Qatar Presented Iran a New Proposal to End the War. Tehran Called it ‘Unacceptable.’

Qatari mediators have presented Iran with the latest proposal to end the war with the U.S., but Tehran dismissed it as chances of renewed escalations appear to be climbing again.

A senior Iranian official told Reuters on Wednesday that the offer passed on by Doha only included "unacceptable ideas" that did not amount to an offer.

The official went on to note that Tehran's nuclear policy remains unchanged and won't show any flexibility there.

In this context, the International Atomic Energy Agency's (IAEA) Board of Governors referred Iran's nuclear file to the Security Council for the first time in two decades.

IAEA Director General Rafael Grossi said at Tuesday's UN Security Council meeting that Tehran continues refusing to give international inspectors access to its damaged nuclear facilities, hit last year during the war with Israel and the U.S.

Grossi went on to say that the IAEA will continue working with Tehran to clarify unresolved matters and that any path toward solving disputes must include inspections from the watchdog.

The development comes after Fars news agency, closely linked with the Iranian Revolutionary Guard Corps (IRGC), claimed that Supreme Leader Mojtaba Khamenei is urging for faster technological progress, including in the nuclear area.

Khamenei claimed that the "experience of the two recent wars has demonstrated to everyone that this new scientific surge must be deep and rapid," the outlet added.

The reported remarks come days after an Iranian lawmaker appeared to suggest that Khamenei could be more open to pursuing a nuclear weapon than his father, Ali Khamenei.

"From Mojtaba Khamenei's conduct, my understanding is that his fatwa will be different," Ahmad Naderi said, in reference to the doctrine from Ali Khamenei claiming Iran would not seek a nuclear weapon due to religious motives.

Elsewhere, another report detailed that the United States has warned Gulf allies to prepare for a return to full-fledged hostilities in Iran

The campaign is set to take place after the midterm elections next week, The Wall Street Journal noted, and of a short and intense nature.

The escalation intends to force Tehran back to the negotiating table as the conflict remains at a stalemate. Trump has repeatedly hinted at potential attacks after the midterms.
