(FILES) A picture taken on July 3, 2014 shows Vice President of the European Commission Catherine Margaret Ashton (L) and Iranian Foreign Minister Javad Mohammad Zarif (R) meeting during the so-called EU 5+1 talks with Iran at the UN headquarters in Vienna. Negotiators from Iran and six world powers meet in Vienna from November 18, 2014 for a final round of talks on securing a deal over Tehran’s nuclear program by a November 24 deadline. The five permanent members of the UN Security Council plus Germany (the P5+1) want Iran to scale down its nuclear activities in order to make any dash to make a bomb extremely difficult.
