Cambodia warns floodwater can move mines and explosive remnants

Floodwater can move hazards beyond surveyed locations

The warning was reported on October 1, 2026 as authorities responded to flood risks. CMAA said flowing water can move explosive ordnance from contaminated ground and can also bury it more deeply, making its new position harder to predict.

The authority referred to landmines, anti-vehicle mines, cluster munitions and other remnants of war. Local authorities were told to step up risk awareness and place warning signs where explosive ordnance may be present.

That changes the safety picture after flooding. A location that was previously mapped or familiar to nearby residents may need to be treated differently if water has crossed contaminated land and disturbed the ground.

The warning is for contaminated and flood-affected areas

CMAA’s message is particularly relevant to people living or farming near contaminated land. Residents should avoid known hazardous areas, leave suspected ordnance untouched and report discoveries to local authorities so trained personnel can respond.

For farmers, the concern can continue after the water recedes, when fields, tracks and roadside ground are used again. Flood debris or fresh sediment may conceal hazards, while an object may no longer be where earlier information suggested it was.

Travellers do not need to treat every flooded part of Cambodia as a mine hazard. the concern is more specific: rural, former conflict and border areas where mines or explosive remnants are already known or suspected, especially after floodwater has passed through them.
