On 2 October 2018, Jamal Khashoggi, a US-based journalist and critic of Saudi Arabia's government, walked into the Saudi consulate in Istanbul, where he was murdered.
In the months that followed, conflicting narratives emerged over how he died, what happened to his remains, and who was responsible.
Saudi officials said the journalist was killed in a "rogue operation" by a team of agents sent to persuade him to return to the kingdom, while Turkish officials said the agents acted on orders from the highest levels of the Saudi government.
