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. It 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 said the attacker had no criminal record and that the school was considered safe by police.

One witness told IHA News: He was a kid, about 17-18 years old. Suddenly, he walked through the front door of the school yard. As soon as he entered, he pulled out a gun. It was a long, stocky one, like one of those pump-action shotguns with rims.

Another student, Ömer Furkan Sayar, recounted: First, we threw ourselves to the ground, then two of us jumped out of the window. He didn't say anything to us, he just came in and started shooting.
