TOPSHOT - Syrian refugees are pictured in a camp as Syrians fleeing the northern embattled city of Aleppo wait on February 6, 2016 in Bab al-Salama, near the city of Azaz, northern Syria, near the Turkish border crossing.
Turkey on Saturday said it was expecting a huge wave of Syrians fleeing a government onslaught on rebel-held territory, with a regional governor saying at least 70,000 people may be heading for the border. The United Nations said some 20,000 people had gathered at Syria's Bab al-Salam crossing with Turkey. An AFP reporter said the crossing was closed but the Syrian side of it was being supplied by aid trucks coming from Turkey.
