- Casualties: At least seven Cambodian civilians and one Thai soldier have been killed since hostilities resumed.
- Displacement: Tens of thousands of residents on both sides of the border have been forced to evacuate.
- Diplomatic Context: The violence breaks a ceasefire agreement signed on October 26, 2025, which was brokered by U.S. President Donald Trump.
Violent clashes along the Thai-Cambodian border intensified on Tuesday despite urgent appeals from the international community for calm, marking a significant collapse in diplomatic efforts to stabilize the region. Less than two months after a high-profile ceasefire agreement was signed under the auspices of the United States, heavy artillery and airstrikes have returned to the contested frontier, resulting in rising civilian casualties.
Both Southeast Asian nations have traded accusations regarding the instigation of this latest round of combat, which began late Sunday night. The rapid escalation has already displaced tens of thousands of villagers and claimed the lives of at least seven civilians in Cambodia and one soldier in Thailand.
“Patience” Runs Out
While Cambodian officials initially maintained a defensive posture, the rhetoric shifted sharply on Tuesday. Former Prime Minister Hun Sen, who remains a central figure in Cambodian politics, announced that the military had engaged in a full counter-offensive following Thai airstrikes on border zones earlier in the week.
According to a statement posted to social media on Tuesday morning, Hun Sen declared that Cambodian forces had exercised patience for more than 24 hours to respect the ceasefire and allow time to get the population to safety
before retaliating.
The influential leader’s message to the troops was uncompromising:
Our forces must fight everywhere the enemy has attacked. [You must] destroy enemy forces.

The Cambodian Ministry of Defense reported that Thai bombardment overnight targeting the border province of Banteay Meanchey resulted in the deaths of three additional civilians. This brings the civilian death toll on the Cambodian side to seven since the fighting reignited. Approximately ten others have been injured, including a local journalist.
Evacuations and Military Toll
On the opposing side, the Thai military confirmed its own losses, reporting the death of one soldier and injuries to 29 others on Tuesday. As artillery fire continued, authorities in both nations scrambled to evacuate tens of thousands of residents living within strikeforce range of the border.
Despite the danger, some locals expressed reluctance to abandon their homes and livelihoods. In Thailand’s Surin province, roughly 20 kilometers from the combat zone, residents faced difficult choices. Sutida Pusa, a 30-year-old grocery store manager, told reporters she hesitated to flee immediately.
I wanted to see the situation for myself first, because the fighting isn’t as loud as it was in July,
Pusa said. We don’t always trust what we are told.
A Fragile Peace Shattered
The renewal of hostilities has drawn immediate concern from the international community. UN Secretary-General António Guterres and the European Union issued statements on Monday urging both Bangkok and Phnom Penh to exercise maximum restraint
and pursue immediate de-escalation.
The conflict is rooted in a colonial-era dispute over the demarcation of the 800-kilometer border, a legacy of French Indochina that has left several areas contested. These tensions previously erupted in July, leading to five days of heavy fighting that killed 43 people and displaced 300,000.
Hopes for a lasting resolution were high following the October 26 accord, co-signed by U.S. President Donald Trump. However, the agreement began to fray just weeks after its implementation. Thailand suspended its participation following a landmine explosion that wounded several of its soldiers, accusing Cambodia of violating the terms.
While the October agreement included provisions for the withdrawal of heavy weaponry, demining operations, and continued dialogue, fundamental disagreements regarding the territorial claims were never resolved, leaving the region vulnerable to the rapid deterioration of security witnessed this week.
