Thailand launched a series of air strikes with F-16 bombers along its disputed frontier with Cambodia on Monday, after both governments accused each other of breaching a US-brokered ceasefire. According to Cambodia’s Defence Ministry, Thai forces opened fire on Cambodian troops at 5:04am near the Preah Vihear and Ta Moan Thom temple zones, long among the most volatile border flashpoints. Cambodian officials said the sudden bombardment sent shockwaves across nearby villages, sparking immediate fears of a wider military escalation.
Schools along the Cambodia–Thailand border in Oddar Meanchey province were forced to shut down within minutes of the explosions. At Savy Chrum Primary School, teachers halted lessons as parents rushed in to pull children from classrooms and bring them to emergency shelters. Local administrators confirmed that some schools may remain closed indefinitely depending on the intensity of fighting. Oddar Meanchey’s deputy governor said authorities were “preparing safe places,” noting that families are moving out of high-risk zones as tensions worsen.
The latest assault followed clashes the previous afternoon when Thai troops reportedly opened fire with handguns and B40 machine guns on Cambodian soldiers in Preah Vihear’s Choam Ksan district around 2:15pm. Thai media reported that two Thai soldiers were injured in that exchange. Cambodian civilians living along the frontier have begun evacuating to monasteries, community halls, and makeshift camps, fearing retaliation and sustained combat. Witnesses described hearing “constant thuds of artillery” and seeing smoke rising from contested hilltop areas.
This renewed violence forms part of a long-running conflict rooted in the ambiguous border demarcation around the 11th-century Preah Vihear temple. Although the International Court of Justice ruled in 1962 that the temple itself belonged to Cambodia, the surrounding land remained disputed, leaving room for overlapping claims and repeated clashes. Tensions surged again in 2008 after Cambodia succeeded in registering Preah Vihear as a UNESCO World Heritage Site, a move that sparked protests in Thailand and prompted years of sporadic firefights from 2008 to 2011, killing soldiers on both sides and displacing thousands.
In 2013 the ICJ clarified that Cambodia had sovereignty over the temple and its immediate vicinity, but the broader border questions remained unresolved. The area has since become a symbolic battleground of nationalist narratives: Thai factions often accuse Cambodia of encroachment, while Cambodian officials argue that Thailand refuses to accept international rulings. Military analysts note that both governments face domestic political pressures, making border flare-ups especially combustible.
The now-collapsed US-brokered ceasefire, signed earlier this year, was intended to prevent precisely this kind of escalation. However, repeated accusations of land-mine incidents, unauthorized patrols, and small-arms fire eroded confidence in the agreement. Human-rights monitors have repeatedly urged both sides to protect civilians, with one observer earlier warning that “schools, homes, and cultural sites sit directly in the line of fire unless both militaries exercise restraint.”
Monday’s air strikes mark one of the most serious escalations in years, raising questions about regional stability and the risk of a broader conflict. With residents fleeing border villages and students sheltering in emergency sites, authorities on both sides now face mounting pressure to restore calm before the confrontation spirals further.
