At least seven people have been killed in renewed border clashes between Thailand and Cambodia, officials confirmed on Tuesday. Cambodian authorities reported that two civilians were killed overnight in Banteay Meanchey province after Thai forces shelled the area, bringing the total death toll to seven. Earlier, four Cambodian civilians were killed and ten injured in artillery fire along the Preah Vihear and Oddar Meanchey border zones.

The Thai military said one of its soldiers was killed and 18 others wounded since the fighting began on Sunday. Both sides have accused each other of initiating the latest round of hostilities, which included airstrikes and the use of tanks by Thai forces. The violence marks one of the deadliest flare-ups in recent years along the disputed frontier.

The conflict stems from a century-old border disagreement dating back to the French colonial era, with both nations claiming sovereignty over several temple areas. Regional observers warn that continued escalation could undermine ASEAN stability and call for urgent diplomatic intervention.
