Summary

A student in the southern Philippines livestreamed himself shooting and killing another pupil at Ateneo de Zamboanga University before taking his own life, marking the country's second school attack in less than two months. The shooter was reportedly armed with a high-powered firearm and a .45-calibre pistol, which he managed to bring onto campus despite an ongoing investigation into how he obtained them. Philippine authorities are now trying to determine the motive behind the shooting and have ordered the preventive suspension of a customs agent who allegedly owned the guns used in the attack. The incident is the second school shooting in the Philippines this year, following a June attack at a public high school that killed three students and injured about 20 others.

Story summary

A ninth-grade student in Zamboanga, Philippines, Mohammad Mael Jalani, opened fire at a high school campus on Tuesday, killing a fellow student and himself while wounding two others. The attack was livestreamed using a body-worn camera, showing the suspect firing a gun down a hallway before entering a classroom and shooting another student. Authorities confirmed that the shooter had brought two pistols into the school, one of which belonged to his father, a customs police official. This is the second fatal school shooting in the Philippines in just two months, following an attack in June that killed three high school students. The incident has raised concerns about gun violence and access to firearms in Southeast Asia, where 10.3 million firearms are estimated to be possessed by civilians in Thailand alone.
