The Islamic Republic of Iran stressed on Tuesday that the West had no serious proof Tehran was developing nuclear weapons.

"There is no serious proof that Iran is going to create a nuclear warhead," Foreign Minister Ali Akbar Salehi said, responding to a question about the International Atomic Energy Agency report during a visit to neighboring Armenia.

The West and the United States are exerting pressure on Iran without serious arguments and proof," he said, ahead of a report by the UN atomic watchdog.

Diplomats have said that the report will focus on claims that the Islamic republic was putting fissile material in a warhead and on developing missiles.

Iran confirms its program is for peaceful ends only insisting that is its right under the Nuclear Nonproliferation Treaty (NPT) while Israel, which is believed to be the sole nuclear power in the Middle East with more than 200 nuclear heads, is not a signatory for this treaty.
