Deputy Foreign Minister Abbas Araqchi, Head of Atomic Energy Organization of Iran(AEOI) Ali Akbar Salehi as well as Spokesman of the AEOI Behrouz Kamalvandi are members of Iranian delegation accompanying Zarif.
According to dispatches, US Secretary of State John Kerry will be in Vienna, Austria on Saturday to meet Zarif and EU foreign policy chief Federica Mogherini over the Iran nuclear deal.
Kerry, Zarif and Mogherini will discuss the nuclear agreement, dubbed the Joint Comprehensive Plan of Action (JCPOA), on Saturday, State Department Spokesman Mark Toner said on Friday.
'As we've said, all parties have continued making steady progress toward 'Implementation Day' of the JCPOA, which will ensure the exclusively peaceful nature of Iran's nuclear program,' Toner said.
Kerry's trip comes as the UN nuclear agency is expected to verify Tehran’s compliance with its obligations under the JCPOA reached with six world powers last July.
