Iran and six world powers meeting in Geneva have reached a deal on Tehran’s nuclear programme, foreign ministers say.
No details have been released about the agreement, which has been reached after five days of negotiations.
Negotiators from the UK, US, Russia, China, France and Germany want Iran to stop enriching uranium in return for a loosening of sanctions.
Iran had earlier said it insisted on a “right to enrichment” in any deal.
This deal may be the most significant agreement between the world powers and Iran for a decade, says the BBC’s Iran correspondent, James Reynolds, who is at the talks in Geneva.
