Nuclear deal to open new horizons: Rouhani

The historic deal came after five days of intensive negotiations between Iranian interlocutors and P5+1

Iran's President Hassan Rouhani hailed an agreement with world powers over Tehran's nuclear drive, saying it would "open new horizons".

"Constructive engagement (in addition to) tireless efforts by negotiating teams are to open new horizons," Rouhani said on Twitter after intensive talks in Geneva produced a long-elusive accord.

Rouhani said the deal had been made possible due to "Iranian people's vote for moderation", referring to his surprise election victory in June.

The historic deal came after five days of intensive negotiations between Iranian interlocutors and high-ranking delegations from the the United States, Britain, France, China and Russia plus Germany in the grouping known as the P5+1.

The talks had hit snags over few points of difference, including Iran's insistence to have what it calls its "right" to enrich uranium to be recognised by the six major powers.

The White House said such a right was not inserted in the deal, while a senior Iranian negotiator, Abbas Araqchi, said Iran's "enrichment programme" had been recognised.

"Our enrichment programme has been recognised," Araqchi, a deputy foreign minister, said on Twitter but did not elaborate.

His boss Mohammad Javad Zarif said on Facebook that Iran's nuclear activities were to continue while "sanctions were not in decline".
