Three Thai soldiers were injured by a landmine while patrolling the border with Cambodia, the Royal Thai Armed Forces said, days after the two countries agreed to a detailed ceasefire following last month’s violent five-day conflict.

“One soldier suffered a severe leg injury, another was wounded in the back and arm, and the third had extreme pressure damage to the ear,” Al Jazeera quoted the Royal Thai Armed Forces as saying.

Cambodia said it “has yet to receive clear confirmation from Cambodian frontline forces concerning the explosion,” adding that its army “has been strictly respecting the spirit of the ceasefire”. Thailand stated the incident occurred within its territory in an area recently cleared of landmines.
