The United Nations human rights agency called on Tuesday for international experts to be involved in an independent investigation into the killing of Saudi journalist Jamal Khashoggi, with access to evidence and witnesses. The agency's spokeswoman, Ravina Shamdasani, also urged Saudi Arabia to reveal the whereabouts of Khashoggi's body, saying that a forensic examination and autopsy were crucial elements in an investigation into the "shockingly brazen crime" carried out in the Saudi consulate in Istanbul on October 2.
