Saudi Arabia's Crown Prince Mohammed bin Salman, left, and Russia's President Vladimir Putin speak at the start of the G20 summit in Buenos Aires, Argentina, Friday, Nov. 30, 2018.
– The G-20 summit is underway in Argentina, and the greeting between two high-profile leaders is drawing attention for its, er, enthusiasm. This time, it doesn't involve President Trump, but Russia's Vladimir Putin and Saudi crown prince Mohammed bin Salman. It's not so much a handshake as a high-five, accompanied by beaming smiles. The prince even pats Putin's hand three times as they take their seats, notes the AP. Watch it here. (Putin has been in the headlines of late over his nation's seizure of Ukrainian ships, and the crown prince because of the Jamal Khashoggi killing.)
