Civilian Impact and Legal Assessment
As of 18 December 2025:
- 18 Cambodian civilians killed, including 1 infant
- 79 civilians injured
The Ministry of National Defence reiterates that Cambodia’s right to self-defence is exercised solely against Thai military targets and has never targeted civilians. In contrast, Thailand has deliberately attacked civilian communities, cultural heritage sites, and sacred temples.
Thailand’s use of F-16 fighter jets, naval warships, heavy artillery, cluster munitions, toxic gas, and advanced drone systems constitutes war crimes and grave violations of international law.
Cambodia’s Official Position
The Royal Government of Cambodia:
- Strongly condemns Thailand’s continued ceasefire violations
- Demands the immediate cessation of all hostilities
- Calls for full implementation of the Joint Declaration
- Urges Thailand to withdraw all forces from Cambodian territory
- Calls on the international community to condemn Thailand’s unlawful acts and war crimes
The Cambodian Armed Forces and National Police will continue to stand strong, brave, and steadfast, exercising Cambodia’s inherent right to self-defence to protect the nation’s territorial integrity, people, and sovereignty.
Conclusion
The events of 18 December 2025 confirm Thailand’s continued and escalating armed aggression against Cambodia for the 12th consecutive day. Through coordinated air, land, naval, and drone operations, Thai forces have gravely endangered civilian lives, cultural heritage, and regional stability. Cambodia remains resolute in defending its sovereignty while calling upon the international community to uphold justice, peace, and the rule of law.
