Turkish officials suspect Khashoggi was killed and dismembered inside the consulate by Saudi agents on October 2.
The source said: "The consul himself was taken out of the room". Salah, who has reportedly been under a travel ban since previous year, stared coldly into the eyes of the man accused of plotting his father's murder as they shook hands.
They are said to include "Saudi royal guards, intelligence officers, soldiers and an autopsy expert". The Saudi government insists the King and Crown Prince had no prior knowledge of the plan to kill Khashoggi.
The comments come as Turkish President Recep Tayyip Erdogan demanded to know who gave the order for Khashoggi's killing in his country and the location of the slain journalist's corpse. Erdogan asked. "We are seeking answers to this".

Senior Saudi leaders attending the conference have admitted Khashoggi's killing has had an impact.
The Turkish president didn't mention the audio recording that Turkish media said had recorded Khashoggi's murder. Mnuchin met Monday with Crown Prince Mohammed Bin Salman - who hasn't directly addressed the killing of Khashoggi - at a meeting separate to the investment conference.
Erdogan vowed Turkey would continue in its pursuit of the truth. If the information that the body was given to a local cooperator, co-conspirator-and this is information by an authority, by the way-now my question is: "Who is this local co-conspirator?"
Future Investment Initiative (FII), dubbed "Davos in the desert", is being held in the capital Riyadh as part of bin Salman's much-touted Vision 2030 and is meant to attract foreign investments in the kingdom heavily dependent on oil revenues.

He described Khashoggi's death as murder.
The €416 million ($479 million/£367 million) of arms exports Germany approved to Saudi Arabia for this year pales in comparison to the arrangement between the USA and the kingdom. "Such reflexes alone show that there is much suspicion about the issue".
In a heartfelt New York Times piece which ran earlier this month, the doctoral student said the couple had been "cheerful" the morning they travelled to the consulate.
Merkel appeared dubious of Saudi Arabia's claims that Khashoggi died due to a rogue operation gone wrong, telling reporters in Berlin on Sunday, according to Politico, that there was an "urgent need for further clarification".
Other senior German politicians, including foreign minister Heiko Maas and foreign affairs committee chairman Norbert Röttgen, have also called for a halt in arms sales to Saudi Arabia, citing dissatisfaction with Riyadh's explanation of how Khashoggi died inside the Saudi consulate in Istanbul.
Erdogan said 15 Saudi officials arrived in the country shortly before Khashoggi's death and that a man, apparently dressed in the writer's clothes, acted as a possible decoy by walking out of the consulate on the day of the disappearance.More news: No room for extravagance at low-priced Premier Inn
