Iran looks ahead to talks with UN envoy

With a first round of nuclear negotiations with world powers ending without agreement, Iranian officials looked ahead last night to parallel talks with the UN’s nuclear chief amid reminders that concessions by Tehran have limits.

The overall message from Iran closely mirrored the work-in-progress tone of US secretary of state John Kerry and other powerful envoys, who failed to seal a first-step accord during overtime talks in Geneva and but then quickly agreed to try again next week.

The administration of Iranian president Hassan Rouhani is emphasising that the talks are a work in progress.
