Mohammad Baqer Qalibaf, the Speaker of the Iranian Islamic Consultative Assembly (Majles) and head of the Iranian negotiating delegation, has hit back at threats made by US President Donald Trump, declaring that Tehran "places no weight on American threats."

In his response, Qalibaf questioned the American stance, asking: "Do they not consider that if their threats were to yield any result, they would not have reached the state of helplessness they find themselves in today?"

Reiterating a warning to Washington, Qalibaf stated that it would be best for the Americans "to be cautious in their statements," adding that the Iranian armed forces "are prepared to respond to them in a different manner." He further remarked: "No matter how much they talk, we are the ones who execute on the ground and we are the ones who act."

This comes after the Tasnim News Agency cited a source close to the Iranian negotiating team confirming that the delegation had walked out of the venue in protest against Trump’s recent hostile remarks. The Iranian delegation formally conveyed its protest to the American side and is currently evaluating its options to respond to the threats. According to a report by Press TV, Tehran considers that "based on Clause 2 of the understanding, any threat constitutes a flagrant violation of the text."

In this context, the bureau director of Al Mayadeen in Geneva reported that Trump’s remarks "cast a shadow over the atmosphere of the negotiations, making them more complicated." Meanwhile, Iranian state television quoted a member of the Iranian delegation who warned: "If an end to the war in Lebanon is not achieved, the negotiations will not continue."

President Trump had previously claimed that the United States "might seize control of the Strait of Hormuz if it fails to reach an agreement with Iran." Directly addressing the Tehran negotiating team in Switzerland, Trump warned, "If you close it , you will no longer have a country," and threatened an attack on Iran.

These developments unfolded after Tehran closed the strategic Strait of Hormuz in retaliation for US violations of the Memorandum of Understanding, alongside ongoing aggression against southern Lebanon.

Notably, Trump's threats emerged just as quadrilateral negotiations—aimed at following up on the implementation of obligations under the Islamabad Memorandum of Understanding—had commenced earlier today at the Bürgenstock Hotel in Switzerland. This round followed various diplomatic meetings in Geneva, which included bilateral and trilateral formats at the Bürgenstock resort to prepare for and pave the way toward the launch of the first official formal session of negotiations between the United States and Iran.
