French President Emmanuel Macron told Saudi Crown Prince Mohammed bin Salman Europeans will insist on international experts being part of the investigations into a Saudi journalist's murder, an Elysee official said on Friday. In a five-minute exchange on the sidelines of the G20 summit in Argentina, Macron conveyed "very firm" messages to the prince over the murder of Khashoggi and on the need to find a political solution for the situation in Yemen, the official added.
