Iran won't permit its diplomats to negotiate with European nations over its nuclear program if their goal is to deprive Iran of the right to enrich uranium, Iran's top nuclear negotiator said Monday. Hasan Rowhani said, however, Iran was prepared to negotiate suspending some of its nuclear activities. "From a tactical point of view, such as how long to continue suspension, it's negotiable," Rowhani told state-run television. "But if the discussion is about depriving us of our legitimate rights, it's not negotiable. Our negotiating team is not authorized to discuss this either with the Europeans or others," Rowhani said.
