According to Army spokesman Maj Gen Winthai Suvaree, the incident took place on May 21, 2026, while personnel from Ranger Company 2603 under the Suranaree Task Force were improving defensive positions and strengthening security near Border Marker 18 in Kap Choeng district, Surin province.

At around 2.20pm, Thai personnel heard five rounds of small-arms fire coming from the south, approximately 600 metres away, in an area under Cambodian control. After stopping to assess the situation and observe the area, troops reported no irregularities and resumed their mission.

The Army confirmed that no Thai personnel were injured during the incident. Thai forces also did not return fire, with Maj Gen Winthai stating that troops avoided responding in order to prevent revealing their positions and deployment.

The Suranaree Task Force said units stationed along the border remain on alert and are continuing to follow established rules of engagement based on the situation on the ground. The Army added that, although the firing appeared to be long-range harassment, it was considered a clear violation of the existing joint statement between the two sides.

The border area in Surin province has seen periodic tensions in the past, with both Thai and Cambodian forces maintaining a military presence in sensitive areas near the frontier. The latest exchange comes as authorities on both sides continue coordination efforts aimed at preventing escalation along the border.

In response to the gunfire, the Suranaree Task Force said it would issue a formal warning and lodge a protest with the Cambodian side through local coordination channels. Thai military officials stressed that forces in the area remain prepared to respond if necessary while continuing to avoid actions that could worsen tensions.

Security analysts have previously noted that even isolated incidents along disputed or sensitive border areas can increase strain between neighbouring forces if not quickly addressed through military coordination mechanisms.

The Nation reported that Thai authorities have not announced any additional security measures following the incident, but troops operating in the area have been instructed to maintain heightened vigilance while carrying out ongoing defensive operations near the border.
