U.S. reserves right to sanction MbS -White House

"Of course we reserve the right to take any action at a time and manner of our choosing," Psaki said at a briefing, adding that, "Historically, the United States through Democratic and Republican presidents has not typically sanctioned government leaders of countries where we have diplomatic relations."

A U.N. human rights investigator said on Monday that it was "extremely dangerous" for the United States to have named Saudi Arabia's de facto ruler as having approved an operation to capture or kill journalist Jamal Khashoggi but not to have taken action against him.

Agnes Callamard, special rapporteur on summary executions who led a U.N. investigation into Khashoggi's 2018 murder, reiterated her call for sanctions targeting Crown Prince Mohammed bin Salman's assets and his international engagements.

He approved an operation to capture or kill Khashoggi, according to a declassified U.S. intelligence released on Friday as the United States imposed sanctions on some of those involved but spared the crown prince himself in an effort to preserve relations with the kingdom.
