Mustafa al-Madani left the consulate wearing Mr Khashoggi's glasses and clothes.
Also yesterday, it was reported that Peter Voser, chairman of Swiss engineering giant ABB, had suspended his membership of the mega-city's board, which was announced on 9 October as alarm and anger mounted over the disappearance of Khashoggi after he entered the Saudi consulate in Istanbul a week earlier.
"Indeed such reports are also incompatible with Saudi Arabia's own stated goal of progress and renewal".
In a speech on Sunday, Turkish President Tayyip Erdogan appeared to suggest he was getting ready to release some information about the Turkish investigation, and would do so at his weekly speech on Tuesday to members of his ruling AK Party.
Saudi Arabia's claim that a dissident journalist died in a fight at one of its consulates is not credible, Jeremy Hunt has said. Widodo's concerns were relayed by Indonesia's foreign minister following the meeting.
The minister, Retno Marsudi, told reporters that "the president is deeply concerned with the Khashoggi case and Indonesia hopes that the ongoing investigation will be transparent and meticulous". Retno said the visit was scheduled after the Saudi monarch visited Indonesia, the world's most populous Muslim-majority nation, in March a year ago. After he initially seemed willing to believe Saudi accounts, the president now says "obviously there has been deception, and there has been lies".
The images contradict Saudi's admission on Saturday that the writer died inside the consulate during a "fistfight".
"A lot of the reforms they've been making there to help us track down the terror financing and also to push back against the people who are perverting the religion, have been very historic over the previous year", he said.
The Turkish officials spoke on condition of anonymity in line with government regulations.
Turkish officials say Khashoggi was tortured, murdered and dismembered by a squad of 15 Saudi hit men shortly after entering the Saudi Consulate in Istanbul on October 2.
The crown prince has "now crossed a line and there has to be a punishment and a price paid for that", Corker said.
The source said dressing Madani up as Khashoggi and claiming he left the building was a plan hatched before Khashoggi's death, and shows that his killing was premeditated.
Turkish officials suspect Mr Khashoggi was killed inside the consulate by the team of Saudi agents and his body cut up.
The murder has sparked global outcry, with German Chancellor Angela Merkel vowing on Sunday to suspend arms exports to Riyadh until uncertainty over the fate of Khashoggi vanishes.
Mr Jubeir said the Saudis offered its condolences to Mr Khashoggi's family.
Prime Minister Theresa May condemned the killing "in the strongest possible terms" and added "we must get to the truth of what happened".
"I believe the blood of Jamal will create peace in the region if Bin Salman is punished".
In a sign of growing pressure on Saudi Arabia, Turkey said it will announce details of its investigation into the killing of journalist Jamal Khashoggi on Tuesday and United States congressional leaders said the Gulf kingdom - in particular its crown prince - should face severe consequences for the death of the writer in the Saudi consulate in Istanbul. King Salman, 82, has handed the day-to-day running of Saudi Arabia to him.
That's according to statements published early Monday by the state-run Saudi Press Agency.
