BANGKOK (AP) — 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.

The incident occured only days after an agreement to extend a ceasefire that ended the recent deadly conflict between the Southeast Asian neighbors.

Cambodia and Thailand agreed to uphold a ceasefire, more than one week after a US-backed truce ended the deadliest clashes between the Southeast Asian neighbors in recent history.
