Yalova Governor Muammer Erol said that the Istanbul Chief Public Prosecutor’s Office will make a final statement about the search operation.
Sniffer dogs and drones backed the operation.
Khashoggi, a journalist and columnist for The Washington Post, went missing after entering the Saudi Consulate in Istanbul on 2 October.
After initially saying he had left the consulate alive, weeks later the Saudi administration admitted he was killed there, blaming a rogue group of Saudi operatives.
