TEHRAN - Iran has formally warned the United States of severe consequences in the event of any military aggression, in a strongly worded letter addressed to the Secretary-General of the United Nations and the President of the UN Security Council. The letter, delivered by Iran’s representative to the United Nations, asserts that all U.S. bases, facilities, and assets in the region would be considered legitimate targets under Iran’s defensive response, while holding Washington fully accountable for any unpredictable outcomes of military action.
