TOPSHOT - This picture taken on March 15, 2020 shows an aerial view of Syrians protesting and setting tyres aflame in an attempt to block traffic on the M4 highway, which links the northern Syrian provinces of Aleppo and Latakia, before incoming joint Turkish and Russian military patrols (as per an earlier agreed upon ceasefire deal) in the village of al-Nayrab, about 14 kilometres southeast of the city of Idlib and seven kilometres west of Saraqib in northwestern Syria. - Russian President Vladimir Putin and his Turkish counterpart Recep Tayyip Erdogan reached a deal on March 5 to create a security corridor with joint Turkish and Russian patrols starting on March 15 along the key M4 highway in northern Syria, which runs roughly parallel to the border with Turkey, from northeastern Kurdish-controlled regions to the Mediterranean coast.
