Iranian state radio quoted President Mahmoud Ahmadinejad as saying the latest round of talks between Iran and world powers are "a step ahead."

The Sunday report also quotes the Iranian leader as saying his country's official assessment of the talks will soon be announced. He did not give a precise date.

Ahmadineajd's remarks are the first after the meeting Saturday in Geneva between Iran's top nuclear negotiator and envoys from Washington and five other world powers.

The six have called on Iran to freeze uranium enrichment, arguing that it is designed to make nuclear weapons.

Iran has rejected the demand, as it has repeatedly done in the past. It says its uranium enrichment program is for peaceful purposes.
