TEHRAN, Iran — Iranians across the Islamic Republic voted Friday in the country’s first election since its landmark nuclear deal with world powers, deciding whether to further empower its moderate president or side with hard-liners long suspicious of the West.

The election for Iran’s parliament and a clerical body known as the Assembly of Experts hinges on both the policies of President Hassan Rouhani, as well as Iranians worries about the country’s economy, long battered by international sanctions.
