Turkish construction units found three explosive traps Sunday in a school which was used as a stronghold in the northern Syrian town of Jarablus by Daesh terrorists before the Free Syrian Army (FSA) captured the town in August.

Ankara's Keçiören Municipality workers, who have been working to restore a school and prepare it to receive students, found rope tied to one of the restroom doors, suspecting a booby trap.

The FSA fighters were immediately informed about the rope and called to the site, Keçiören Deputy Mayor Tekin Başer said. After drilling several walls of the restroom by following the rope, the FSA bomb squad found improvised explosives hidden in three bins and carried out a controlled detonation.

Başer said the restoration of the school is almost finalized and the building will be receiving students at the beginning of the week.

Turkish military launched an operation called Euphrates Shield last month to assist Free Syrian Army fighters take control of Jarablus from Daesh.

Turkey has said the operation aims to bolster border security, support coalition forces, and eliminate the threat posed by terror organizations, especially Daesh.

The operation is in line with the country's right to self-defense borne out of international treaties and a mandate given to Turkey's armed forces by its parliament in 2014, which was extended for another year in September 2015.
