At least six people were killed and 15 injured after a shooter opened fire at a high school in Thailand on Friday, local news media said, citing Thai authorities.

The authorities said the shooting occurred in the morning at Debsirin Nonthaburi School, northwest of Bangkok, the capital, and ended when the shooter, a student of the school, turned the gun on himself. Among the dead were three teachers and three students, the reports said. The condition of the shooter was not immediately clear.

Thailand, which has one of the highest rates of civilian gun ownership in Southeast Asia, has in recent years seen several deadly high-profile mass shootings, which have fueled calls for stricter firearm controls in the country.

In 2022, a 34-year-old former police officer fatally shot or stabbed 36 people — most of them children — at a day-care center in Nong Bua Lamphu province.

One year later, a 14-year-old shooter opened fire at one of Bangkok’s largest shopping malls, killing two and wounding five others.

Last year, a 61-year-old man opened fire at a marketplace in Bangkok, killing five and wounding two others.

This is a developing story.
