Renewed fighting between Thailand and Cambodia has entered its fourth day, with deaths climbing on both sides as the border conflict expands and diplomatic efforts struggle to keep pace.

According to Al Jazeera, the Thai military said eight Thai soldiers have been killed so far in the latest wave of clashes, with 80 more wounded. Thai officials also said three Thai civilians were killed, marking the country’s first civilian fatalities since the fighting resumed. Cambodia’s Ministry of the Interior said 11 civilians, including one infant, had died on the Cambodian side and that around 75 people had been injured.

The report said Cambodia accused the Thai military of carrying out attacks early Thursday using tanks and artillery against targets in several provinces, including Pursat, Banteay Meanchey and Oddar Meanchey. The two governments have each accused the other of violating international law and of starting the violence.

The fighting has already displaced large numbers of people. More than 500,000 Thai and Cambodian civilians have been forced to flee border areas, according to the AFP tally referenced in the broader reporting. That scale of displacement shows the conflict is no longer a limited military exchange but a humanitarian emergency.

The clashes also intersect with a broader diplomatic moment. Both sides were said to be waiting for a promised phone call from U.S. President Donald Trump, who had earlier helped push a ceasefire deal between the neighbors in Kuala Lumpur. The ceasefire, signed on October 26 and brokered with Malaysian Prime Minister Anwar Ibrahim, had been hailed at the time as a breakthrough. The renewed fighting now calls that breakthrough into question.

For civilians on both sides of the border, the latest toll is another reminder that ceasefires can be fragile when territorial disputes remain unresolved. The border between Thailand and Cambodia has long been a flashpoint, and the current fighting suggests the deeper political and military issues remain unsettled.

The reported deaths also highlight the asymmetry in impact. Soldiers are bearing much of the combat burden, but civilians are increasingly caught in the middle, especially in villages and towns near the frontier. Once artillery and tanks are used, the risks spread quickly beyond military positions.

As the fourth day ended, the conflict had become a test of regional diplomacy as much as battlefield strength. Whether external mediators can stop the escalation will determine not only the immediate casualty count but also whether the earlier ceasefire still means anything at all.
