hailand has been left reeling after a 14-year-old student carried out a deadly shooting that claimed the lives of his grandparents and five staff members at a school near Bangkok on Friday, August 7, 2026.

According to police, the teenager first attacked his grandparents at their home before traveling to Debsirin Nonthaburi School in Nonthaburi province, where he opened fire inside the campus. Authorities said seven people were killed by the teenager, while more than 20 others were injured in the attack.

The terrifying incident triggered panic as students and teachers attempted to escape while emergency services and armed police rushed to the school.

Officials said five school staff members were among those killed. At least 23 people were reported injured, with several victims remaining in critical condition as they received treatment at nearby hospitals.

Police said the teenager used a firearm belonging to his grandfather. Investigators recovered ammunition as authorities began examining how the weapon was accessed and what may have led to the devastating attack.

The teenage gunman also died during the incident, police confirmed. Authorities are continuing to investigate his background and the circumstances leading up to the shooting.

Thai Prime Minister Anutin Charnvirakul expressed sorrow over the tragedy and indicated that the government would again look at strengthening measures aimed at controlling access to firearms.
