A phone call recording collected by the Turkish intelligence links the brutal murder of Saudi dissident journalist Jamal Khashoggi to the kingdom's Crown Prince Mohammed bin Salman, known as MbS, The New York Times reports.
Turkish President Recep Tayyip Erdogan has repeatedly stated that the killing was ordered by the "highest levels" of the Saudi government.
Erdogan said the culprits were "definitely" among the 18 suspects under arrest in connection with the incident, adding: "It must also be revealed, who gave them the order".
He said Ankara shared evidence linked to the murder with officials from a large number of countries and that France was "no exception".
"We find it unacceptable that he accused President Erdogan of "playing political games", the communications director at the Turkish presidency, Fahrettin Altun, told AFP.

Earlier last month, a Turkish newspaper reported that Khashoggi had received a call from the prince after he was intercepted at the Saudi consulate in Istanbul on October 2.
The Saudis also denied comments allegedly made by the Saudi Crown Prince describing Khashoggi as a risky Islamist.
Khashoggi at the Saudi Consulate there, made the phone call and spoke in Arabic, the people told the NYT.
President Trump has said he believes the Saudis tried to cover up Mr. Khashoggi's killing, but he has reserved judgment on who is to blame until Riyadh provides an official account of the incident, which is expected soon.
Saudi officials characterise the killing as a rogue operation carried out by Saudi agents who exceeded their authority.
Erdoğan said on Friday that Turkey has given recordings "to Saudi Arabia, to America, to the Germans, the French, to the British, to all of them".
