Omar Abdulaziz hit record on his phone and slipped it into the breast pocket of his jacket, he recalled, taking a seat in a Montreal cafe to wait for two men who said they were carrying a personal message from Saudi Crown Prince Mohammed bin Salman. When they arrived, Abdulaziz, a 27-year-old Saudi opposition activist, asked why they had come all the way to Canada to see him. There are two scenarios," one of the emissaries said, speaking of Abdulaziz in the third person. In the first, he can go back home to Saudi Arabia, to his friends and family. In the second: "Omar goes to prison." To drive home what was at stake, the visitors brought one of Abdulaziz's younger brothers from Saudi Arabia to the meeting. The clandestine recordings - more than 10 hours of conversation - were provided to The Washington Post by Abdulaziz, a close associate of the missing Saudi journalist Jamal Khashoggi. They offer a chilling depiction of how Saudi Arabia tries to lure opposition figures back to the kingdom with promises of money and safety. These efforts have sharply escalated since Mohammed became crown prince last year. Khashoggi's friends said that senior Saudi officials close to the crown prince had contacted him in recent months, even offering him a high-level job ... if he returned to the kingdom. He didn't trust the offer, fearing it was a ruse. Khashoggi has not been heard from since he visited the Saudi Consulate in Istanbul on Oct. 2. Turkish investigators have concluded he was killed ... and then dismembered.
