Jubeir didn't directly answer a question about whether it was credible for the Saudi leadership to suggest Crown Prince Mohammed bin Salman would have been unaware of a large-scale operation involving more than a dozen agents to target Khashoggi in Istanbul.
"From the person who gave the order to the person who carried it out, they must all be brought to account".
Speaking with Turkish television network Haberturk in her first interview since Khashoggi's death, Hatice Cengiz said she "died every day" since Khashoggi was killed by Saudi officials inside the country's consulate in Istanbul, Turkey.
Mr Khashoggi was killed on 2 October at the Saudi Consulate in Istanbul.
Erdogan said he had spoken with Prince Mohammed. "We know that a mistake was committed", al-Jubeir said Saturday.
The minister also said the administration of US President Donald Trump has a "rational, realistic" foreign policy that all Gulf Arab states can support.
There's a lot of money in Saudi Arabia, so much money, so wrestling is going back to Saudi Arabia as we wonder whether Saudi Arabia kills journalists with bone saws.
"I found myself in a darkness I can not express", Ms Cengiz said of the pain she had felt since his disappearance.
The killing of journalist Jamal Khashoggi "undermines regional stability" and the US State Department plans to take further action in response to the killing, US Defense Secretary Jim Mattis said Saturday at an global conference in the Middle East.
"We intend to consult with Congress and to work with other nations to hold accountable those responsible for the killing of Jamal Khashoggi", said Palladino.
German Chancellor Angela Merkel vowed on Friday that Berlin would not export arms to Saudi Arabia until the murder is clarified, a stance French President Emmanuel Macron dubbed "pure demagoguery" as it "has nothing to do with Mr Khashoggi". 'He thought Turkey is a safe country and if he would be held or interrogated, this issue would be swiftly solved'.
Al-Jubeir said critics should wait for the Saudi investigation to publish its conclusions rather than blaming the kingdom "from the get-go".
The kingdom's chief prosecutor said Thursday that the murder was premeditated.
In his first public comments on the case, Prince Mohammed, the kingdom's de factor ruler, this week denounced the "repulsive" murder for which 18 Saudis including a senior intelligence officer have been detained.
