After issuing a plethora of fresh threats Sunday morning, President Donald Trump was issued a warning of his own from Iranian Parliament Speaker Mohammad Bagher Ghalibaf, who hours later warned Trump to “be careful” with his words amid the delicate ceasefire between the United States and Iran.As relayed by Fox News’ Trey Yingst, Trump threatened to “take over” both Iran and the Strait of Hormuz, while also issuing a vague threat that appeared to suggest he may order the assassination of Iranian peace negotiators, Ghalibaf included. In a statement published on social media, Ghalibaf hit back at Trump and urged him to tread carefully.“Don't they think to themselves that if their threats had any effect, they wouldn't have reached the point of despair today? We don't count on the threats of the Americans,” Ghalibaf wrote in his statement, according to an English translation from Hebrew by Google Translate.“They better be careful with their statements, our armed forces are ready to respond in another way. Whatever they say, we are the ones who will act.”Trump’s threats Sunday morning have already had an impact on the negotiations being held in Switzerland. An Iranian news outlet reported that the Iranian delegation left the negotiation venue in protest of Trump’s threats, and MeidasTouch, a progressive media outlet, argued that Trump was “single-handedly destroying the entire peace process.”🚨🚨 BREAKING: Iran's negotiators have LEFT the venue in protest of Trump's threats, per Tasnim.Trump is single-handedly destroying the entire peace process.— MeidasTouch (@MeidasTouch) June 21, 2026
