These latest revelations from anonymous Turkish officials as well as Turkey's president come just hours after Pompeo finished an all-smiles meeting with the Saudi crown prince and King Salman, during which-according to State Department spokesperson Heather Nauert-the US secretary of state "thanked the King for Saudi Arabia's strong partnership with the United States" and applauded the murderous regime for vowing to carry out "a thorough, transparent, and timely investigation of Jamal Khashoggi's disappearance".
A Saudi contribution of $100 million to US -backed stabilization efforts in Syria arrived in American accounts Tuesday, just as State Mike Pompeo touched down in Riyadh to discuss the missing Saudi journalist, an anonymous USA official told The New York Times.
Turkey hopes to enter the Saudi consul's residence in Istanbul on Wednesday in connection with the disappearance of Saudi journalist Jamal Khashoggi, Turkey's foreign minister said after meeting U.S. Secretary of State Mike Pompeo.
The Wall Street Journal, citing a Turkish official who has heard the recording, said Mr Khashoggi was allegedly killed and dismembered in the office of the Saudi consul general, Mohammad al-Otaibi, who was in the room at the time.
CNN said the Saudis may argue the operation was conducted without clearance and those responsible would be held accountable. "The Saudis claimed that the consul's family was inside", Mevlut Cavusoglu told reporters after meeting Pompeo.
TRT World's Francis Collings has more from outside the Saudi consulate in Istanbul.
Other business leaders who have said they would not attend the conference, including Uber Chief Executive Dara Khosrowshahi, said they were concerned about Khashoggi's disappearance. Trump has resisted any action, pointing to huge USA weapons deals pending with Saudi Arabia and saying that sanctions could end up hurting the American economy.
Jamal Khashoggi, 60, is feared to have been killed inside the Saudi consulate in Istanbul.
"Government welcomes the ongoing diplomatic interaction between the Republic of Turkey and the Kingdom of Saudi Arabia, as well as the investigation which seeks to get to the bottom of this matter", Mabaya said.
The US president gave no evidence to support the theory.
This may explain in part Mr Trump's "rogue killers" line, though it would still leave questions unanswered.
"Absolutely extraordinary they were able to enlist the President of the United States as their PR agent to float it".
Asked whether they said Khashoggi was alive or dead, Pompeo said: "They didn't talk about any of the facts".
Sen. Lindsey Graham, R-S.C., said the United States should "sanction the hell out of Saudi Arabia" and slammed the crown prince, known by his initials MBS, as a "toxic" figure.
The consulate itself, where Mr Khashoggi was last seen on 2 October, was searched by Turkish investigators on Monday for the first time.
A Saudi official, not authorized to speak publicly, told Reuters that the king had ordered an internal investigation based on information from the joint team in Istanbul. Khashoggi had fled the country a year ago amid the rise of Prince Mohammed, whom he wrote critically about in the Post.
Riyadh insists that the journalist left the consulate safely.
