The Cambodian Ministry of National Defence says Thai forces carried out a series of attacks inside Cambodian territory on December 15, including air strikes by fighter jets that penetrated deep into the country.
In a statement, the ministry said Thai military units launched 15 attacks over ten hours, beginning at 4.30 in the morning and continuing until 2.42 in the afternoon. It claimed that Thai F-16 aircraft dropped bombs as far as 70 kilometres inside Cambodia, near an area sheltering displaced civilians.
According to the ministry, the attacks targeted multiple locations along the border and beyond, including O’Smach, Prasat Khnar, Chub Angkunh, Prasat Ta Moan Thom, Thmor Don, Prasat Ta Krabey, and the Preah Vihear temple area in Preah Vihear province. Shelling was also reported in Samraong town in Oddar Meanchey province, which officials described as a civilian-populated area.
Additional strikes were reported in Prey Chan village, Chouk Chey village, the Boeng Trakuon border crossing, and Preah Netr Preah district in Banteay Meanchey province, as well as Thmor Da commune in Veal Veng district of Pursat province.
The defence ministry said other areas remained calm but stressed that Cambodian forces were on high alert and continuing close monitoring. It said troops were prepared to defend Cambodia’s territorial integrity on all fronts.
On the same day, Thai ground forces reportedly seized several GAM 102LR anti-tank missiles abandoned in the An Ses battlefield area, also known as Hill 500. The missiles have a range of about 10 kilometres and are designed to track armoured vehicles. They are produced by the Chinese company Poly Technologies and were recently displayed at an arms exhibition in Cairo earlier this month, with a reported unit price of 112,000 US dollars. Thai investigators are said to be examining how the weapons came into the hands of Cambodian forces so quickly.
The claims come as fighting between Cambodia and Thailand enters its ninth day, with the international community urging both sides to return to negotiations to end the conflict.
On December 15, Chinese foreign ministry spokesperson Guo Jiakun wrote on social media that China hoped both countries would exercise maximum restraint and take all possible steps to stop the fighting and reduce tensions as soon as possible. He said China would continue to do everything it could to support a ceasefire and the restoration of peace.
Separately, the Wall Street Journal reported on December 13, 2025, that United States President Donald Trump had warned of new tariffs on both Thailand and Cambodia if the conflict did not end. He was quoted as saying that Washington could suspend trade agreements and impose additional customs duties if fighting continued.
However, Thai PBS quoted Thai army chief Chaiyapruek Duangpraphat on December 14 as saying Thailand’s long-term objective was to ensure that Cambodia no longer posed a threat to Thai national security. He said this would require neutralising Cambodia’s military capabilities by targeting its military equipment and infrastructure.
