Since refusing to return home to Saudi Arabia, activist Omar Abdulaziz says the government has gone after his family and friends.

In the Khashoggi killing, Saud al-Qahtani was present as he has been in other key moments of Crown Prince Mohamed bin Salman's administration. This time, though, his presence was virtual.

If Prince Mohammed bin Salman ascends the throne, he could be in power for decades, longer than any other royal since Saudi Arabia's founding in 1932.
