AP reports that police officials said at least four people were killed. Footage released by Reuters shows a large number of police officers, health workers, firefighters, and civilians outside the school where the shooting occurred. This is the second school attack in Turkey in two days, following a shooting at a high school in the Siverek district yesterday. The footage captured the moment an armed teenager entered the school hallway with a shotgun, while students and teachers tried to hide. According to the latest information, 16 people were injured in the attack.
