Saudi Crown Prince Mohammed bin Salman says he bears responsibility for the murder of Washington Post columnist Jamal Khashoggi because “It happened under my watch.” in an excerpted interview from an upcoming documentary series.

"It happened under my watch," the Saudi leader told PBS FRONTLINE correspondent Martin Smith on the sidelines of an electric car race near Riyadh, Saudi Arabia. “I get all the responsibility, because it happened under my watch.”

He insisted, though, that he had no involvement or knowledge in the killing.

"We have 20 million people. We have 3 million government employees," he replied, when asked how the murder could have happened without his knowledge.

When pressed further, and asked how the killers could have used Saudi planes to fly between Saudi Arabia and Turkey to commit the murder, Prince Mohammed said, "I have officials, ministers to follow things, and they’re responsible, they have the authority to do that."
