Officials from Iran and Britain, France and Germany were due Thursday to hold nuclear talks in Vienna towards reaching a potentially historic accord by November.

The quartet meeting between senior Iranian nuclear negotiator, Sayyed Abbas Araqchi, and the representatives of France, Britain and Germany will take place within the framework of nuclear talks in the Austrian capital on Thursday  
  
The closed-door discussions in the Austrian capital, announced by EU foreign policy chief Catherine Ashton's office, follow bilateral US-Iranian discussions in Geneva last week.
  
A US State Department spokeswoman told reporters Tuesday that those talks in Switzerland were an "in-depth exchange on the core issues", without giving further details.
  
The recent diplomatic flurry also saw Iranian Foreign Minister Mohammad Javad Zarif fly to Moscow, Brussels and Paris as well as Rome to meet Ashton's successor from November 1, Federica Mogherini.

Iran and the five permanent members of the UN Security Council plus Germany are expected to resume negotiations over a final deal on the Islamic Republic’s nuclear energy program on the sidelines of the United Nations General Assembly session in New York on September 18.
