Iran names a new supreme leader. What to know about the successor to the Ayatollah Ali Khamenei

Mojtaba Khamenei, a son of Iran’s late supreme leader, has been named as the Islamic Republic’s next ruler, authorities announced Monday, as Tehran widened its attacks across the Mideast to strike oil and water facilities crucial to its desert sheikdoms.

With Iran’s theocracy under assault by the U.S. and Israel for more than a week, the country’s Assembly of Experts chose as the next supreme leader a secretive, 56-year-old cleric who maintains close ties to the country’s paramilitary Revolutionary Guard.
