TEHRAN (Tasnim) � An Iranian lawmaker cautioned the International Atomic Energy Agency (IAEA) to avoid impairing the credibility of a nuclear deal between Tehran and world powers by disclosing information on details of its cooperation with Iran.

Speaking to Tasnim on Sunday, Fathollah Hosseini called on the UN nuclear watchdog not to disclose the secret documents of cooperation with Iran.

He noted that the IAEA's failure to honor its commitments regarding confidentiality of the roadmap it has signed with Iran would taint the credibility of the Joint Comprehensive Plan of Action (JCPOA).

IAEA Director General Yukiya Amano and Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi on July 14 signed a roadmap in Vienna to resolve all the past and present outstanding issues related to Tehran's nuclear energy program.

On the same day, Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) also finalized the text of JCPOA, a lasting deal that would end more than a decade of impasse over Tehran's nuclear program.

The IAEA has been given the role of verifying Iran's commitments under the deal.

According the JCPOA, "The International Atomic Energy Agency (IAEA) will be requested to monitor and verify the voluntary nuclear-related measures as detailed in this JCPOA. The IAEA will be requested to provide regular updates to the Board of Governors, and as provided for in this JCPOA, to the UN Security Council. All relevant rules and regulations of the IAEA with regard to the protection of information will be fully observed by all parties involved."

Iran says the contents of the documents on cooperation with the UN nuclear watchdog are confidential and could not be made public.

The Iranian lawmaker's comments came while Amano has accepted an invitation to go to the US Senate Committee on Foreign Relations on Wednesday to discuss his agency's monitoring role in Iran following finalization of the text of JCPOA.

The IAEA said in a statement on Friday that Amano "will discuss the IAEA's role in verifying and monitoring nuclear-related measures under the Joint Comprehensive Plan of Action."

Meanwhile, some members of the US Congress, which is considering whether to approve the deal, have asked that more information be made public relating to the IAEA's part in verifying Iran's implementation of the pact.
