The killing of Jamal Khashoggi caused outrage throughout the world.
The indictment in Turkey accuses the suspects - including Saudi Arabia's former deputy intelligence chief - of plotting the murder and assembling a squad to carry it out.
However, much to the dismay of Turkish prosecutors, none of the accused were present in the courtroom because the Saudi government has repeatedly turned down extradition requests.
Khashoggi was a vocal critic of Crown Prince Mohammed bin Salman.
He was murdered by a team of Saudi agents inside the kingdom's consulate in the Turkish city of Istanbul in 2018.
The defendants include two former aides to the prince – both deny involvement.
Last year, Saudi Arabia convicted eight people over the murder. Five were sentenced to death, while three others were handed prison sentences for covering up the crime.
However, the UN described the Saudi trial as "the antithesis of justice".
The trial in Turkey has been adjourned until 24 November.
