At least one person was killed in Cambodia on Wednesday (Nov 12) as tensions flared with Thailand, with both countries accusing each other of opening fire along a disputed section of their border, putting a US-mediated truce at risk. Earlier, Thailand’s foreign ministry demanded an apology from Cambodia, alleging that new landmines laid by Cambodian forces had injured a Thai soldier on Monday. The day before, Thailand announced it was suspending an enhanced ceasefire agreement that the two nations had signed last month in the presence of former US President Donald Trump. Cambodia denied the allegations of laying new mines and urged Thailand to respect the October agreement, which built on an earlier truce brokered by Trump after five days of fighting in July.

According to Cambodia’s Defence Ministry, Thai troops opened fire near a contested border village at around 3:50 pm local time (4:50 pm Singapore time), resulting in one death and three injuries. Thailand’s Army spokesman, Major General Winthai Suvaree, said that Cambodian soldiers fired first and that Thai forces responded with warning shots following standard rules of engagement. The brief exchange lasted about ten minutes, and no Thai casualties were reported.

The village in question is claimed by Thailand as part of Ban Nong Ya Kaew in Sa Kaeo province, while Cambodia considers it part of Prey Chan in Banteay Meanchey province. The area has been the scene of previous clashes. Thai officials reiterated their demand for an apology over the recent landmine incident and called for measures to prevent future occurrences, though Cambodian authorities declined to comment on the request.

The July clashes between the two countries had killed at least 48 people and temporarily displaced around 300,000. Those confrontations involved heavy artillery, rocket fire, and airstrikes, with landmine explosions in disputed areas serving as one of the main triggers. Since July 16, at least seven Thai soldiers have been severely injured in mine-related incidents, some of which may have involved newly laid mines, according to expert analysis of materials shared by Thailand’s military. Thailand and Cambodia have contested sovereignty over undemarcated sections of their 817-kilometer border for more than a century, a boundary first mapped in 1907 under French colonial rule in Cambodia.
