Khashoggi, a columnist for The Washington Post, went missing in Turkey on October 2. According to the journalist's fiancee, he was invited to the Saudi consulate in Istanbul but never left the consulate building. Media reported that Turkish investigators believe the journalist was murdered inside the consulate, but Saudi Arabia claims that Khashoggi went missing after he left the building.
A number of states, including Germany, France, Spain and the United Kingdom, have expressed serious concerns over the journalist's disappearance. US President Donald Trump on Saturday threatened to "punish" Riyadh if it was proven to be behind the suspected killing.
