The head of Iran's nuclear negotiators has warned that the country's incoming president may reverse an agreement to freeze uranium enrichment activities.
Hassan Rohani told an Iranian daily he believes elected President Mahmoud Ahmadinejad will remain committed to nuclear talks with the European Union.
But he says the new president has a different view on the enrichment freeze, and may implement a change in a new round of talks with EU diplomats next month.
Tuesday, Mr. Ahmadinejad vowed "new measures" in nuclear talks when he takes over Iran's government on August 3.
EU officials have been offering economic incentives if Iran agrees to end uranium enrichment, amid fears the Islamic Republic may develop a nuclear weapon.
Tehran insists its program is for peaceful ends.
