Saudi Arabia's public prosecutor on Saturday said 18 people were arrested in connection with the incident. He changed his tone once again late this week, raising the prospect of sanctions against Riyadh.
Erdogan spoke after Saudi Arabia, in a statement early Saturday, finally acknowledged that 59-year-old Khashoggi had died in the consulate, though its explanation that he was killed in a "fistfight" was met with worldwide skepticism and allegations of a cover-up created to absolve Prince Mohammed of direct responsibility.
The evolving explanation comes 19 days after Khashoggi, a Saudi journalist who had been critical of his country's current government, disappeared on October 2 after going into the Saudi consulate in Istanbul.
Turkish media outlets have reported that the authorities here have audio tapes in which Khashoggi's alleged killers tortured him by cutting his fingers off before his decapitation.
It comes as Germany's foreign minister called into question the sale of arms to Saudi Arabia.
The chief executive of Japan's biggest bank has pulled out of Saudi Arabia's financial conference dubbed "Davos in the Desert", joining a growing list of withdrawals following the killing of a government critic at the kingdom's consulate in Turkey. "However we want punishments not only for the 18 men, but also for the authorities that gave the orders".

"First we were told Mr Khashoggi supposedly left the consulate and there was blanket denial of any Saudi involvement", Mr Graham tweeted on Friday. "We feel their pain", Jubeir said in the interview. Two weeks after Khashoggi's disappearance, he posted a tweet apparently responding to widespread accusations that he was the mastermind of Khashoggi's killing.
Responding to a question, the USA president indicated that he would let the Congressmen take lead on the issue of particularly determining the action that needs to be taken against Saudi Arabia.
The Saudi government initially denied the allegation, but finally admitted early Saturday that Khashoggi had died at the consulate, claiming he was killed in a fistfight.
"People fear them. You challenge them, you might end up in prison, and that has happened", he said. The Saudi statements on Saturday did not address what happened to the body.
On Capitol Hill, politicians including Trump ally Senator Lindsey Graham expressed scepticism about the Saudi account, which was vastly different from that given by Turkish officials, who said an "assassination squad" sent by the kingdom had killed and dismembered Mr Khashoggi. "They made the mistake when they killed Jamal Khashoggi in the consulate and they tried to cover up for it". But the prince himself, protected by his 82-year-old father, King Salman, has been tapped to lead a panel to reform the kingdom's intelligence services, a sign he will remain next in line to the throne. Saudi Arabia ranked sixth previous year with approved sales of 254 million euros ($292 million), mostly reflecting deliveries of patrol boats, according to a government report published in June.
