Iran’s top nuclear negotiator predicts that talks in Vienna between Tehran and other countries on a potential revival of the 2015 nuclear accord are unlikely to conclude this week.

The fifth round of talks between Iran and the remaining signatories of the nuclear deal, known as the JCPOA concludes in Vienna.

Russia’s representative to the international organizations in Vienna says talks underway in the Austrian capital on a potential revival of the 2015 Iran nuclear deal may need “additional time” to reach a breakthrough.

Iran’s parliament speaker says the IAEA will no longer access images of the country’s nuclear sites because a three-month deal between the two sides expired on Saturday.

Iran says “good progress” has been made in Vienna talks, but participants need to return home for consultations on certain key issues.

A political analyst says the US wants to have it both ways, and partially remove sanctions against Iran but keep most of them in place.

A senior US National Security Council (NSC) official says Washington will not take pressure off until Iran’s nuclear program is capped.

A political commentator says the recent act of sabotage at Iran’s Natanz nuclear facility gives Iran the right to remarkably increase the remedial measures it has taken in the wake of United States’ unilateral withdrawal from the 2015 nuclear deal.

Russian Foreign Minister Sergei Lavrov says Moscow and Tehran are cooperating closely to make sure that the 2015 Iran nuclear deal is implemented in full.

The latest round of talks on the 2015 Iran nuclear deal, formally known as the Joint Comprehensive Plan of Action, JCPOA, ended with no tangible result in Vienna.
