An ex-policeman has killed at least 38 people, most of them children, in a gun and knife attack at a pre-school daycare centre in north-east Thailand.
Police say he then killed himself and his family after a manhunt following the attack in Nong Bua Lamphu province.
Children and adults are among the casualties at the nursery – police say the attacker shot and stabbed his victims before fleeing the scene.
The former officer, aged 34, was sacked in June for drug use, police said.
A teacher who survived the attack told Thailand’s Thairath TV the gunman used to drop off his child at the nursery and had seemed polite. A motive for the attack remains unclear.
At least 22 children were among the dead in the mass killing in the town of Utthai Sawan. Some victims aged as young as two were attacked as they slept. A dozen people who were injured have been taken to Nong Bua Lamphu district hospital.
“At first people thought it was fireworks,” she said, adding the gunman then forced entry to a locked room where children were sleeping.
Thai Prime Minister Prayuth Chan-ocha described the shooting as “a shocking event”.
Police named the attacker as Panya Kamrab, a local man who had been a police lieutenant colonel before he was dismissed last year for drug use. He is understood to have appeared in court on Thursday on charges related to the use and possible sale of methamphetamine.
Armed with a shotgun, a pistol and a knife, he stormed the nursery at about 12:30 pm (0530 GMT).
The details of what followed are still emerging, but after the killing spree the attacker fled the scene in a white-four door Toyota pick-up truck with Bangkok registration plates, according to police, who launched a search for him and warned locals to keep indoors for their own safety.
Police say Kamrab returned home, killing his wife and son before taking his own life.
Mass shootings in Thailand are rare although gun ownership rates are relatively high for the region. Illegal weapons are also common in the south-east Asian country, according to the Reuters news agency.
The nursery attack comes less than a month after an army officer shot dead two of his colleagues at a base in Bangkok.
In 2020 a soldier killed 29 people and injured dozens more in the city of Nakhon Ratchasima.
