Iran once again declared that its national nuclear program is designed to generate electricity and that it does not aim to produce nuclear arms.

"Iran would have opted out of Non-Proliferation Treaty (NPT) if it had planned to produce nuclear arms," Iran said in a letter to Board of Governors of International Atomic Energy Agency (IAEA).

Iran forwarded a 131-page reply to the report of IAEA Director General Mohamed ElBaradei to the Board of Governors.

The reply has given note-to-note explanations to ElBaradei's report and said that Iran would proceed with cooperation with the UN specialized agency.

"Some exaggerations have been made in the report of the director general and Iran believes that Iranian nuclear program is being treated with political considerations rather than a technical approach which the UN specialized agency is expected to take," Iran said.

"A brief look at Mr. ElBaradei's report to Board of Governors indicated that the UN Agency has been influenced by a political propaganda campaign against Iranian nuclear program. It is easy to reach such a conclusion from legal and technical aspects of director-general's report," the letter said.

"The UN Agency is expected to do its work in a technical manner, but, Iranian nuclear program has been politicized in order to divert attention of the international community from the immediate and serious security concerns as a result of violation of article VI of the NPT, existence of the huge number of the nuclear warheads, recent progress in manufacture of new types of nuclear weapons by two Nuclear Weapon States and the last but not the least the potential nuclear threat by Israel, being the only-non-party to NPT in the strategic region of Middle East," the letter said.
