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, he said. The incident happened at around 09:30 local time (06:30 GMT) at the Ahmet Koyuncu Vocational and Technical Anatolian High School in Siverek district, which has since been evacuated. The wounded were taken to hospital, with five later transferred to other facilities 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 considered safe by police. Witnesses recounted the horror of the moment, describing the gunman as a young man who entered the school and began shooting at anyone in sight. One injured student noted that the gunman did not speak and simply started firing at those present in the classrooms.
