A banner bearing the Turkish flag and a picture of Turkish President Recep Tayyip Erdogan is seen hanging from a building while Syrians wave rebel flags during a demonstration below in the rebel-held town of Azaz in northern Syria on January 19, 2018, in support of a joint rebel and Turkish military operation against Syrian-Kurdish forces in Afrin. In recent days Turkish forces have been shelling the YPG enclave of Afrin as Turkey had announced its intentions to launch an operation to oust the group from the town and has massed troops and armour on the border.
