The spokesman for the Atomic Energy Organization of Iran says there is no option left for enemies but diplomacy in dealing with the country's nuclear industry.

The IAEA says samples taken from Natanz nuclear facility show Iran has enriched uranium to up to 63 percent, adding that the purity level is “consistent with the fluctuations” announced by the Islamic Republic.

Iran says it has started enriching its uranium supply to 60 percent purity in response to the sabotage of its nuclear site last weekend.
