Iran-U.S. nuclear talks in Qatar end without making progress

European Union mediator Enrique Mora on Twitter described as “intense” the two days of talks in Doha.

Indirect negotiations between Iran and the U.S. over Tehran's tattered nuclear deal with world powers ended on Wednesday in Qatar after failing to make significant progress amid a growing crisis over the Islamic Republic's atomic program, diplomats said.

The Doha talks broke up after two days without any sign of a breakthrough, months after talks in Vienna among all of the deal's parties went on “pause." In the time since, Iran shut off surveillance cameras of international inspectors and now has enough high-enriched uranium to potentially fashion into at least one nuclear bomb if it chose.

And with Iran and the U.S. blaming each other for the talks' failure, it remains unclear when — or if — there will be another round of negotiations.

European Union mediator Enrique Mora on Twitter described as “intense” the two days of talks in Doha.

"Unfortunately, not yet the progress the EU team as coordinator had hoped-for," Mora wrote. “We will keep working with even greater urgency to bring back on track a key deal for non-proliferation and regional stability.”

Mora's comments came hours after the semiofficial Tasnim news agency, believed to be close to Iran’s hard-line Revolutionary Guard, described the negotiations as finished hours before they ended and having “no effect on breaking the deadlock in the talks.”

Tasnim claimed that the American position did not include “a guarantee for Iran benefiting economically from the deal,” quoting what it described as unnamed “informed sources.”
