MOSCOW - Russian President Vladimir Putin told his US counterpart Donald Trump on Tuesday of his meeting with Syrian President Bashar Assad, stressing the importance of finding a political solution to the civil war. Two men spoke by telephone for about an hour, covering topics including Syria, Ukraine, Iran, North Korea and Afghanistan, a White House official said earlier. 'The message was sent of the necessity to keep the sovereignty, independence and territorial integrity of Syria and to reach a political settlement based on principals to be worked out in a full-scale negotiation process in Syria,' the Kremlin said.
