Kuweires, an outpost previously besieged by Daesh and liberated in November 2015, is set to become the springboard for the offensive.
The Turkish military, Turkish-back Free Syrian Army (FSA) forces, the Kurdish Rojava forces and the Syrian army are all currently converging on Daesh-held al-Bab.
On August 24, 2016, the Turkish army launched Operation Euphrates Shield against Daesh militants. Turkish forces, with assistance from Syrian opposition fighters, occupied the city of Jarabulus in northern Syria and are currently conducting an offensive on al-Bab. Turkish President Recep Tayyip Erdogan has said that the aim of the operation is to clear the region of terrorists and make it a safety zone for refugees.
The operation has been widely criticized both by the Syrian Kurds and Damascus, who have accused Ankara of violating Syria's territorial integrity.
