UN chief should launch international probe over Khashoggi murder: rights expert

United Nations Secretary-General Antonio Guterres should launch an international criminal investigation into the killing of Saudi journalist Jamal Khashoggi last October, an independent rights expert said Wednesday. In a fresh report on the killing, UN special rapporteur on extrajudicial, summary or arbitrary executions Agnes Callamard urged Guterres to "initiate a follow-up criminal investigation into the killing of Mr. Khashoggi to build-up strong files on each of the alleged perpetrators and identify mechanisms for formal accountability, such as an ad hoc or hybrid tribunal."
