These are the 15 Saudis suspected in the disappearance and alleged killing of journalist Jamal Khashoggi

Turkish officials released still images from surveillance cameras last week of the 15 Saudi nationals they say are suspects in the disappearance, and alleged murder, of journalist Jamal Khashoggi. 

Khashoggi, who was often critical of the Saudi government and Crown Prince Mohammed bin Salman, was last seen entering the Saudi consulate in Istanbul on October 2. 

Turkish officials have alleged that Crown Prince Mohammed's government sent a team of 15 men to Istanbul to kill Khashoggi at the consulate, though Saudi Arabia is reportedly preparing a report claiming Khashoggi was inadvertently killed during a botched interrogation.

Turkish investigators, who say they have listened to audio recordings from inside the consulate, reportedly believe that Khashoggi was beaten, tortured, killed, and dismembered after entering the building.

The 15 Saudi suspects all flew into Istanbul on the day Khashoggi disappeared, according to Turkey's Daily Sabah, which first published photos of the suspects. 

Here's what we know about them, based on a Washington Post investigation and reports from Turkish, Saudi and US media reports.
