At least 16 people have been injured after an ex-student opened fire at a high school in south-eastern Turkey. The attacker, who was in his late teens, fired indiscriminately with a shotgun before killing himself with the weapon, local governor Hasan Şildak said. Those injured include 10 students, four teachers, a cafeteria worker, and a police officer. The incident happened around 09:30 local time (06:30 GMT) at the Ahmet Koyuncu Vocational and Technical Anatolian High School in Siverek district and has since led to an evacuation of the premises. The wounded were taken to hospital, with five later transferred for further treatment. An investigation into the incident has been launched. Şildak mentioned that the attacker had no criminal record and that the school was previously considered safe. Witnesses described the shooter as a young man who opened fire as soon as he entered the schoolyard, causing panic among students and faculty. One student recounted how he and his classmates had to jump out of windows to escape the chaos.
