Iran says 'difficult road to go' to reach nuclear deal with world powers

VIENNA - Differences in the positions of Iran and world powers over Tehran's nuclear program remain big and they face a "difficult road" to reach a deal by a late November deadline, a senior Iranian negotiator said on Thursday.
Deputy Foreign Minister Abbas Araqchi spoke to reporters after a day of talks in Vienna with the three European members of the group of six major powers that is seeking to negotiate an end to a decade-old nuclear dispute with Iran.
Asked how big the differences were, he said: "Still big."
