Renewed clashes along the contested frontier between Thailand and Cambodia have escalated sharply, resulting in at least twenty deaths and prompting the mass displacement of civilians on both sides of the border.

Heavy weapon exchanges, including airstrikes by Thai forces and artillery and rocket fire from Cambodian units, have marked some of the fiercest combat seen since a fragile ceasefire collapsed earlier this month.

The violence has uprooted more than half a million people, forcing families to flee their homes and seek refuge in evacuation centres amid fears of further escalation.

The latest outbreak of violence followed a skirmish that wounded Thai soldiers, undermining a U.S.-brokered ceasefire that had briefly paused hostilities in October under the Kuala Lumpur Peace Accord.

Both capitals traded blame for initiating renewed attacks, with Thailand asserting that Cambodian forces fired rocket launchers and mortars at its positions and Cambodia accusing Thai jets of bombing across the borderline.

Civilians, including children and the elderly, have been among the casualties, drawing international concern over the humanitarian toll.

Thailand’s military operations have involved fighter aircraft striking what it identified as Cambodian military targets near disputed areas including around the Preah Vihear World Heritage Site, while Cambodian authorities describe the use of heavy weapons by Thailand as violations of international law.

Both sides maintain that their actions are in defence of sovereign territory, reflecting the deep-rooted and unresolved territorial contest that has periodically flared into violence along the roughly 817-kilometre boundary.

The severe human consequences of the clashes have underscored the fragility of peace efforts in the region.

With tens of thousands of residents displaced and infrastructure damaged, international calls for restraint and renewed diplomatic engagement have intensified.

United States diplomatic efforts — including recent discussions by former President Donald Trump with the leaders of both countries — aim to revive ceasefire commitments, but remarks from Thai and Cambodian officials have suggested that any cessation of hostilities remains tenuous.
