ISIS tunnel network found in Syria’s al-Bab
Erdogan stressed that they are on the verge of controlling the ISIS held city
A video recorded by Turkish troops and special forces backed by the Free Syria Army involved in operation "Euphrates Shield” revealed the existence of tunnels in the Syrian city al-Bab used by ISIS militants.
Turkish president Recep Tayyip Erdogan announced on Monday that Turkish forces and factions of the Free Syrian Army have reached the center of the city in northern Syria, stressing that they are on the verge of controlling the ISIS held city in the country side of northern Aleppo.
There seems to be a rivalry between the Euphrates Shield forces and the regime to control the strategic city.
