Tehran took offense at the US President Donald Trump's threat to attack and his warning that Iran's president should watch what he says.Trump's comments complicated efforts by US Vice President JD Vance and mediators Pakistan and Qatar to keep Iran engaged in discussions meant to address long-standing issues like Tehran's nuclear program, the Strait of Hormuz, the unfreezing of billions of dollars in Iranian assets and end of Israeli attacks on Lebanon.“Iran must immediately stop their highly paid PROXIES in Lebanon from causing trouble,” Trump said on social media. “If they don’t, we’ll hit Iran very hard again, just like we did last week, only harder!!!”Following Trump's comments, Iran's lead negotiator, Mohammad Bagher Qalibaf said, “They would do better to be careful about their statements. Our armed forces are prepared to respond to them in a different manner. They may keep talking, it is we who act.”Iranian state media as quoted by AP said talks had entered a “difficult phase” and recessed after the “publication of an insulting message by the US President.” The Iranian delegation then met with Qatari mediators and left the negotiating site, state media reported.
