French President Emmanuel Macron said he will have a talk with Saudi Arabia Crown Prince Mohammed Bin Salman on the sidelines of the Group of 20 meeting in Argentina and reiterated his call for a full probe of the death of Jamal Khashoggi, a critic of the kingdom.

"I have always been very clear about the Saudi Arabia case — and I will surely have the occasion to discuss this with the Crown Prince on the sidelines of the ... ," Macron said during a joint press conference with his Argentinian counterpart, Mauricio Macri, in Buenos Aires. "The death of Mr. Khashoggi is a serious matter on which I want the entire truth to be made," he said.

The crown prince's appearance at G-20 comes amid an outcry over Khashoggi's killing and the summit will gauge how willing world leaders are to be associated with him following Khashoggi's murder at the Saudi Consulate in Istanbul last month. Canada joined the U.S. on Thursday in sanctioning Saudi officials, including the crown prince, in connection with the murder.
