A student opened fire at a high school outside Bangkok on Friday, killing at least five people and wounding more than 20, according to authorities, who said he also appeared to have killed his two grandparents at the family home earlier in the morning.
The 14-year-old shooter took his own life at the school, officials said.
Five school staff members, including teachers and administrators, died in the shooting around 10 a.m. at Debsirin Nonthaburi School in Nonthaburi province northwest of Bangkok, Deputy Interior Minister Polapee Suwunchwee said at the scene.
The boy also killed his grandparents at the home he shared with them prior to the school shooting, Polapee said.
Bangyai Hospital, about five kilometers (three miles) from the school, said 23 people were wounded, of whom 10 were in critical condition, with most suffering gunshot wounds. Earlier reports gave conflicting casualty numbers.
A witness said students hid inside a classroom while they heard gunshots from another building before police officers knocked on the door and cleared a way for them to leave the building.
Amporn Niamfuang, who owns a restaurant 50 meters (160 feet) from the school, said there was the sound of a single gunshot and then a pause.
“And then there were multiple continuous shots,” Amporn said, recalling the narrow road outside the restaurant filling with fleeing students. “Students were running scared and pouring onto the street. Young girls were holding each other’s hands and crying. I went inside to hide.”
Prime Minister Anutin Charnvirakul, speaking after touring the school, confirmed reports that the shooter was 14 and had killed himself. He said the student had shown signs of stress connected to school.

The gun, described by police as small and compact, was legally registered to his grandfather, he said.

About an hour after the shooting, people stood outside comforting one another as police and first responders walked around the co-educational state school, which has an enrollment of about 3,000 students ranging from 12 to 18 years old.
All classes will be suspended between Aug. 10 and Aug. 14 and school staff have been instructed to work from home during that time, the school said.
Police find grandparents dead at family home
After the shooting, police went to his home and found both grandparents dead of apparent gunshot wounds, regional police Commander Wattana Yeejeen said.
The student appeared to have shot them before attending school as normal. He waited until classes started and began shooting inside his classroom before walking out and firing more shots, Police spokesperson Trairong Piwpan said.
The boy fired more than 20 shots and police found he still had 30 rounds after shooting himself, he said.
Several family members, including his uncle and sisters of the grandfather who were at the family home while police investigated, said he usually kept to himself and was a good student.
The family members said they were unaware of any troubles he faced at home or school.
Thailand has high rate of gun owners
Thailand has one of the highest rates of gun ownership in Asia, second only to Pakistan and far surpassing its Southeast Asian neighbors.
Data collected in 2017 by the groups Small Arms Survey and GunPolicy.org in their last extensive international study found civilian gun ownership in Thailand was about 15.1 guns per 100 people, compared with less than one per 100 in neighboring Malaysia.
Thailand had 3.49 deaths by firearms per 100,000 people, according to 2023 statistics published by World Population Review. That puts it well behind parts of Latin America and the Caribbean, but relatively high in Asia. Only the Philippines is higher in Southeast Asia.
In February, a 17-year-old stole a gun from police and opened fire at a public high school in southern Thailand, briefly taking people hostage in a two-hour attack that killed one person and injured two others.
A 14-year-old boy was accused of a 2023 shooting at a major Bangkok shopping mall.
