Supreme Leader\'s advisor for foreign affairs Ali Akbar Velayati said here on Saturday that Iran’s nuclear activities have always been fully transparent. He made the remark in response to a question by a foreign correspondent asking whether Iran would provide full chance to the International Atomic Energy Agency (IAEA) inspectors to inspect Iran’s nuclear facilities. The IAEA senior inspectors are to arrive in Tehran on Sunday to inspect Iran’s nuclear facilities. Velayati said the inspectors are free to carry out their inspections within the framework of international regulations, stressing that they will be facing no restrictions in this regard. He reminded that the UN nuclear watchdog has for long installed its surveillance cameras in the Iranian nuclear centers and constantly monitors their activities.
