Tubaigy began to cut Khashoggi’s body up on a table in the study while he was still alive, the Turkish source said. The killing took seven minutes, the source said.

As he started to dismember the body, Tubaigy put on earphones and listened to music. He advised other members of the squad to do the same.

"When I do this job, I listen to music. You should do [that] too," Tubaigy was recorded as saying, the source told MEE.
