BANGKOK – In its situation report issued at 5pm on December 11, 2025, the Second Army’s Operations Centre said the current round of clashes began on December 7, when Cambodian troops fired on a Thai patrol at Phu Pha Lek in Kantharalak district, Si Sa Ket, wounding two Thai soldiers.
Cambodian forces then opened up with artillery and BM-21 multiple rocket launchers along the border in Ubon Ratchathani, Si Sa Ket, Surin and Buri Ram, damaging homes, farmland and health facilities. Thai forces responded under rules of engagement with proportionate direct- and indirect-fire, the statement said, to “intercept, deter and destroy threats” to civilians.
