Iranians head to the polls Friday to vote in the Islamic Republic’s presidential election, casting ballots in a contest largely seen as a referendum on the country’s nuclear deal with world powers. Rouhani, 68, is a moderate cleric elected in 2013 on pledges of greater personal freedoms and improved relations with the West. His government negotiated the 2015 nuclear deal, which saw Iran accept curbs on its nuclear program in exchange for relief from crippling international sanctions. (AP/RSS Photo/Vahid Salemi, File)
