Thai Official Denies Chemical Weapon Allegations Amid Border Tensions
The Director of the Thai-Cambodian Situation Information Center has formally rejected claims that the Thai military used chemical agents during border clashes.
On September 14, 2026, Air Chief Marshal Prapas Sonjaidee, Director of the Thai-Cambodian Situation Information Center, addressed allegations from Cambodia regarding the use of chemical weapons or substances during recent border conflicts. The claims, which have reportedly been brought to the attention of the Organisation for the Prohibition of Chemical Weapons (OPCW), were categorically denied by the Thai military.
Air Chief Marshal Prapas emphasized that the Thai Armed Forces operate under strict international law and established rules of engagement. He stated that there is no policy or directive authorizing the use of chemical weapons. Addressing specific claims regarding 61 types of substances and 395 alleged victims, the Director argued that these figures do not constitute scientific evidence. He challenged the Cambodian side to provide verifiable data, including details on the chain of custody for samples, the laboratories involved, and evidence linking any findings to Thai military actions.
For residents and travelers, this diplomatic and military friction highlights a period of heightened sensitivity along the border. While Thailand has expressed support for an impartial international investigation to resolve the matter, the situation remains fluid. Travelers in border regions should monitor local news for updates, as the verification of these claims is ongoing and the diplomatic environment remains complex.
