Military news, December 15, 2025, Avia.pro. The Cambodian Ministry of Defense accused Thailand of using chemical weapons along their shared border, announcing the incident in an official statement released today, December 15. Details of the incident remain scarce: the ministry did not specify what substance the Thai military may have used, but assured that an investigation is underway to confirm the facts. This accusation is the latest escalation in a long-running border conflict, which has escalated following recent fighting that has left at least 10 people dead.

The conflict, rooted in disputes over borders dating back to French colonial times, escalated in 2025 due to disputes over an 11th-century temple and ongoing minefield incidents. Cambodia previously accused Thailand of escalating tensions, including airstrikes and ground operations, and has now added accusations of the use of banned substances, which could lead to an international investigation.
