Iranian President Mahmoud Ahmadinejad on Wednesday toured various sections of Natanz Nuclear Facility and was briefed on the progress made by Iranian experts in making access to nuclear technology for peaceful use. The Iranian News Agency "IRNA" said the President delivered a speech at the gathering of the administrators in charge of the facility. Turning to the ongoing hue and cry aiming to deprive Iran of its right to use nuclear technology for peaceful purposes, he noted that what the enemies are afraid of is not production of nuclear bomb, given that in the world of today, nuclear weapons are of no use. "They are rather concerned over and panicked by self-sufficiency and knowledge of the Iranian nation and the progress of youth in the nuclear field," he added. Appreciating the progress made by the country in the field of peaceful nuclear technology, the president said, "There is no end to the work and we can always increase the speed of progress and decrease the side expenses by innovation, initiatives and inventions."
