Saudi journalist Jamal Khashoggi, who wrote critically of the kingdom’s policies and Saudi Crown Prince Mohammed bin Salman, was killed in the Saudi consulate in Istanbul earlier this month.
Turkish officials claim that a 15-man team tortured, killed and dismembered the writer, while Saudi Arabia maintains the 59-year-old died in a “fistfight”.
Here are some key moments in the disappearance of the Washington Post columnist:
- September 2017:
The Post publishes the first column by Mr Khashoggi in its newspaper, in which the former royal court insider and longstanding journalist writes about going into self-imposed exile in the US over the rise of Prince Mohammed. His later columns criticise the prince and the kingdom’s direction.
- September 28 2018:
Over a year after the Post published his first column, Mr Khashoggi visits the Saudi consulate in Istanbul, seeking documents in order to get married.
He is later told to return on October 2, his fiancee Hatice Cengiz says.

Mr Khashoggi travels to London and speaks at a conference.

- October 2 2018 – the day of his disappearance
3.28am: A private plane arrives at Istanbul’s Ataturk Airport carrying some members of what Turkish media later refer to as a 15-member Saudi “assassination squad”, including a man officials describe as a forensics and “autopsy expert”. Others arrive via commercial flights, Turkish officials say.
1.14pm: Surveillance footage later leaked to Turkish media shows Mr Khashoggi walking into the main entrance of the Saudi consulate. No footage made public ever shows him leaving and his fiancee waits outside, pacing for hours.
3.07pm: Surveillance footage shows vehicles with diplomatic licence plates leaving the Saudi consulate for the consul general’s home just over a mile away.
7pm: A private plane just arrived from Saudi Arabia carries six members of the alleged Saudi squad from Istanbul to Cairo, returning to Riyadh the next day.
11pm: Seven members of the alleged Saudi squad leave on the other private jet to Dubai in the United Arab Emirates, which the next day returns to Riyadh. Two others leave by commercial flights.
