Government Spokesperson Jirayu Houngsub stated that the Second Army Area on 2 September 2025 discovered a makeshift booby trap made from a mortar shell near Prasat Ta Khwai in Surin Province, which was later confirmed to be planted by Cambodian soldiers. This clear evidence indicated an intrusion by Cambodian forces onto Thai soil to plant explosives.

Mr. Jirayu, who is also member of Ad Hoc Center for Thailand-Cambodia Border Situation, said that the movements of Cambodian soldiers had been detected, and a Cambodian surveillance drone was also observed in the areas of Chong An Ma, Sattaphasom – Phu Phi – Don Tuan, and Chong Sai Taku. The anti-drone system was immediately deployed when the drone entered the Thai sovereign airspace.

The Government, through the Ministry of Defense, has ordered military forces and relevant security agencies to collect evidence to be sent to Ministry of Foreign Affairs to proceed with a formal protest to the Cambodian government. The military forces were also instructed to beef up their patrols and surveillance to prevent such further acts, protect national security, and ensure safety of the border people.

The 31st meeting of the Ad Hoc Center for Thailand-Cambodia Border Situation, chaired by Deputy Minister of Defense Gen Nattaphon Narkphanit, was held on 3 September to assess the situation and discuss the building of border walls along the Thai-Cambodian border in Sa Kaeo Province to tackle cybercrimes and human trafficking. The meeting also followed up on the progress of resolving problems concerning migrant workers.

Mr. Jirayu said that the Government continued to closely monitor the Thailand-Cambodia border situation, placing an emphasis on the safety of the people living along the seven provinces sharing borders with Cambodia.

It will also continue to protest Cambodia through diplomatic channels, and stands ready to take military action, if Thailand's sovereignty is blatantly violated.
