Iran Sets 5-Day Ultimatum for US to Meet Conditions as Pezeshkian Addresses UNGA

Iran escalated diplomatic tensions with the United States on September 23 at the United Nations General Assembly, with the country's security chief declaring that Tehran would not enter negotiations unless Washington met its conditions within five days. The ultimatum came as internal divisions within Iran also surfaced, with a senior Iranian lawmaker publicly questioning Foreign Minister Araghchi's authority to attend any meeting with US officials.

Iranian President Masoud Pezeshkian used his UNGA address to deliver sharp criticism of Washington, asserting that the US does not respect international law and that Iran must remain strong and powerful to resist what he called its enemies. He also declared that the Strait of Hormuz cannot be used for the passage of weapons intended for use against Iran, a pointed warning with direct implications for regional shipping and US military logistics. A US official walked out of the hall during his speech. Pezeshkian also referred to the assassination of an Iranian leader, saying Iran did not bow but also did not target civilian populations.

The confrontation at the UN unfolded against the backdrop of broader geopolitical uncertainty. Separately, President Trump renewed pledges to end the war in Ukraine, though Reuters reporting noted he has made relatively few concrete commitments to support Ukraine against Russia's invasion, leaving the overall picture largely unchanged.
