THAILAND’S military accused Cambodia today of breaching a new ceasefire deal, just days after the signing of the agreement aimed at ending weeks of deadly clashes that have displaced nearly one million people.

In a statement, the Thai army said more than 250 drones had been detected flying in from the Cambodian border on Sunday night.

The ceasefire took effect at noon local time on Saturday, with both sides agreeing to freeze front lines, ban reinforcements and allow civilians in border areas to return home as soon as possible.

The deal had been seen as a breakthrough following days of talks, encouraged by China and the United States.

But the Thai army said Cambodia’s actions “constitute provocation and a violation of measures aimed at reducing tensions,” adding that they were “inconsistent” with the terms of the ceasefire.

It said Thailand “may need to reconsider” the release of 18 Cambodian soldiers detained since July, adding that Bangkok would be “obliged to act” if violations continued.

Cambodian Foreign Minister Prak Sokhonn described the incident as “a small issue related to flying drones seen by both sides along the borderline,” according to the Agence France-Presse news agency.

The accusation came hours after China’s Foreign Minister Wang Yi praised the “hard-won” ceasefire, while US President Donald Trump welcomed its “rapid and fair conclusion.”

China also announced 20 million yuan (£2.11m) in emergency humanitarian aid for Cambodia, with food, tents and blankets arriving on Sunday.

The dispute between Thailand and Cambodia dates back more than a century and centres on contested border areas.

Tensions escalated earlier this year after a confrontation near a disputed temple, culminating in five days of fighting that killed dozens of people and displaced thousands.

A truce signed in October broke down earlier this month, with both sides blaming each other for renewed clashes.
