Iranian Foreign Affairs Minister Hossein Amir Abdollahian vowed on Saturday to make an "immediate" response to any "political" step at the meeting of the Board of Governors of the International Atomic Energy Agency scheduled to be held next week, on the background of the preparation of Western countries of a draft resolution urging Tehran to cooperate with the UN agency. This position comes one day after the United States said that it is preparing with three European countries (Germany, France and UK) a draft resolution urging Iran to "fully cooperate" with the agency, after it announced this week that Tehran had not provided enough clarifications about the reasons for finding traces of nuclear materials at its not authorized sites.
