Thailand's army has accused Cambodia of breaching a newly-signed ceasefire deal reached after weeks of deadly clashes that forced nearly one million people from their homes.

In a statement, the Thai army stated that more than 250 unmanned aerial vehicles (UAVs) were detected flying from the Cambodian side on Sunday night.

The ceasefire took effect at noon local time (05:00 GMT) on Saturday, with both countries agreeing to freeze front lines, ban reinforcements, and allow civilians in border areas to return home.

This ceasefire was seen as a diplomatic breakthrough, facilitated through negotiations backed by China and the US.

In a statement released on Monday, the Royal Thai Army expressed that Cambodia's actions constitute provocation and violate measures intended to ease tensions, arguing that they are inconsistent with ceasefire terms. The statement also suggested that Thailand may reconsider the release of 18 Cambodian soldiers held since July.

Thailand warned that it would be compelled to act if violations of agreements and national sovereignty persist. Meanwhile, Cambodia has yet to comment on these allegations.

This event follows a positive reception from Chinese officials regarding the ceasefire, and US President Donald Trump had previously praised the swift and fair agreement.

The ongoing tensions are part of a long-standing dispute between Thailand and Cambodia. The recent situation has escalated, particularly after a Cambodian soldier was killed during clashes in May, leading to one of the lowest points in the diplomatic relations between the two nations.

Past clashes have resulted in numerous casualties, with thousands displaced from their homes, highlighting the urgent need for a sustainable resolution.
