According to the official Anadolu news agency, Istanbul prosecutors are seeking life imprisonment for two of the suspects and up to five years in jail for the remaining four.
The Washington Post contributor, Khashoggi, 59, was killed and dismembered at the kingdom’s consulate in Istanbul on October 2, 2018, in a case that tarnished the reputation of Crown Prince Mohammed bin Salman.
Khashoggi went inside the consulate to obtain paperwork for his marriage to Turkish fiancee Hatice Cengiz.
The six Saudi suspects, indicted just days ahead of the second anniversary of the journalist’s death, are not in Turkey and should be tried in absentia.
In a separate case launched in July, an Istanbul court began to try in absentia 20 other Saudis over the murder, including two former aides to the Saudi prince.
Turkish prosecutors claim Saudi deputy intelligence chief Ahmed al-Assiri and the royal court’s media czar Saud al-Qahtani led the operation and gave orders to a Saudi hit team.
Khashoggi was strangled and his body cut into pieces by a 15-man Saudi squad inside the consulate, according to Turkish officials.
His remains have not been found.
Turkish President Recep Tayyip Erdogan has said the order to murder Khashoggi came from “the highest levels” of the Saudi government but has never directly blamed Prince Mohammed.
In September, a Saudi court overturned five death sentences issued after a closed-door trial in Saudi Arabia that ended last year, sentencing them to 20 years in prison instead.
