An independent U.N. human rights expert investigating the killing of Saudi journalist Jamal Khashoggi is recommending an investigation into the possible role of Saudi Crown Prince Mohammed bin Salman, citing "credible evidence."

Agnes Callamard released a 101-page report into the October killing of Khashoggi at the Saudi consulate in Istanbul that lays out dozens of recommendations. It calls on U.N. bodies or Secretary-General Antonio Guterres to "demand" a follow-up criminal investigation.

Callamard noted the "extreme sensitivity" of considering the criminal responsibility of the crown prince, as well as Saud Alqahtani, a senior adviser to the Saudi royal court who has not been charged.

"No conclusion is made as to guilt," she wrote of the two men. "The only conclusion made is that there is credible evidence meriting further investigation."
