German Chancellor Angela Merkel said on Sunday that Germany would put arms exports to the kingdom on hold for the time being, given the unexplained circumstances of dissident journalist Jamal Khashoggi's death.
Mr Khashoggi, a prominent journalist and royal court insider for decades in Saudi Arabia, had written columns critical of Crown Prince Mohammed bin Salman and the kingdom's direction while living in self-imposed exile in the US.
Jubeir insisted, however, that the operation was not ordered by Crown Prince Mohammed bin Salman, despite reports tying some suspects to members of the de facto ruler's security detail.
"We can feel their pain and we wish this didn't happen and I wish that this could have been avoided", he said.
Adel al-Jubeir told Fox News on Sunday that those responsible will be held accountable for "this huge and grave mistake".
U.S. Treasury Secretary Stephen Mnuchin said Saudi Arabia's admission that the Washington Post columnist was killed in a fistfight was a "good first step but not enough", though he added it was premature to discuss sanctions against Riyadh.
Saudi state media initially claimed that Khashoggi left the Saudi consulate in Istanbul alive, while Turkish officials claimed early on that Khashoggi had been killed.
Turkey's foreign minister says his country has not shared any audio recordings from Saudi journalist Jamal Khashoggi's disappearance with USA officials.
Speaking during an exclusive interview with Fox News' Bret Baier, Saudi Foreign Minister Adel Al-Jubeir said that the country is now investigating Khashoggi's death and that the 18 people implicated in his slaying would be punished appropriately.
Foreign Affairs Minister Chrystia Freeland said in a statement Saturday night that the Saudis' "explanations" of the killing of Khashoggi "lack consistency and credibility".
The official told The Associated Press on Friday that police have established that two vehicles belonging to the Saudi consulate left the building on October 2 - the day Khashoggi had walked into the consulate and vanished.
Kushner, who had cultivated a close personal relationship with the crown prince, commonly known as MbS, urged Trump to act with caution to avoid upsetting a critical strategic and economic relationship, a senior administration official said.
For Saudi Arabia's allies, the question will be whether they believe that the Crown Prince, who has painted himself as a reformer, has any culpability.
Donald Trump has found credible explanations for saudi arabia, but said that they were too short.
Sen. Lindsey Graham, R-S.C., tweeted on Friday, "To say that I am skeptical of the new Saudi narrative about Mr. Khashoggi is an understatement".
In response to the comments by the Kentucky senator, Mr Jubeir said he finds it "very surprising that somebody 6,000 miles away can be certain about an event that happened 6,000 miles away with no access to information or intelligence".
U.N. Secretary General Antonio Guterres, the European Union and numerous European officials condemned Khashoggi's killing and called for a thorough and transparent investigation, with accountability for those involved.
He said the government supported an investigation into the killing.
"I think everything should be on the table", Sasse said. "But I want to get to the answer", Trump told reporters this weekend, when asked about the Saudi investigation and Riyadh's firing of officials.
The White House is acknowledging the announcement from Saudi Arabia that journalist Jamal Khashoggi is dead and that 18 Saudi nationals are in custody on suspicion of involvement in his death. "We feel their pain", Jubeir said in the interview.
A bipartisan group of US lawmakers are accusing the crown prince of directing the operation.
