Turkish airstrikes and shelling have killed 15 Daesh terrorists as part of the operation to liberate the northern Syrian town of al-Bab from terrorists, the military said on Thursday.

A total of 258 identified targets were shelled by the Turkish military, including some shelters, possible defense positions, and tunnel entries used by Daesh terrorists.

Turkish warplanes also hit 20 Daesh targets, destroying 15 buildings used as shelters, two headquarters, two arsenals and one bomb laden vehicle belonging to the terrorist organization.

The Turkish military continues to take all necessary measures to ensure the safety of civilians in the area, the statement added.

The Turkish army is supporting FSA fighters in liberating al-Bab, a strategic city for Daesh, from the terrorist group. Thursday marks the 177th day since the city was surrounded in order to liberate it.

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

Ankara has already vowed that Operation Euphrates Shield will continue in Manbij and Afrin, which are both held by the PKK's Syrian offshoot, the People's Protection Units (YPG), after al-Bab is liberated.
