An adviser to Turkey's president, meanwhile, said Prince Mohammed had "blood on his hands" over Mr Khashoggi, the bluntest language yet from someone linked to Recep Tayyip Erdogan about the de facto ruler of the kingdom in connection with the death.
The fallout has damaged Saudi Arabia, badly tarnished Crown Prince Mohammed bin Salman and raised questions about United States foreign policy priorities that hinge on the kingdom's financing or cooperation.
The Saudis have presented shifting stories about Khashoggi's fate, initially denying any knowledge before arguing that a group of rogue operators, many of whom belong to the crown prince's inner circle, were responsible for Khashoggi's death. "He's running things and so if anybody were going to be, it would be him".
Prince Mohammed told a major investment conference in Riyadh that the killers of Jamal Khashoggi would be brought to justice, in his first public comments since the journalist's murder sparked global condemnation.
She told MPs: "We condemn the killing of the journalist Jamal Khashoggi in the strongest possible terms and after his disappearance we made clear that Saudi Arabia must co-operate with Turkey and conduct a full and credible investigation".

Inman said she contacted the Garland County Election Commission. "Just get out and vote", said student voter Terrence Johnson. Virginia's record for absentee voting in any race was set in 2008, when 506,672 people voted early.
Last week, the Turkish government denied giving "any kind of audio tape" from the investigation to any United States official.
Meanwhile, the Turkish President has not confirmed if a recording of Khashoggi's murder and alleged torture exists. Mohammed has also tried to lure exiled dissidents like Khashoggi, who lived in Virginia, back to Saudi Arabia, Khashoggi's friends and other exiles said.
In deciding what action to take, he said, the Government also needs to take account of the important stabilising role which Saudi Arabia has played in the Middle East.
CIA Director Gina Haspel visited Ankara on Tuesday for talks, with Turkish pro-government media claiming on Wednesday intelligence officials shared evidence with her.
After denying Khashoggi's death for almost three weeks, the kingdom last week said the columnist was accidentally killed after a discussion at the consulate turned into an altercation.
The leaks also seemed meant to whip up a sense of anticipation ahead of the speech by Erdogan, who has chided the Saudis in recent weeks for not cooperating with the Turkish investigation but stopped short of blaming the Saudi government for Khashoggi's death.
He also confirmed that a body double for Khashoggi had been deployed by Saudi Arabia.
A joint Turkish-Saudi team completed an investigation into the case on Thursday after searching the residence of the consul general as well as the Saudi consulate in Istanbul.
