A spokesperson from the US state department said on Friday that efforts to revive the Iran nuclear deal remain far from certain, and Tehran will have to decide whether it wants to reach a deal soon.

"[A]t this point a deal remains far from certain. Iran needs to decide whether it insists on extraneous conditions and whether it wants to conclude a deal quickly, which we believe would serve all sides’ interests," the spokesperson said in a statement to Sputnik. "We and our partners are ready, and have been for some time. It's now up to Iran."

Sources close to the Iranian delegation in the Vienna Talks said on Friday that the Vienna talks to revive the JCPOA have again picked up pace.

The sources added, in their statement to Al Mayadeen, that it's too soon to say "that we are close to reaching a deal," noting that this still needs a lot of discussion.

They further said that the Europeans are in a hurry to reach a deal because of the crisis they are going through, brought on by the war in Ukraine, and their desperate need for Iranian gas and oil.
