Indirect talks between Iran and the United States to break an impasse over how to revive Tehran's 2015 nuclear pact with major powers have ended, EU's envoy Enrique Mora tweeted on Wednesday.
"Unfortunately, not yet the progress the EU team as coordinator had hoped for. We will keep working with even greater urgency to bring back on track a key deal for non-proliferation and regional stability," Mora said.
The talks were aimed at overcoming differences over how to salvage a 2015 nuclear pact between Iran and world powers.
Earlier, Iran's semi-official Tasnim news agency had reported that the negotiations in Doha had ended without result.
"The two-day talks are not over yet and later today Iran's top nuclear negotiator and the EU's envoy Enrique Mora will meet again," ministry spokesman Naser Kanani said, according to Iranian state media.
"Talks continue in a serious and business-like atmosphere."

The talks started on Tuesday with Mora as the coordinator, shuttling between Iran's Ali Bagheri Kani and Washington's special Iran envoy Rob Malley. They are trying to break a months-long impasse that has stalled negotiations in Vienna to reinstate the 2015 pact.
"What prevented these negotiations from coming to fruition is the US insistence on its proposed draft text in Vienna that excludes any guarantee for Iran's economic benefits," Tasnim said, citing informed sources at the talks.

Then-US president Donald Trump ditched the pact in 2018 and reimposed crippling sanctions on Iran's economy. A year later, Tehran reacted by gradually breaching nuclear limits of the deal.
Over 11 months of talks between Tehran and major powers to revive their nuclear deal stalled in March, chiefly over Tehran's insistence that Washington removes the Islamic Revolutionary Guards Corps (IRGC), its elite security force, from the US Foreign Terrorist Organization (FTO) list.
