Iran and six world powers meeting in Geneva have reached a deal on Tehran's nuclear programme, foreign ministers say.
Negotiators from the UK, US, Russia, China, France and Germany want Iran to stop enriching uranium in return for a loosening of sanctions.
Iranian Foreign Minister Mohammad Javad Zarif said he was "confident we can move forward: this is only the first step".
