President Donald Trump declared this morning the US will uncover the truth about what happened to journalist and US resident Jamal Khashoggi, whose possible murder at Saudi hands after disappearing in Istanbul has captured worldwide attention.
Trump promised to personally call Saudi Arabia's King Salman soon about "the terrible situation in Turkey."
"We're going to find out what happened," Trump pledged when questioned by reporters in Cincinnati where he was headlining a political rally.
Khashoggi, a forceful critic of the Saudi government, went missing more than a week ago after entering a Saudi consulate in Istanbul, and Turkish officials have said they believe he was murdered there.
It comes as Turkey's government has told US officials it has audio and video proof that missing Saudi Arabian writer Jamal Khashoggi was killed and dismembered in the Saudi consulate in Istanbul, the Washington Post reported overnight.
The newspaper, for which Khashoggi is a columnist, cited anonymous officials as saying the recordings show a Saudi security team detained the writer when he went to the consulate on October 2 to pick up a document for his upcoming wedding.
The Associated Press was not immediately able to confirm the report and Turkish officials would not comment.
Meanwhile, a delegation from Saudi Arabia arrived in Turkey this morning as part of an investigation into the writer's disappearance, a Foreign Ministry official said.
Saudi Arabia has called the allegation it abducted or harmed Khashoggi "baseless." However, it has offered no evidence to support its claim he left the consulate and vanished, despite his fiancee waiting outside.
Turkey's state-run Anadolu Agency said the delegation would hold talks with Turkish officials over the weekend. It did not provide further details.
On Friday, Turkish presidential spokesman Ibrahim Kalin said Turkey and Saudi Arabia would form a "joint working group" to look into Khashoggi's disappearance.
In a statement posted on Twitter, Saudi Arabia welcomed Turkey's approval of the joint working group. The Saudi statement said the kingdom is keen "to sustain the security and safety of its citizenry, wherever they might happen to be."
Amid growing concern over Khashoggi's fate, French President Emmanuel Macron said country wanted to know "the whole truth" about the writer's disappearance, calling the early details about the case "very worrying."
Macron said "I'm waiting for the truth and complete clarity to be made" since the matter is "very serious." He spoke Friday in Yerevan, Armenia, to French broadcasters RFI and France 24.
In Germany, Chancellor Angela Merkel's spokesman, Steffen Seibert, said Berlin was also "very concerned" about the writer's disappearance and called on Saudi Arabia to "participate fully" in clearing up reports that he may have been killed.
