Iran rejected new peace talks with the United States, its state news agency reported on Sunday, hours after US President Donald Trump said he was sending envoys for talks in Pakistan and would launch new strikes on Iran unless it accepts his terms.

Trump posted on Truth Social that his envoys would arrive in Pakistan on Monday evening for negotiations, a timetable that would leave only a day for talks to make progress before a two-week ceasefire ends.

“We’re offering a very fair and reasonable DEAL, and I hope they take it because, if they don’t, the United States is going to knock out every single Power Plant, and every single Bridge, in Iran,” he wrote. “NO MORE MR. NICE GUY!”

Iran’s official IRNA news agency cited no specific source in its report that Iran had rejected the talks.

“Iran stated that its absence from the second round of talks stems from what it called Washington’s excessive demands, unrealistic expectations, constant shifts in stance, repeated contradictions, and the ongoing naval blockade, which it considers a breach of the ceasefire,” IRNA wrote.

The White House did not immediately respond to a request for comment on Iran’s rejection of the talks.

Earlier, a White House official said the US delegation would be headed by Vice President JD Vance, who led the war’s first peace talks a week ago, and also include Trump’s envoy Steven Witkoff and son-in-law Jared Kushner. Trump had initially told ABC News and MS Now that Vance would not go.
