Turkish officials appear to have dismissed a theory that Jamal Khashoggi's body was given to a mystery local collaborator in Istanbul. "We are going to hold accountable not only those who executed the murder but also those who led, involved or were connected to it", Palladino said.
It is also pressing Saudi Arabia for information concerning Khashoggi's remains, which still haven't been found, as well as who ordered the journalist's slaying.
Khashoggi, a USA resident and columnist for The Washington Post, was last seen entering the Saudi consulate in Istanbul on October 2.
The US will need a "handful more weeks" to decide if Saudi Arabia should be somehow sanctioned for the murder of Jamal Khashoggi, Mike Pompeo has said, noting that Riyadh remains a "great partner" serving US national security.
The Bill & Melinda Gates Foundation have made a decision to cancel most of its $5 million charity to Saudi following Jamal Khashoggi's murder. That was seven days after the dissident disappeared in the Saudi Consulate in Istanbul and long before the crown prince acknowledged that Saudi agents killed him. Imagine what would happen if Saudi Arabia were destabilized.
Israeli officials confirmed the Post's report to the Ynet news site, saying Netanyahu urged officials in Washington not to allow the close relationship with the Saudi crown prince to be undermined by the incident.
The Saudi crown prince called Jamal Khashoggi a unsafe Islamist during a phone call with Jared Kushner and national security adviser John Bolton days after the journalist disappeared last month at the Saudi consulate in Turkey, according to a report on Thursday.
Mr Khashoggi's family vehemently denied that he was in any way risky or a member of the Muslim Brotherhood. "He denied such claims repeatedly over the past several years", the family said.
Turkey, for its part, said Khashoggi was strangled the moment he entered the Saudi consulate in Istanbul, the city's chief prosecutor said on Wednesday, adding that it was a premeditated murder.
"We don't know where the body is", he said.
After Saudi Arabia admitted that Khashoggi was killed in its Istanbul consulate, five high-ranking officials were dismissed, including bin Salman's media chief and the deputy head of the Saudi intelligence service.
President Trump has said he is "not satisfied" with the Saudi account.
United States activists have launched a petition, calling for a section of road near the Saudi embassy in Washington to be renamed Jamal Khashoggi Way.
