Geneva (Switzerland): A UN investigator on Thursday urged United Nations to provide justice to slain journalist Jamal Khashoggi, recommending that the "perpetrators" and the "masterminds" behind the murder should be "tried".

Agnes Callamard, an academic who leads an international probe into the killing at the Saudi consulate in Istanbul on October 2, is expected to release her findings to the United Nations Rights Council before its next session in June.
