US Secretary of State Michael Pompeo said he expects Turkish and Saudi Arabian investigations to reveal a "complete picture" of what happened to journalist Jamal Khashoggi, as the Trump administration comes under increasing pressure to respond to the incident.
During Pompeo's visit, Turkish President Recep Tayyip Erdogan assured him that they would share the results from their investigation with the Saudis as well.
Turkish officials have said they believe he was killed there although this has not been confirmed by Saudi Arabia.
Khashoggi worked as an opinion columnist at The Washington Post newspaper, and has written critically of the Saudi government and its crown prince, Mohammad Bin Salman.
France doesn't, however, appear to be making any changes to its arms deals with Saudi Arabia.
"Unless the miracle of all miracles happens, I would acknowledge that he's dead", Trump said to The Times.
"We're working with the intelligence from numerous countries", he said. "This is the best intelligence we could have". Turkish officials allege he was murdered there.More news: Rihanna Turned Down Super Bowl LIII Halftime Show to Support Kaepernick
"I think it's important for us all to remember, too - we have a long, since 1932, a long strategic relationship with the Kingdom of Saudi Arabia", Pompeo told reporters, also calling Saudi Arabia "an important counterterrorism partner".
Turkish authorities say he was killed by a special team of 15 Saudi officials that flew into Istanbul and left the day Khashoggi arrived at the consulate.
Meanwhile, Trump has touted the strategic alliance between the USA and Saudi Arabia, boasting about billions of dollars in planned arms sales to the Saudis.
The area became a target of the investigation after police focused on the vehicles which had left the consulate on the day Khashoggi disappeared, NTV channel reported.
There is a perception here among critics of the Trump administration that United States officials are working with the Saudis to give them time to come up with a "cover story".

In a related development, the Committee to Protect Journalists, Human Rights Watch, Amnesty International, and Reporters Without Borders on Thursday urged Turkey to urgently ask UN Secretary-General Antonio Guterres to establish a UN investigation into the possible extrajudicial execution of Khashoggi.
