The shooting occurred at the Inci Uzmez Vocational and Technical Anatolian High School in the district of Turgutlu. All of the injured are reported to be students. CCTV footage broadcast by Turkish media appears to show the suspect, casually dressed, walking through empty streets carrying a shotgun before later fleeing the scene with the weapon still in hand.
The teenage suspect is reportedly a student at the school. Under Turkish law, he must appear before a court before being formally arrested. The motive for the attack is not yet clear.
Justice Minister Gürlek said the suspect's mother, father and grandfather — who reportedly owned the weapon — have also been detained. Turkey's Education Ministry said the incident had "deeply saddened our nation, and our educational community in particular", and announced that three national investigators had been sent to Manisa.
This is the third school shooting in Turkey this year. Two deadly shootings in April sparked outrage and led to the introduction of tightened security measures for the current academic year, though the recent spate of violence suggests those measures may not have been sufficient to prevent further attacks.
