The State Department on Monday barred 16 Saudi nationals from entering the US for their role in the murder of journalist Jamal Khashoggi, a former columnist for the Washington Post.

The State Department ruled the individuals — including Saud al-Qahtani, a close aide to Crown Prince Mohammed bin Salman — had been involved in “significant corruption or gross violations of human rights.”

Maher Mutreb, who the New York Times previously described as a security agent on the crown prince’s security detail, was also included on the list.

The crown prince himself, who has been described as “responsible” for Khashoggi’s death in a resolution passed by the US Senate, was not included on the list.

The announcement by Secretary of State Mike Pompeo comes as the Trump administration has faced harsh scrutiny from Congress because he has not admonished Saudi Arabia for Khashoggi’s killing.

Trump has not publicly said the crown prince bears any responsibility for Khashoggi’s death.

Khashoggi, a US national who was critical of Saudi Arabia in his columns, was killed and dismembered in the Saudi consulate in Turkey last October. His body has not been found.

Saudi Arabia at first denied involvement in the killing, but later said the slaying was carried out by rogue agents from the country.
