Iran’s Permanent Mission to the United Nations has accused the United States of misrepresenting Tehran’s nuclear program and using the Nuclear Non-Proliferation Treaty Review Conference to divert attention from Washington’s own violations, as tensions between the two countries escalated at the UN.In a statement shared on its officialThe statement also criticized international bodies, saying that the UN Security Council, the IAEA Director-General and the Board of Governors not only “failed to condemn these illegal attacks, but most regrettably, they took actions that reversed the roles of victim and attacker.”Iran said the US is portraying its nuclear activities as a threat while ignoring broader disarmament obligations, using the NPT forum to push what it describes as a political narrative.To the United Nations in New York, Iran’s envoy Amir Saeed Erwani warned that lasting stability in the Gulf region requires an end to Iran’s ongoing aggression, as well as guarantees that such actions will not be repeated and that Iran’s sovereignty will be respected.Speaking at the conference, he said Iran supports freedom of navigation in key waterways, including the Strait of Hormuz and the Gulf of Oman, but warned that continued military escalation could undermine regional and global security. He urged the United Nations Security Council to resolve the situation.Ervani alleged that since February 28, the United States and Israel had engaged in a “comprehensive and unjustified aggressive war” against Iran in violation of international law and the United Nations Charter, particularly Article 2(4), adding that these actions had disrupted maritime security.The development comes amid a heated exchange between Washington and Tehran at the NPT review conference in New York, where Iran was chosen as one of the vice-chairs for the month-long meeting.US official Christopher Yeoh criticized Iran’s selection, calling it an “insult” to the treaty. He said it was “undeniable that Iran has long demonstrated its contempt for the NPT’s non-proliferation commitments” and described the move as “shameful and beyond embarrassing for the credibility of this convention.”Reza Najafi, Iran’s ambassador to the International Atomic Energy Agency, dismissed the comments as “baseless and politically motivated.”He said, “It is inexcusable that the United States, as the only state that uses nuclear weapons, and which continues to expand and modernize its nuclear arsenal… wants to position itself as the arbiter of compliance.”The dispute comes as the nuclear issue remains central to the ongoing conflict between Iran, the United States and Israel. US President Donald Trump has repeatedly said Iran cannot be allowed to acquire nuclear weapons, while Tehran says its program is for peaceful purposes.
