A Thai soldier killed many on Saturday in a livestreamed mass shooting across several locations in a northeastern city, police said.
The rampage took place at a major shopping mall around 260 kilometers north-east of Bangkok, in Nakhon Ratchasima province, also known as Korat.
Royal Thai Police spokesman Krissana Pattanacharoen said more than 10 people had been killed.
"The gunman used a machine gun and shot innocent victims resulting in many injured and dead," a police spokesperson told Agence France-Presse (AFP), with local media reporting as many as 12 fatalities.
"I cannot confirm the death toll right now, police sealed off the area."
The gunman, identified by police as Sergeant Major Jakrapanth Thomma, stole an army vehicle and also posted photos and video of himself in full tactical gear as the attack was carried out. Video and photos circulating online showed panicked scenes, with people fleeing and what appeared to be the sound of automatic gunfire filling the air.
Police in the province said they have sealed off a Terminal 21 shopping mall but have yet to capture the gunman.
Thai news outlet Matichon published posts from social media users inside the mall who said they were hiding from continuous rounds of gunfire.
Thailand has one of the highest rates of gun ownership in the world but mass shootings by soldiers targeting civilians are rare. Several shootings at courthouses late last year also renewed concern about gun violence in the Southeast Asian country.
In one high-profile case, two lawyers were shot dead by a clerk at a court in the east of the country during a hearing over a land dispute.
