The spokesperson for the Atomic Energy Organization of Iran says the reports of the International Atomic Energy Agency (IAEA) are "politically motivated" and "ambiguous".
Behrouz Kamalvandi also said the UN nuclear agency's verification reports under the safeguards agreement indicate the fact that all nuclear activities of Iran are peaceful and there is no diversion in Tehran's nuclear program, IRNA reported.
In his opening statement to the board of governors of the UN nuclear watchdog on Thursday, IAEA Director General Yukiya Amano said, "The agency continues to verify the non-diversion of nuclear material declared by Iran under its Safeguards Agreement."
Amano also called on Iran "to increase its cooperation with the agency and to provide timely access to all relevant information, documentation, sites, material and personnel."
Kamalvandi said Iran is ready to allow the UN nuclear agency access to the western Marivan region, where an IAEA report in 2011 claimed explosives tests may have been carried out, to prove that Iran's nuclear activities are solely for peaceful purposes.
Ambassador to the IAEA Reza Najafi had made the same offer on Thursday. The IAEA said on Friday it would discuss Iran's offer for access to the Marivan region, but that it was not as straightforward as suggested by Tehran, Reuters reported.
"The situation regarding a visit to the Marivan region is not as simple as that conveyed by Iran. The agency will discuss the offer with Iran," IAEA spokeswoman Gill Tudor said, without elaborating.
