Talks between Iran and world powers aimed at finalizing a deal over Tehran’s nuclear program could go beyond a June 30 deadline

Talks between Iran and world powers aimed at finalizing a deal over Tehran's nuclear program could go beyond a June 30 deadline, a senior Iranian negotiator said Wednesday.
  
"We are not at the point where we can say that negotiations will be completed quickly -- they will continue until the deadline and could continue beyond that," Abbas Araqchi was quoted as saying by the official IRNA news agency.
  
Araqchi has been attending a fresh round of talks between Iranian representatives and officials from the P5+1 group -- Britain, China, France, Russia, the United States plus Germany -- which got under way in Vienna on Tuesday.
  
The two sides signed a framework agreement on April 2 and aim to seal a final deal by the end of next month.
  
"We are not bound by the schedule. We are trying to have a good agreement with all the details meeting our expectations," Araghchi said, describing the efforts to draw up a final text as "hard work".
  
Iranian media quoted deputy oil minister Amirhossein Zamani-Nia as saying on Monday that 20 pages of the text had been written "but there are still disagreements and 30 percent of the work remains to be done."
