Thailand is mourning after a devastating shooting at a secondary school outside Bangkok left students, teachers, families and the wider community confronting a profound tragedy. The death of a 12-year-old girl who was critically injured in the attack has raised the confirmed death toll to nine, according to police.
The shooting occurred on Friday, August 7, 2026, at Debsirin Nonthaburi School in Nonthaburi Province. What began earlier that day as a deadly incident at a residence escalated into an attack at the school, leaving multiple people dead and others seriously injured.
According to authorities, a 14-year-old student allegedly fatally shot his grandparents at a residence before traveling to the school. Police said the teenager then opened fire on the school grounds, killing five teachers and staff members.
The suspected shooter later died from a self-inflicted gunshot wound, authorities said.
Among those caught in the school shooting was the 12-year-old girl who suffered critical injuries. She was transported for medical treatment but later died from her wounds. Police confirmed her death on Saturday, bringing the reported toll to nine.
Authorities have not publicly identified the girl in the information currently available. Her death has nevertheless become one of the most heartbreaking elements of the tragedy as families and residents mourn the loss of a child whose life was cut short.
Fourteen other people remained hospitalized following the attack, with seven reportedly in critical condition. Several of those injured were young students, with reports indicating that some victims were between approximately 12 and 14 years old.
Investigators said the teenager allegedly used a firearm belonging to his grandfather. Police reported that at least 26 rounds were fired, while additional ammunition was recovered afterward.
Inside the school, students and staff were confronted with a terrifying situation as gunfire erupted. Accounts from students and witnesses described children hiding inside classrooms, attempting to remain quiet and using desks to block doors while the attack unfolded.
Authorities eventually secured the school and began the difficult process of treating the wounded, accounting for students and staff and investigating the circumstances of the violence.
The investigation extends beyond the school because police say the teenager had allegedly killed his grandparents before traveling to the campus. Investigators are now working to establish a complete timeline and understand what preceded the killings and the subsequent attack.
Authorities are also examining how the teenager obtained access to the firearm and whether there were warning signs or other factors that may have contributed to the violence.
The deaths have sent shockwaves through Nonthaburi and across Thailand. Families are grieving loved ones, students are confronting the trauma of what they witnessed, and the school community is facing the devastating consequences of an attack that claimed the lives of teachers, staff and a young student.
As investigators continue their work, the community remains focused on the victims and those still receiving treatment. The death of the 12-year-old girl has deepened the grief surrounding an already devastating day and left many mourning a young life that ended far too soon.
