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.

– 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.

Surveillance footage is leaked of Mr Khashoggi and the alleged Saudi squad that killed him. Mr Khashoggi’s fiancee asks US president Donald Trump and first lady Melania Trump for help.

Mr Trump tells CBS’s 60 Minutes that “we’re going to get to the bottom of it, and there will be severe punishment” if Saudi Arabia is involved. The kingdom responds with a blistering attack against those who threaten it, as the manager of a Saudi-owned satellite news channel suggests the country could retaliate through its oil exports. The Saudi stock exchange plunges as much as 7% at one point.

– October 15:

A Turkish forensics team enters and searches the Saudi consulate, an extraordinary development as such diplomatic posts are considered sovereign soil. Mr Trump suggests after a call with Saudi King Salman that “rogue killers” could be responsible for Mr Khashoggi’s death. Mr Trump says his secretary of state Mike Pompeo will travel to the Middle East to investigate the case. Meanwhile, business leaders say they will not attend an upcoming economic summit in the kingdom which was the brainchild of Prince Mohammed.

– October 16:

A high-level Turkish official tells the Associated Press that “certain evidence” was found in the Saudi consulate proving Mr Khashoggi was killed there. Mr Pompeo arrives for meetings in Saudi Arabia with King Salman and Prince Mohammed. Meanwhile, Mr Trump compares the case to the appointment of now-US supreme court Justice Brett Kavanaugh during his confirmation hearing, saying: “Here we go again with ‘you’re guilty until proven innocent’.”
