Border Tension Flares Briefly Near Si Sa Ket Patrol Route

Thailand’s army said Cambodian forces fired a single 40mm mortar round near a Thai patrol in Si Sa Ket province on the morning of 24 February 2026. Thai troops responded with an M79 grenade launcher round, which the army described as a warning shot and an act of self-defence under its rules of engagement. Officials said no Thai personnel were injured and no casualties or damage were reported after the short exchange. The military added that the situation stabilised quickly, with no further retaliation, while troops in the area were ordered to stay on heightened alert. Thai authorities also said the incident appeared inconsistent with a prior ceasefire understanding and suggested it may have involved newly rotated Cambodian personnel unfamiliar with procedures.
