Iran met in Qatar with European Union mediator Enrique Mora as part of efforts to revive its 2015 nuclear pact with world powers, as Tehran and Washington seek to cool tensions with a mutual "understanding" to help end the deadlock.
Having failed to revive the deal in indirect talks that have stalled since September, Iranian and Western officials have met repeatedly in recent weeks to sketch out steps that could curb Iran's fast advancing nuclear work, free some U.S. and European detainees held in Iran and unfreeze some Iranian assets abroad.
"(I) had a serious and constructive meeting with Mora in Doha. We exchanged views and discussed a range of issues including negotiations on sanctions lifting," Iranian chief nuclear negotiator Ali Bagheri Kani said on Twitter, without elaborating.
Mora tweeted that the Doha talks were "intense" and had touched on "a range of difficult bilateral, regional and international issues, including the way forward on the JCPOA" - the Joint Comprehensive Plan of Action, as the nuclear deal is officially called.
EU spokesperson Peter Stano said the bloc was "keeping diplomatic channels open, including through this meeting in Doha, to address all issues of concern with Iran".
