Iranian negotiators said Friday that progress was being made in nuclear talks in Geneva with world powers as both sides work on bridging differences to sign an elusive deal. "Differences of opinion remain and we are negotiating over them. God willing we will reach a result," Foreign Minister Mohammad Javad Zarif said in statements carried by Iranian media, after a one-hour meeting with EU foreign policy chief Catherine Ashton. Deputy Foreign Minister Majid Takht-e Ravanchi, who also attended the meeting, added: "We felt there was progress in the talks today" with the six world powers.
