RIYADH, Saudi Arabia - Saudi Arabia's crown prince, Mohammed bin Salman, appeared on "60 Minutes" Sunday, offering a series of denials about human-rights abuses and any personal role in the murder of journalist Jamal Khashoggi. PBS' Frontline provides a deep dive into Saudi politics -- as well as Khashoggi's death almost exactly a year after he was brutally killed and dismembered within the Saudi consulate in Turkey -- with "The Crown Prince of Saudi Arabia," a two-hour documentary premiering this week and already available online. That portion actually feeds directly into "Saudi Women's Driving School." Frontline's "The Crown Prince of Saudi Arabia" premieres Oct. 1 on PBS. "Saudi Women's Driving School" premieres Oct. 24 on HBO, which, like CNN, is a unit of WarnerMedia.
