AFRIN, Syria: The Turkish military on Thursday discovered a 30-meter tunnel and a concrete factory during a security sweep in Syria’s Afrin region, recently liberated from YPG/PKK .
During a search, security forces found a concrete plant used to build tunnels and fortifications in Afrin.
The military also found tunnels and buildings made by the plant.
Turkey launched Operation Olive Branch on Jan. 20 to clear rebels groups from Afrin, northwestern Syria amid growing threats from the region.
On March 18, Turkish-backed troops liberated the town center of Afrin, which had been a major hideout for the YPG/PKK since 2012.
Afterwards, the Turkish military began security sweeps for mines, improvised explosive devices, and rebels hideouts to wipe out any traces of clashes so residents can resume their normal lives.
