Two people have been killed in a shooting at a luxury shopping mall in the centre of the capital, Bangkok.
Four other people were injured in the incident at Siam Paragon centre, including a foreign national.
A suspect, 14, has been arrested after surrendering. He had been using a handgun, police said.
Prime Minister Srettha Thavisin said the situation had been brought under control at the centre, which is popular with both locals and tourists.
Earlier statements from Thai emergency services had put the number of dead at three and then revised it down to one before national police chief Torsak Sukvimol confirmed that two people had been killed.
One of the victims was Chinese and the other, who worked at the mall, was Burmese, he told a news conference.
Footage showed shoppers inside the Siam Paragon mall could be seen running for the exits after they heard multiple shots being fired.
By the time police arrived on the scene and were able to disarm the assailant, several people had been hit.
Ambulances had to battle with the notoriously busy rush hour traffic in this part of Bangkok to carry the victims to hospital.
The Siam Paragon mall is one of the most visited places in Asia and the most famous shopping mall in a city that has dozens of them.
In a statement, a Siam Paragon spokesperson said the mall expressed its deepest condolences to the victims and thanked police and the mall security team for their response.
“As soon as the incident occurred, the police and Siam Paragon’s security team immediately evacuated customers and employees from the building, prioritising the safety of all customers, employees, and tenants,” the statement said.
The teenaged suspect has been transferred to Pathumwan police station.
He attended a school close to the mall and had a record of getting treatment for a mental health condition at Rajvithi hospital, but had recently stopped taking his medication, Mr Sukvimol said.
It is unclear what his motives were.
Eyewitnesses inside the mall said they hid inside shops and bathrooms.
Jakkraphan Nakharisi, 29, an ice cream seller who has worked at the mall for two years, told the BBC that he did not realise at first that the noises were gunshots.
“There were four to five of them. And then silence. Then there were probably another two shots. Then I heard someone in my shop shout, ‘There’s some shooting!’
“I ducked behind the ice cream tank immediately. I didn’t know where to run. I thought I couldn’t just go out recklessly.”
He said he heard security guards escort people off the premises, before he left “no more than 10 minutes after the shooting”.
Mass shootings in Thailand are rare, although gun ownership rates are relatively high for the region.
An ex-policeman killed at least 37 people, most of them children, in a gun and knife attack at a childcare centre in in Nong Bua Lamphu province in north-east Thailand in October last year.
In 2020, a soldier killed 29 people and injured dozens more in the city of Nakhon Ratchasima.
