Iran's right to enrich uranium is not negotiable, according to Foreign Minister Abbas Araqchi. Talks between Iran and the United States are set to take place in Rome this weekend, with the first round of talks described as positive and constructive. Western powers claim that Iran is refining uranium to a level suitable for atomic bomb fuel, while Iran denies seeking nuclear weapons. The second round of talks was originally planned to take place in Oman, but has been moved to Rome.
