Saudi officials initially insisted Khashoggi had left the consulate, then said he died in an unplanned "rogue operation". His body has yet to be recovered. "All I'm waiting for is for the investigation to be over so the facts can turn out".
A pro-government newspaper, Sabah, published news of the Saudi cleanup team and photographs of two of its members, whom it identified as a chemist and a toxicologist, who visited the Saudi consulate where Khashoggi was killed. "We're trying to be emotional and at the same time we're trying to get the story - bits and pieces of the story to complete the whole picture". For him, the whole case is "confusing and hard".
British Ambassador Julien Braithwaite told the council his country was "gravely concerned about the deteriorating human rights situation in Saudi Arabia", pointing to women's rights, mass arrests of rights defenders and extensive use of the death penalty.
They were sent to take part in a joint Turkish-Saudi probe, but included experts in chemistry and toxicology who were ordered to clean up any evidence.
As new details continue to emerge about Khashoggi's murder in the Saudi consulate in Istanbul in early October, already hard relations between Turkey and Saudi Arabia have plunged to new lows.
Salah said he was waiting for the investigation to be concluded and for the truth to come out, and believed in Saudi King Salman bin Abdelaziz. "And I have faith in that. This will happen", he said.
Meanwhile, Khashoggi's sons appealed for his remains to be returned so that he may be buried in Saudi Arabia.
"All that we want now is to bury him in Medina with the rest of his family", Salah, 33, said. His brother, Salah, added: "I talked about that with the Saudi authorities and I just hope that it happens soon".
Ankara has also demanded Riyadh cooperate in finding Khashoggi's body, which Istanbul's chief prosecutor said had been dismembered.
Saudi Arabia now draws on its abundant oil and natural-gas resources to meet its fast-growing demand for power and to desalinate its water.
In recent weeks, Saudi nationalists have sought to rally around the prince with adulatory poems and songs on social media as local officials dismiss the Khashoggi crisis as a Western conspiracy.
