Iran's Foreign Minister Hossein Amir-Abdollahian said he expects all parties to the Iran nuclear deal to demonstrate "seriousness" in restoring the accord.

Amir-Abdollahian was speaking with EU Foreign Policy Chief Josep Borrell after diplomats wrapped up their latest round of talks in Vienna on Monday. Iran and the United States had engaged in indirect talks mediated by the European Union on a new agreement.

Amir-Abdollahian expressed hope that "the other parties, especially the United States, adopt a realistic approach and avoid unconstructive comments." He noted that a final deal "must secure the rights and interests of the Iranian nation and guarantee effective and lasting sanctions relief."

While the Iranian negotiators were back home for consultation, the country's press speculated extensively about whether a deal was in the pipeline. "An ambiguous end to the Vienna talks," read a headline from the Reformist daily Arman-e-Emrouz. The paper noted, "The United States, unlike the European signatories, has been attempting to send the message that there is little hope for a new deal."
