8/20/2026, 12:18:55 AM
Core Event
On August 18, 2026, a ninth-grade student entered the junior-high building of Ateneo de Zamboanga University (AdZU), brandished a pistol and a rifle, and opened fire inside two classrooms. He first fired at a teacher, missed, then shot a male Grade 10 student on the fourth floor. He ascended to the fifth floor and took his own life. Police confirmed two fatalities—the shooter and the Grade 10 victim—and reported two additional injuries. The incident was livestreamed via a body-worn camera and briefly appeared on Facebook Live.
Background & Context
School shootings are rare in the Philippines, where gun ownership is tightly regulated but an illegal firearms market persists. A similar tragedy occurred on June 22, 2026 in Tacloban City, prompting the Department of Education to order active-shooter drills and security upgrades. AdZU conducted its first full Human-Induced Simulation Exercise (SIMEX) on July 18, 2026, a month before the August attack.
Data & Statistics
- Fatalities: 2 (shooter, Grade 10 student)
- Injured: at least 2 (reports vary)
- Weapons: one pistol and one rifle; a .40-calibre pistol was issued to the shooter’s father, a Bureau of Customs officer, and a second firearm was registered to the father’s licence
