Nuclear talks between Iran and six world powers have virtually stalled and a deadline for a final deal may have to be postponed again, Russian news agency TASS quoted a diplomatic source as saying on Friday.
Iran and the powers – the United States, Russia, China, France, Britain and Germany – are trying to reach a settlement by June 30 under which Iran would curb its nuclear program in exchange for relief from economic sanctions.
The latest round of discussions in Vienna on Friday had made no significant progress, the source from one of the missions said, according to TASS. "The process has virtually stalled, there is risk that the deadline will have to be postponed again," the source added.
"I'm not going to characterize the current state of the talks," Jeff Rathke, a State Department spokesman, said in response to the comments from Moscow on Friday. "We've said all along that we're not going to negotiate in public."
"We remain of the view that it is possible to conclude the talks by June 30," Rathke continued. "That remains our focus."
