Iran's chief nuclear negotiator Ali Bagheri Kani is seen leaving the Coburg Palais, venue of the Joint Comprehensive Plan of Action (JCPOA) meeting aimed at reviving the Iran nuclear deal, in Vienna on December 3, 2021. - Negotiations in Vienna aimed at reviving the Iran nuclear deal are to be suspended on December 3 so that European diplomats can review proposals by the Islamic republic, state media said. The talks would "most likely" resume on December 6 but the negotiating teams would need to remain in the Austrian capital to continue their work, the semi-official ISNA news agency said.
