Saudi Crown Prince Mohammed bin Salman once discussed using “a bullet” on Jamal Khashoggi, despite the royal family trying to distance itself from the dissident Saudi journalist’s murder, according to a report.

Crown Prince Mohammed made the comment in a 2017 conversation intercepted by U.S. intelligence agencies, the New York Times reported Thursday. It was uncovered as the National Security Agency and other agencies examine the crown prince’s voice and text communications as part of an investigation into Khashoggi’s death.
