Iran says no tangible progress has been made in U.S. talks and warns of a crushing response to renewed American or Israeli attacks

Iran said Tuesday that indirect diplomatic exchanges with the United States have produced no tangible breakthrough, warning that any renewed military attack on Iranian territory would face a “crushing response” even as Tehran keeps diplomatic channels open.

Foreign Ministry spokesman Esmaeil Baqaei said Iran continued to exchange messages with Washington through regional mediators but had seen no new developments that would bring the two sides closer to an agreement.

“Past experiences leave no room for optimism about the United States’ seriousness regarding diplomacy,” Baqaei said, according to Iranian state media.

He emphasized that Iran remained prepared to defend itself and deliver a crushing response to any aggression, while continuing to pursue diplomatic opportunities that could safeguard its national security and legitimate interests.

The remarks followed several days of consultations involving Qatari mediators, who have been working to bridge differences between Tehran and Washington over a proposed agreement to end the conflict and restore maritime security in the Strait of Hormuz.

Iranian negotiators left Doha on Sunday, but an official briefed on the discussions told Reuters their departure was not caused by difficulties in the talks. A draft proposal continued to circulate, and further consultations remained possible.

Tehran insists that any agreement must address its demands, including an end to the U.S. naval blockade of Iranian ports and the removal of economic restrictions. Iran has proposed accelerating implementation of its existing seven-step framework to just two days, without abandoning its conditions.

The diplomatic uncertainty comes amid renewed military tensions. U.S. forces recently struck an Iranian air-defense facility on Qeshm Island, while President Donald Trump has warned that further strikes remain possible if negotiations fail.

Qatar says both countries are still examining proposals, but a senior Iranian official told Reuters that their positions remain far apart, accusing Washington of making excessive demands.
