A fresh round of peace talks between Iran and the United States now looks likely in the coming days as mediators scramble toextend a ceasefire set to expire on Wednesday.

In a Truth Social post on Sunday morning, US President Donald Trump said his representatives would be in Islamabad "tomorrow evening" for negotiations. He added that if Iran didn't accept the deal he offered, "the United States would knock out every single power plant, and every single bridge, in Iran."

Iranian parliament speaker and chief negotiator, Mohammad Baqer Qalibaf, said he had received new proposals from the United States but the two sides were far from a final deal.

DW asked Mehrzad Boroujerdi, an expert on Iranian politics and the Dean of the College of Arts and Sciences at the University of Missouri, Science and Technology, how close Iran and the United States were to a deal and whether both sides were simply buying time.
