At least 21 ISIL terrorists were “neutralized” in northern Syria in the last 24 hours as part of the ongoing Operation Euphrates Shield, according to a Turkish General Staff statement released on Saturday.

Also, 156 ISIL targets, including the terror group’s shelters, headquarters, defense positions and vehicles had been hit by Free Syrian Army (FSA) fighters with Turkish army’s support during the same time period, the statement said.

Turkish Air force also hit 12 ISIL targets in Syria’s Al-Bab, Suflaniyyah and Kabr al Mukri regions, including control points, shelters, headquarters and vehicles used by the terrorists, the statement added.

The Turkish army is supporting FSA fighters in liberating Al-Bab, a strategic city for ISIL, from the terrorist group. Saturday marks the 137th day since the city was surrounded in order to liberate it.

The statement also said 43 mines and 2,794 improvised explosives had been defused since the start of the operation on Aug. 24.

The Turkey-led Operation Euphrates Shield began in late August to improve security, support coalition forces, and eliminate the terror threat along the Turkish border using FSA fighters backed by Turkish artillery and jets.
