Here is a summary of events in the year since journalist Jamal Khashoggi was killed by Saudi agents in the kingdom's Istanbul consulate, an affair that shocked the world.
The Washington Post contributor, who took refuge in the United States in 2017, is recorded on camera entering the Saudi consulate in Istanbul on October 2, 2018.
His fiancee waits outside but he never emerges.
The following day, the Post reports him missing.
In an interview with Bloomberg published on October 5, Saudi Crown Prince Mohammed bin Salman says Khashoggi is not inside the consulate and: "We have nothing to hide."
A source close to the Turkish government says the next day police believe he was murdered inside the premises "by a team especially sent to Istanbul and who left the same day".
Riyadh calls the claim "baseless".
On October 7, The Washington Post cites a US official as saying Khashoggi's body "was likely dismembered, removed in boxes and flown out of the country".
The New York Times says a suspect in the disappearance was identified by Turkey as being from Prince Mohammed's inner circle. Three other suspects are linked to his security team.
On October 20, Riyadh finally admits Khashoggi was killed inside the consulate, claiming this was after a "brawl".
Saudi Foreign Minister Adel al-Jubeir tells Fox News on October 21 there had been a "tremendous mistake" and those responsible acted "outside the scope of their authority".
Turkish President Recep Tayyip Erdogan on October 23 says Khashoggi's "savage" murder was carried out by a 15-person team from Riyadh.
On October 24, the crown prince says the affair is "very painful for all Saudis, it's a repulsive incident".
On October 31, Turkey's chief prosecutor says Khashoggi was strangled as soon as he entered the consulate, his body dismembered and destroyed.
On November 2, Erdogan says the order for the murder came from "the highest levels" of the Saudi government.
On November 15, Washington announces sanctions against 17 Saudis allegedly involved. Germany, France and Canada follow suit.
The Washington Post on November 16 quotes anonymous sources as saying the CIA had concluded the crown prince was involved in the murder plot.
But Trump says the CIA has "nothing definitive".
On December 4, Republican senators say after a CIA briefing that they firmly believe the crown prince was complicit.
On December 13, the Senate adopts a resolution holding him responsible.
On January 3, the trial of 11 accused opens with Saudi Arabia's attorney general seeking the death penalty for five of them.
On February 8, the Saudi foreign minister insists Prince Mohammed was not involved and says blaming him would be crossing a "red line".
On June 19, independent UN special rapporteur Agnes Callamard says there is "credible evidence" linking the crown prince to the killing.
She calls for an international criminal investigation.
Callamard's inquiry also finds that the closed-door trial of the 11 suspects did not meet global standards and should be stopped.
On September 26, US television PBS quotes the prince as insisting, in comments to a reporter two months after the murder, that it was executed without his knowledge but, "I get all the responsibility because it happened under my watch."
In an interview with CBS's 60 Minutes aired September 29, he again denies having advanced warning of Khashoggi's killing but says he "took full responsibility as a leader in Saudi Arabia".
