Iran's Atomic Energy Organization spokesman Ali Shirzadian said on Sunday that the Islamic Republic of Iran has declared all its nuclear sites to IAEA and there is no hidden project, IRNA reported.
Speaking to IRNA, he said the MKO has made hue and cry that Iran has an undeclared nuclear site in Qazvin which is totally fabricated.
"Spread of such rumors aims to satisfy ill-wishers and westerners who are to distort realities and disturb world public opinion on peaceful nature of Iran's nuclear activities", he said.
MKO on Thursday claimed that the Islamic Republic of Iran has set up a nuclear site in Abeyek in Qazvin proivnce without the knowledge of IAEA.
