Sputnik Arabia’s sources have reported that militants from the group Hayat Tahrir al-Sham are digging a tunnel network throughout the province as a part of their preparations for battle against the Syrian army. Locals told Sputnik that the group had forced thousands of captives to dig the tunnels both with and without special equipment. The sources also said that some of the tunnels were so wide that a car could drive through them.
