AT least six people have been killed after a gunman opened fire near a busy food market in Thailand.

Thai police have launched an investigation after several shots rang out near the Or Tor Kor market in Bangkok.

Footage appeared to show the shooter holding a handgun and running through a car park from the market’s entrance gate.

He can be seen wearing a black T-shirt and carrying a backpack on his front.

The man is said to have arrived at the market after 1pm local time and began firing multiple rounds, Matichon reports.

He fled the market before shooting himself dead, authorities confirmed.

The victims of the mass shooting include security guards and market vendors, according to local media.

Worapat Sukthai, deputy police chief of Bangkok’s Bang Sue district, said: “Police are investigating the motive. So far, it’s a mass shooting.”

Authorities are in the process of identifying the shooter and are also exploring a “possible link” to the ongoing border tensions between Thailand and Cambodia.

Or Tor Kor Market is a major tourist destination in Bangkok, filled with visitors every weekend.

It comes as Thailand and Cambodia are trading attacks amid an ongoing border dispute.

Thailand has rained down strikes using its F-16s in response to Cambodia firing BM-21 rockets.

The long-running border dispute has seen artillery, tanks and troops battling it out on the ground.

The fighting flared last Thursday after a land mine explosion along the border wounded five Thai soldiers.

Both sides blamed each other for starting the clashes, which have killed at least 35 people and displaced more than 260,000 people on both sides.

In Thailand, clashes have centred around the Ubon Ratchathani and Surin provinces.

Cambodian Prime Minister Hun Manet and Thai Acting Prime Minister Phumtham Wechayachai are scheduled to hold talks on Monday.

This meeting was a result of direct pressure from President Donald Trump, who has warned that trade relations with both nations could be severed if hostilities persist.

Wechayachai previously said that if Cambodia refuses to stop their strikes soon, it would be risking an all-out war.

Speaking to journalists in Bangkok, he stated: “We’ve attempted to reach an agreement as we are neighbours, but we have now directed the Thai military to respond immediately if an urgent situation arises.”
