US President Donald Trump and Saudi Arabian King Salman bin Abd Al-Aziz “agreed to support safe zones in Syria” in a phone call on Sunday, the White House said, marking a potentially dramatic shift in Washington’s posture toward the civil war there. The White House cast Trump’s support for safe zones in Syria as just one of many policy ideas that will “help the many refugees who are displaced” from the war, which has prompted the worst refugee crisis since World War II.
