The assailant, a 19-year-old former student, ​used a shotgun in the attack in ⁠the Siverek district.

The wounded were taken ​to hospital, with five later transferred to facilities ​in Sanliurfa city centre for further treatment, Sildak said.

He later told broadcaster NTV that the attacker opened ​fire indiscriminately, starting in the school yard ​before entering the building.

The shooter killed himself as ‌police ⁠attempted to apprehend him, Sildak added.

Sildak said the attacker had no prior criminal record and that the school had previously been classified ​as safe ​by police.

The ⁠Interior Ministry said 10 of the wounded were students, four were ​teachers, one was a police officer ​and ⁠another a school canteen employee.

The condition of the wounded was not immediately known.

Video footage showed ⁠students ​fleeing the school as ​ambulances and police vehicles arrived at the scene.
