Iran wants to continue negotiations with Britain, France and Germany despite an ultimatum by the European Union trio, state-television IRIB reported Saturday. An Iranian spokesman told IRIB that despite differences between the two sides over the issue, the talks Thursday in Vienna were held in an atmosphere free of tensions and should be continued in the same manner. "It is the strategy of the whole Islamic administration to avoid any unnecessary tensions," Hussein Mussavian said in an interview with IRIB. The E.U. trio presented an ultimatum to Iran Thursday to end its uranium enrichment programmes or risk the case being referred to the United Nations Security Council. Mussavian said that since initial talks last October in Teheran, "Iran has not been happy with what the Europeans did". But he added that the talks with the Europeans and the cooperation with the International Atomic Energy Agency (IAEA) have neutralized most of the charges by the United States on Iran's secret nuclear weapons projects. "The U.S. has charged us with already having nuclear weapons, that has however been cleared and the new demands are on hypothetical future projects," Mussavian said. Teheran has always insisted its nuclear technology was strictly peaceful. Following the talks Thursday in Vienna, the two sides are reportedly to meet again in Vienna and even in Teheran.
