After journalist Jamal Khashoggi entered Saudi Arabia's consulate in Istanbul on Oct. 2, he was seized by 15 Saudi agents, and endured verbal abuse by Saud al-Qahtani via Skype, people with knowledge of the matter told Reuters on Monday. Qahtani was one of Crown Prince Mohammed bin Salman's top aides, and after insulting Khashoggi, he ordered the Saudi agents "bring me the head of the dog," a Turkish intelligence source told Reuters. It is not clear if he watched as Khashoggi was murdered. Saudi Arabia has said Khashoggi was killed in a "rogue operation," which the crown prince knew nothing about, and his death was an accident. Turkish officials said he was murdered. People with knowledge of the matter said Qahtani has been chosen as one of the fall guys to protect the crown prince.
