Istanbul, Turkey (CNN) Recordings related to Saudi journalist Jamal Khashoggi's death have been passed on to Saudi Arabia, the United States, the United Kingdom, Germany and France, Turkey's President Recep Tayyip Erdogan said Saturday.

Khashoggi was killed after he entered the Saudi consulate in Istanbul on October 2 to obtain paperwork for his marriage.

Speaking before his departure to Paris for World War I commemorations, Erdogan said: "We passed on the recordings. We gave them to Saudi Arabia, to America, to the Germans, French and the English -- we gave them all."

He did not elaborate on what was on the recordings.

US President Donald Trump and Turkish President Recep Tayyip Erdogan sat next to each other at the dinner hosted by French President Emmanuel Macron Saturday evening in Paris.

Erdogan said the killer, or killers, would be known to the 18 suspects identified by Turkish authorities -- including 15 men who arrived from Saudi Arabia shortly before Khashoggi's death.
