VIENNA -- Top negotiators in renewed talks to revive the 2015 Iran nuclear deal indicated Sunday that they are optimistic about the possibility of reaching an agreement to impose limits on Tehran's uranium enrichment.

We stand 5 minutes or 5 seconds from the finish line, Russian Ambassador Mikhail Ulyanov told reporters outside Viennas Palais Coburg, four days into the talks. He said there are 3 or 4 issues left to be resolved.

They are sensitive, especially for Iranians and Americans, Ulyanov said. I cannot guarantee, but the impression is that we are moving in the right direction.

Enrique Mora, the European Unions top negotiator, also said he is absolutely optimistic about the talks progress so far.

We are advancing, and I expect we will close the negotiations soon, he told Iranian media.

Negotiators from Iran, the U.S. and the European Union resumed indirect talks over Tehrans tattered nuclear deal Thursday after a months-long standstill in negotiations.

Since the deals de facto collapse, Iran has been running advanced centrifuges and rapidly growing its stockpile of enriched uranium.

Iran struck the nuclear deal in 2015 with the U.S., France, Germany, Britain, Russia and China. The deal saw Iran agree to limit its enrichment of uranium under the watch of U.N. inspectors in exchange for the lifting of economic sanctions.

Then U.S. President Donald Trump unilaterally pulled the U.S. out of the accord in 2018, saying he would negotiate a stronger deal, but that didnt happen. Iran began breaking the deals terms a year later.
