DEIR AL ZOR, SYRIA - MARCH 23: Syrian Democratic Force's commander in chief Mazloum Kobani, (2nd-L) shakes hands with William Robak, advisor for the US Department of State in northern Syria (2nd-R) after unveiling a victory monument during a SDF victory ceremony announcing the defeat of ISIL in Baghouz held at Omer Oil Field on March 23, 2019 in Deir Al Zor, Syria. The Kurdish-led and American-backed Syrian Defense Forces (SDF) declared on Saturday the "100% territorial defeat" of the so-called Islamic State, also known as ISIS or ISIL. The group once controlled vast areas across Syria and Iraq and a population of up to 12 million, an aspired "caliphate" that drew tens of thousands of foreign nationals to join its ranks.
