On December 23, 2025, police in Khok Sung district, Sa Kaeo province, reported that Cambodian BM-21 rockets struck civilian areas on the evening of December 22, damaging three homes and injuring six people, including one police officer. Two of the injured were reported to be in serious condition.
Pol Col Sutthipong Inthasit, chief of Khok Sung police station, said village leaders reported BM-21 impacts in multiple locations: Ban Khlong Takhian (Village 4), Nong Waeng subdistrict, as well as Ban Nong Samet (Village 10) and Ban Nong Sim in Khok Sung subdistrict. He reported the incident to provincial police commanders. The injured included five civilians and one police officer:
Officials said damage was also reported to several homes and cattle pens, with assessments still under way. At 4.45pm on December 22, Sa Kaeo governor Parinya Phothisat and Khok Sung district chief Naris Palakawong Na Ayutthaya visited Khok Sung Hospital to check on the injured and coordinate assistance with relevant agencies.
In a separate update at 6pm on December 22, the First Army Area Operations Centre summarised the border situation in Sa Kaeo, describing it as the 15th day of operations by the Burapha Task Force. It said clashes were taking place in three areas:
The centre said the Royal Thai Air Force deployed F-16s to strike two military targets opposite Ban Khlong Phaeng and Ban Nong Chan. It also said the Burapha Task Force struck a Cambodian military target in the Poipet area opposite Tha Kham subdistrict, Aranyaprathet district, which it identified as a building linked to a scam network allegedly used as a sniper position and for anti-drone systems.
The First Army Area also reported one Thai fatality from clashes in Ta Phraya district: Sgt Maj Kampanat Thongsaeng, of the 1st Infantry Battalion, 21st Infantry Regiment (King’s Guard).
Sa Kaeo authorities have ordered evacuations in four border districts. Officials said 40 temporary shelters were operating, housing 17,441 people.
Thai military units also claimed they had detected Cambodian BM-21 launchers being moved into villages and concealed near community areas and schools, and alleged that villages were being used to resupply rockets—an arrangement Thai officials said appeared designed to deter counterstrikes due to the risk to civilians.
