The Second Army Area said on its Facebook page that Cambodian forces opened fire first, prompting Thai troops to return fire. The exchange escalated when Cambodian forces deployed recoilless rifles.
The clash ended at around 2.50pm, though Thai units remain on heightened alert.
Authorities warned that the situation remains unstable and could escalate. Residents in border districts of four provinces—Buri Ram, Surin, Si Sa Ket and Ubon Ratchathani—were advised to evacuate to designated shelters under the civilian evacuation plan.

Kantharalak chief urges village leaders to monitor situation
Kantharalak district chief, Somkuan Singkham, told Nation TV that the incident occurred at around 2.12pm and lasted roughly 10 minutes before the area fell quiet. He confirmed that one soldier had been shot in the leg, while another was hit in the chest but protected by his bulletproof vest. Both were sent to Kantharalak Hospital.
He said the gunfire originated from the Cambodian side, though the exact position was unclear. Prior to the clash, the Thai soldiers involved had been escorting road-construction teams near Phlan Hin Paet Kon in Si Sa Ket province.
Somkuan said he had instructed village heads and sub-district leaders to closely monitor the situation. No civilian evacuation order has been issued at this stage.
