Rough cut (No reporter narration). Story: The six world powers seeking to negotiate an historic agreement with Iran to curb its nuclear program plan to carry on negotiating beyond a Tuesday deadline, a senior U.S. official said on Sunday (June 28). Iranian Foreign Minister Mohammad Javad Zarif was to leave Vienna and return to Tehran for consultations with the country's leadership on the state of negotiations, Iran said. The U.S. official, who spoke to reporters on condition of anonymity, said Washington was not troubled by Zarif's decision to return to Tehran overnight, saying it was always expected that ministers would come and go from Vienna as the talks heated up. Officials from both sides said big differences still remained. European Union foreign policy chief Frederica Mogherini said earlier on Sunday it was not impossible to get an accord by the self-imposed deadline but that a few extra days may be needed. "The reasons for having this agreement done are still there, probably now more than ever," she said, adding that the security of the world is at stake. British Foreign Secretary John Hammond said there are significant challenges that lie ahead. "There are red lines that we cannot cross and some very difficult decisions, tough choices are going to have to be made by all of us if we are going to get to a deal over the next few days," said Hammond. "No deal is better than a bad deal." The main differences are on the pace and timing of sanctions relief for Iran and on the nature of monitoring mechanisms to ensure Tehran does not cheat on any agreement. U.S. and European negotiators also want to ensure there is a mechanism for restoring sanctions if Tehran fails to meet its commitments under any future accord.
