UPDATE 1-Saudi Crown Prince stands at far edge during G20 official photo of leaders
Saudi Arabia's Crown Prince Mohammed bin Salman was sidelined during the official "family photo" of world leaders and other dignitaries at the Group of 20 summits in Buenos Aires on Friday, standing at the far edge of the group portrait and ignored.
The crown prince, Saudi Arabia's de facto ruler, quickly exited the stage without shaking hands or talking with other leaders.
At centre stage was Argentine President Mauricio Macri, hosting this year's summit of G20 industrialized nations.
Macri has said accusations that Prince Mohammed was involved in Khashoggi's death could be discussed by world leaders during the two-day summit. Saudi Arabia has said the prince had no prior knowledge of the murder.
Russian President Vladimir Putin and Prince Mohammed later exchanged a high-five and a handshake and laughed heartily as they took seats next to each other in the main meeting room.
