In a tragic event on Tuesday, an ex-student unleashed gunfire at a high school in southeastern Turkey, injuring at least 16 individuals before taking his own life, according to an official report.

The 18-year-old, wielding a shotgun, targeted a vocational high school in the Siverek district of Sanliurfa province. He randomly fired shots before retreating into the building to hide.

Governor Hasan Sildak confirmed that the young man ultimately ended his life using the same firearm.

Among those hurt, a teacher was reported to be in critical condition, as per NTV television’s updates.

Authorities have not yet determined the attacker’s motive. Incidents like this are uncommon in Turkey.

Special police units were called to the scene when the suspect refused to give himself up, while all students and faculty were safely evacuated, according to NTV.

Video footage showed dozens of students running out of the school toward the gate and onto the street.
