Thailand has declared martial law in several districts of its eastern Trat province following escalating border clashes with Cambodian forces. According to Thai media reports on Sunday, the move came after a Thai army staff sergeant was killed by a BM-21 rocket strike while on duty near the frontier. The Defense Ministry confirmed that the navy has also imposed curfews across four districts as fighting continues to intensify. Under martial law, Thai security forces have been granted expanded powers to detain suspects, search vehicles, and inspect properties without prior authorization. Rear Admiral Parach Rattanachaipan of the Thai Navy stated that marine units had regained control over key areas in Cham Rak subdistrict after heavy combat. Senior military officials emphasized that Thailand’s strategic goal is to prevent Cambodia from posing a long-term security threat. Cambodia’s Defense Ministry, however, accused Thailand of shelling multiple villages and conducting airstrikes using F-16 fighter jets. Regional observers warn that the escalation could destabilize cross-border trade and humanitarian conditions if diplomacy fails to de-escalate tensions.
