Iran told the US in talks last week it was ready to accept some limits on uranium enrichment but needed guarantees Trump would not abandon a nuclear pact. However, Iran vowed it would never agree to dismantle its centrifuges for enriching uranium. The two countries are set to hold a second round of talks in Rome. Trump reiterated that he would not allow Iran to get nuclear weapons. Tehran's red lines, mandated by Supreme Leader Ayatollah Ali Khamenei, could not be compromised in the talks, according to an anonymous Iranian official.
