The attack took place on Tuesday morning at the junior high school campus of the privately run Ateneo de Zamboanga University in Zamboanga City, where police said a student brought weapons onto campus, opened fire inside a classroom and killed a fellow student. Investigators are still examining the sequence of events and the student’s motive.

Zamboanga Mayor Khymer Adan Olaso said in a radio interview on DZBB that the student had live-streamed the attack through a body-worn camera. Olaso also said that the gunman shot at a teacher and a Grade 10 student before taking his own life.

The shooter’s father, a customs police officer, was relieved of his duties after the attack as investigators looked into reports that the firearms used belonged to him.
