According to Aljabri’s account of alleged plans to assassinate him in Canada, a six-person team landed at Ottawa airport in mid-October 2018, lied to Canadian border officials about knowing one another, and carried suspicious equipment for DNA analysis. The team was deported by Canada after being intercepted by the authorities at the airport. The Canadian government has said: “We are aware of incidents in which foreign actors have attempted to threaten those living in Canada. It is completely unacceptable.”

The serious allegations about Prince Mohammed comes as Saudi Arabia is seeking to improve its image around the world, including through the recent takeover of Newcastle United by the Public Investment Fund, the Saudi-controlled sovereign wealth fund where Prince Mohammed serves as chairman.

In the interview, Aljabri portrayed Prince Mohammed as reckless and untrustworthy.

He is, Aljabri said, “a psychopath with no empathy, [who] doesn’t feel emotion, never learned from his experience.”

The former intelligence chief also claimed that Prince Mohammed “feared” the information Aljabri knew about him, including a 2014 recorded discussion between Prince Mohammed and the then-crown prince Mohammed bin Nayef, in which the present crown prince allegedly said he could kill the sitting king, Abdullah, to clear the throne for his own father, Salman.

“He told him, ‘I want to assassinate King Abdullah. I get a poison ring from Russia. It’s enough for me just to shake hand with him and he will be done.’ … We took it seriously,” Aljabri said.

He added that he knew of two copies of the recording, and that he knew where they were located.

Saudi Arabia has, in turn, accused Aljabri of embezzlement and claimed he stole hundreds of millions of dollars from the kingdom’s own coffers. The allegations were denied by Aljabri and downplayed by Morell, the former acting director of the CIA.

“I don’t know if Dr Saad was corrupt in any way. I wouldn’t be surprised if he wasn’t because he’s such an honorable man. But I also wouldn’t be surprised if he was. Because everybody to some extent had their hand in the kitty. And King Abdullah allowed it, permitted it,” Morell said.
