Meanwhile, Erdoğan discussed the murder of Khashoggi with Canadian Prime Minister Justin Trudeau via telephone on October 26. Salah Khashoggi, a dual Saudi-US citizen, had been barred from leaving Saudi Arabia because of his father's criticism of the country's leadership, but this sanction was recently lifted.
Khashoggi disappeared after entering the Saudi Arabian consulate in Istanbul last month, prompting a Saudi investigation that determined that Khashoggi died in a fistfight inside the building.
In the Saudis' latest version of events, a public prosecutor said the killing was premeditated, reversing an earlier statement that Mr Khashoggi was killed accidentally in a fight at the consulate.
"We are here to demand only one thing from the King and the Crown Prince of the Kingdom of Saudi Arabia: The persons who gave the order for the bestial murder of journalist Jamal Ahmad Khashoggi, and the persons who carried the order, all of them must be brought to account", Nkanga demanded.
President Trump was quick to point fingers at a "rogue" element inside the Saudi government.
But Cengiz said Friday that she would only go to the White House if the administration takes action on Khashoggi's case.
Riyadh on Saturday (Oct 27) dismissed Ankara's calls to extradite 18 Saudis being held over the murder of critic Jamal Khashoggi, as Washington warned the crisis risked destabilising the Middle East.
The ministry referred the extradition request for the suspects - all of whom are Saudi nationals - to Turkish Foreign Ministry, the statement said.
After more than two weeks of global outrage over the journalist and dissident's death, Adel al-Jubeir sought to portray the country as the moral beacon of the Middle East, in stark opposition to Iran, Saudi Arabia's arch-rival.
Erdogan said the dissident journalist was the victim of a carefully planned "political murder" by Saudi intelligence officers and other officials.
Gruesome reports have alleged that he was killed and dismembered by a team sent from Saudi Arabia to silence the Washington Post columnist, who had criticised the kingdom's powerful Crown Prince Mohammed bin Salman. In the past, military exports by Berlin to Saudi have mostly consisted of patrol boats.
In June of a year ago, Saudi Arabia, Egypt, the United Arab Emirates (UAE) and Bahrain collectively severed ties with Doha, accusing it of supporting terrorism. The Saudi monarchy is a creation of the United States and the oil companies.
It took two weeks for Saudi authorities to publicly acknowledge that Khashoggi was dead.
Mr Al Jubeir said he has no concern about the future of the region as "light always triumphs over darkness", and therefore he said he believes the Middle East "will end up in a better place, a more prosperous, more peaceful place".
He repeatedly reassured Khashoggi, say multiple sources, he had nothing to fear by going back home.
Speaking at the security forum, the Saudi foreign minister opened by painting a bleak modern history of the region pointing to conflicts and war in the past five decades that led to the rise of terror groups and civil conflict.
