Only "narrow gaps" remain in talks between world powers and Iran but the momentum must not be lost, the UK foreign secretary says.
The talks on Saturday failed to reach an agreement on Tehran's nuclear programme in return for limited relief from economic sanctions. They are due to resume on 20 November.
Speaking to The Andrew Marr Show, William Hague said a lot of progress had been made but admitted that the talks had been "formidably difficult".
