Thailand and Cambodia have once again clashed along their shared border, breaking months of uneasy calm. On Sunday, troops from both sides exchanged gunfire in Thailand’s Si Sa Ket province, leaving at least two Thai soldiers injured. The Thai military reported that Cambodian forces opened fire around 2:15 p.m. local time, prompting a retaliatory response that lasted roughly 35 minutes. Thousands of residents from four Thai border provinces were evacuated to safety following the incident.

The skirmish occurred shortly after Thailand lodged a formal complaint at the United Nations, accusing Cambodia of secretly planting landmines inside Thai territory. Bangkok claimed that several Thai and Chinese nationals had been injured by the explosions and urged the UN to investigate. Phnom Penh has not yet issued an official response.

This latest confrontation threatens to unravel the fragile ceasefire brokered last July after a five-day conflict that killed 32 people. Regional observers warn that renewed hostilities could destabilize the broader Southeast Asian border region unless diplomatic channels reopen quickly.
