A shooting at Debsirin Nonthaburi School in Thailand's Nonthaburi province left seven dead, including the suspected 9th-grade student shooter who died by apparent suicide, with 15 others injured.

A fatal shooting at Debsirin Nonthaburi School in Bang Kruai district claimed seven lives on Friday, according to local authorities and media reports. The deceased included three students, three teachers, and the suspected gunman. An additional 15 people sustained injuries in the incident and were transported to nearby hospitals for treatment.

Police identified the suspected shooter as a 9th-grade student who was armed with a 9mm handgun. Following the attack, the gunman barricaded himself on the third floor of the school's pink building before being found dead from what authorities described as self-inflicted injuries. Investigators have also alleged that the shooter had killed his grandparents prior to the school incident, though details remain under investigation.

Authorities rapidly mobilized emergency response teams to evacuate students and staff from the campus. Forensic police launched investigations to determine the motive behind the shooting and reconstruct the sequence of events. Officials requested the public to refrain from livestreaming the incident and avoid the area to prevent interference with ongoing operations.

The shooting marks another violent incident in Thailand within recent days. On July 22, five soldiers and six civilians were wounded when unidentified assailants opened fire and detonated explosives at a checkpoint in Narathiwat province, though details of that incident remain limited.
