Zamboanga city Mayor Khymer Adan Olaso said the suspect apparently wore a body camera to live stream the attack at the high school on the Ateneo de Zamboanga University campus in his city. Two other people were injured, he said.

“A [seventh-grader] managed to enter carrying a high-powered firearm and a .45-calibre pistol,” Olaso told DZBB radio network.

“In the video, we see that he first shot at the teacher who was sitting at a table. It seems he missed, then moved to another room … he shot another student there, the one who fell,” Olaso said, referencing a video being circulated by local media.

The video, seemingly live-streamed on Facebook, shows the barrel of a gun moving down a hallway in the style of a first-person shooter video game before being pointed into a classroom and fired. Children in school uniforms are then seen screaming and rushing for an exit. The alleged shooter’s Facebook account has since been disabled.

Hundreds of students were evacuated to safety after the gunshots rang out in the high school building, which is in a secured campus, separate from a larger campus of the Catholic university, where its colleges and professional schools are located in the port city of Zamboanga.
