany condemned Iran's retaliatory attacks on regional states in what they called the "strongest terms," while urging all parties to return to negotiations on Tehran's nuclear program. The three nations, all parties to the 2015 nuclear deal from which Trump withdrew the United States in 2018, called for a resumption of talks and said: "Ultimately, the Iranian people must be allowed to determine their future."

French President Emmanuel Macron, who called for the emergency session earlier Saturday, warned separately that the conflict carries "serious consequences for international peace and security" and that "the current escalation is dangerous for everyone. It must stop."

German Chancellor Friedrich Merz was more pointed in his assessment of the Iranian government. He said Berlin shared the relief of many Iranians that what he called the "mullah regime" was "now coming to an end" and stated that Germany, alongside the U.S. and Israel, shared an interest in stopping the regime's nuclear and ballistic missile programs — while acknowledging that international law was "being respected less and less" across the globe.

Guterres, closing the session, offered the starkest framing of what the council had failed to prevent and might still fail to contain. "Military action carries the risk of igniting a chain of events that no one can control in the most volatile region of the world," he said. A return to negotiations, he urged, remained the only viable path forward.

The Security Council adjourned without adopting any resolution, with the U.S. scheduled to assume the body's rotating presidency the following day.
