The latest round of talks between Iran and other parties to the 2015 nuclear deal in Vienna ended on Friday without any significant breakthrough.
The parties — Iran and the P4+1 countries — are expected to reconvene in the Austrian capital next week after holding consultations in their respective capitals.
The decision was taken after a meeting of the joint commission of the nuclear deal, also known as the joint comprehensive plan of action (JCPOA), in the afternoon.
Iran's lead negotiator, Ali Bagheri-Kani, told reporters after the meeting that other parties — most notably the Europeans — felt the need to hold consultations with their capitals before taking a call on Iran's draft proposals.
He said the Iranian delegation during the meeting stressed that its two proposals — on lifting of sanctions and the nuclear commitments — were on the table.
The proposals were submitted by the Iranian delegation on Thursday after four days of intense deliberations marked by tensions.
In his remarks on Thursday, Bagheri said the European parties need to "study" the two draft proposals and return for "serious discussions," and stressed on lifting of sanctions before discussions on nuclear related issues.
