Meanwhile, Turkey’s military has encircled the northern Syrian city of Afrin, where the United Nations is warning of a growing humanitarian disaster. Residents of Afrin have had no access to clean drinking water for a week, after Turkish troops and their allies cut water supplies to the area. Turkish President Recep Tayyip Erdogan has vowed to crush the Kurdish YPG militia, known as the People’s Protection Units, who control Afrin. Turkey’s offensive has sparked protests by Kurds around the world. On Tuesday, police in Paris used tear gas to drive back hundreds of Kurdish protesters and their allies as they demonstrated outside the U.S. Embassy, where they accused the Trump administration of failing to prevent Turkish atrocities in Syria.
