The world's journalists gather in the Austrian capital, in the dry cold of Vienna, waiting for news about the negotiations on the Iranian nuclear deal: have they progressed, or will the negotiators leave the table and return to their capitals to discuss the developments of the negotiations?

In this episode of "After Yesterday", Khadija Ben Qena hosts Al Jazeera journalist Ali Hashem, who specializes in Iranian affairs and international Iranian politics.

Hashem covered the Iranian nuclear negotiations in 2015, and covers the recent negotiations, and in this episode he informs us about the scenes of the negotiations before and today: How do the Iranians negotiate?

How do US officials confront them?

And what does the atmosphere look like inside the negotiating rooms, with the presence of a new negotiating team on both sides?

The episode discusses these questions, reviews the atmosphere and details of the negotiations, and its agenda that delays the completion of the agreement.
