BANGKOK – The Thai Mine Action Centre (TMAC) has accused Cambodian forces of continuing to lay PMN-2 anti-personnel landmines along the shared border, alleging a blatant violation of the Ottawa Convention and recent peace agreements. The condemnation follows a landmine explosion that severely injured a Thai soldier on Saturday.
