Key Takeaways:
A 14-year-old student killed seven people in a rampage that began at his home and ended at his Bangkok-area high school, the latest in a string of shootings in a country with Southeast Asia's highest gun-ownership rate.
A 14-year-old Thai student killed seven people Friday, fatally shooting his grandparents at home before attacking his high school outside Bangkok with his grandfather's 9mm handgun, police said.
"From interviews with his close friends, police learned that he had been under stress over his studies and had complained about it," Prime Minister Anutin Charnvirakul said after being briefed by investigators. "I understand that his grandmother was a teacher and wanted him to perform well in school, and she was quite strict and demanding."
The shooter killed two teachers and three other staff at Debsirin Nonthaburi School in Nonthaburi province, then turned the gun on himself and died at a hospital. Nine people, including two students, were in critical condition, the health ministry said, while more than 20 others were injured. Police said he fired at least 26 bullets and was found with 34 additional rounds in his bag.
The attack renews scrutiny of gun ownership in Thailand, where civilians hold an estimated 10.3 million firearms — about 15 per 100 people, the highest rate in Southeast Asia and second in Asia only to Pakistan, according to a 2017 Small Arms Survey estimate.
The gun was legally registered to the boy's grandfather, with whom he lived, police said. The suspect shot the grandparents before traveling to the school, which enrolled about 3,100 students and 147 teachers in the 2025 academic year, according to district authorities.
Thailand's deadliest recent mass killing came in October 2022, when a dismissed police sergeant used a gun and knife to kill 37 people, including two dozen toddlers at a daycare center in the northeastern province of Nong Bua Lamphu. A soldier angry over a land dispute killed at least 29 people in a 16-hour rampage in Nakhon Ratchasima in February 2020.
The country has seen repeated school and public shootings since. In February, a 17-year-old stole a police gun and opened fire at a high school in southern Hat Yai, killing one person and wounding two. A gunman killed five people at a Bangkok fresh food market in July 2025 before taking his own life. In October 2023, a 14-year-old used a modified handgun to kill two people at a major Bangkok shopping mall.
The 2023 mall shooting prompted then-Interior Minister Anutin to order a short-term ban on new gun licenses, import restrictions, and a ban on people under 20 using shooting ranges. Longer-term measures required a medical certificate assessing the mental health of gun owners and set a validity period for some licenses.
Gun laws in Thailand are strict — possession of an illegal firearm carries a prison sentence of up to 10 years — yet ownership remains high relative to regional peers. The Small Arms Survey found about 4.1 million of the country's civilian firearms were unlicensed. A government program allowing police and soldiers to buy subsidized weapons has contributed to the number of unregistered guns in circulation, experts say.
The shooting is unlikely to move Thai financial markets directly, but it could sharpen the domestic policy debate over gun control ahead of any legislative response. The government has not yet announced new measures following Friday's attack.
