TEHRAN, IRAN - MAY 19: Voters gather outside a polling station to cast their ballots for the presidential election on May 19, 2017 in Tehran, Iran. Millions of Iranians voted late into the night Friday to decide whether incumbent President Hassan Rouhani deserves another four years in office after securing a landmark nuclear deal, or if the sluggish economy demands a new hard-line leader who could return the country to a more confrontational path with the West.
