Members of Iran’s delegation left the negotiating venue with representatives of the United States after threats voiced by US President Donald Trump, Iran’s Tasnim news agency reported.

Later, Iranian Parliament Speaker Mohammad Bagher Ghalibaf said Washington should choose its words more carefully, warning that the Iranian army was ready to deliver a serious response. In a post on social media, he argued that American threats had proved ineffective and said Tehran was not paying attention to them.

According to Tasnim, the remarks by the White House’s occupant contradict the first clause of the memorandum of understanding between the United States and Iran. That clause requires both sides to refrain from threatening each other.

Al Mayadeen reported that Iran demanded an apology from Trump as a condition for continuing the talks. Iranian negotiators are also now insisting not only on an end to hostilities in Lebanon, but also on the withdrawal of Israeli forces from South Lebanon.

At the same time, Al Hadath said contacts between representatives of Tehran and Washington are continuing in Switzerland in an unofficial format through mediators.

The talks began in Switzerland on June 21. The first round ended in the evening, after which the participants paused for consultations.

Trump had earlier said he had contacted the Iranian negotiators and sharply demanded that they not close the Strait of Hormuz. His message also contained threats. Fox News journalist Trey Yingst said the US president warned Iran that if it closed the strait, it would lose the country and its representatives would not make it back there.

Trump also threatened Iran on Truth Social with another strike, saying it could be even stronger than the previous one if Tehran did not stop financing Hezbollah in Lebanon. The US president also addressed Iranian President Masoud Pezeshkian indirectly, advising him to watch his words after statements about Tehran’s right to enrich uranium.
