A 14‑year‑old boy shot his grandparents at his family home outside Bangkok, then travelled to a nearby high school where he opened fire on staff and students, killing eight people in total and wounding over 20 before turning the gun on himself, authorities said.
Chronology of the attack
According to Reuters and the BBC, the teenager first entered his grandparents' house in the early afternoon, firing multiple rounds that killed both grandparents. He then left the scene, drove to the school, and entered the campus armed with a pistol that police later identified as an illegally owned firearm.
At the school, witnesses said he targeted teachers in a classroom, killing five educators, while additional victims – including students – were hit as he moved through the corridors. The Bangkok Post reported that at least seven victims died at the scene, with the gunman's own death bringing the official toll to eight, a figure confirmed by the Thai prime minister’s office.
More than 20 people were treated for gunshot wounds, many of them taken to hospitals in the capital region, where they remain in serious but stable condition, the AP noted.

Government response
Prime Minister Anutin Charnvirakul announced an immediate review of Thailand’s gun‑ownership regulations, pledging “tougher gun laws” and a crackdown on illegal weapons.
"We will introduce stricter gun laws and ensure that firearms do not fall into the hands of children," the prime minister said, according to the BBC.
The prime minister’s office added that the cabinet will consider new licensing requirements, tighter background checks, and harsher penalties for unregistered weapons. The statement echoed earlier promises from the government to maintain a “tough policy on gun ownership,” as reported by the Thai Examiner.
Broader implications
Thailand has traditionally seen few mass shootings, making this incident the deadliest school attack in the country in years, as noted by The New York Times and CNN. The event has reignited a public debate about gun control, with analysts from GZERO Media and AnewZ highlighting the need for comprehensive reforms to curb the circulation of illegal firearms.

Human‑rights groups and education officials have called for increased security measures in schools, including metal detectors and stricter visitor screening. Meanwhile, the police continue to investigate how the teenager obtained the weapon, with early reports suggesting it was not registered to any family member.
The tragedy also prompted a surge of solidarity among Thai citizens, with candlelight vigils held outside the school and across the country. Teachers’ unions have demanded counseling for survivors and the implementation of safety protocols to prevent future incidents.
As the investigation proceeds, authorities have urged the public to provide any information that could clarify the chain of custody of the gun and the motives of the young shooter. The case remains under active police scrutiny, and a full report is expected in the coming weeks.
