VIENNA (Dispatches) -- Iran’s representative to Vienna-based international organizations on Friday raised the alarm at the occupying regime of Israel’s highly secretive nuclear activities as a threat to global security, saying the world community should pressure the regime into joining the Non-Proliferation Treaty (NPT) "swiftly” and "unconditionally.” Addressing a meeting of the 35-nation Board of Governors of the International Atomic Energy Agency (IAEA) on Friday, Kazem Gharibabadi warned that the Zionist regime has been expanding its clandestine nuclear capabilities in entire disregard of international rules and norms, something that poses a serious threat to global peace and stability.
