Three Thai soldiers on patrol were wounded Saturday when one stepped on a land mine in territory along the border with Cambodia, Thailand’s army announced. The incident came just two days after the two countries reaffirmed their adherence to a ceasefire to end a brief armed conflict.

Thailand and Cambodia agreed to allow observers from Asean to inspect disputed border areas and prevent further hostilities.

Cambodia and Thailand's top defence officials began a meeting in Malaysia on Thursday to finalise a permanent end to hostilities following a violent five-day border conflict that ended in an unconditional ceasefire late in July.
