Iran nuclear talks could go either way – Kerry

US Secretary of State John Kerry has said negotiating teams are close to a historic agreement over Iran’s nuclear programme but cautioned that the talks could still go either way, and that Washington is still willing to walk away if an acceptable deal is not reached. “It is now time to see whether or not we are able to close an agreement,” Kerry told reporters on Sunday in Vienna, ahead of a July 7 deadline. “We have made genuine progress. We want a good agreement. We are not going to shave anywhere in the margins just to get to an agreement.” On Monday, Mohammad Javad Zarif , the Iranian foreign minister, said that some differences still remained between the Islamic republic and the six powers over the country’s disputed nuclear programme. “Still nothing is clear. … Some differences remain and we are trying and working hard,” Zarif told reporters.
