The Sûre river has been affected by an oil spill in Belgium, causing hydrocarbon pollution as far as the Luxembourgish border.

Belgian authorities have launched an investigation into the origins of the pollution, triggering the international Moselle-Saar alert plan.

Luxembourg's Water Management Administration (AGE) sent units to Rombach-Martelange to clear the pollution, accompanied by teams from the Grand Ducal Fire and Rescue Corps. As of Thursday afternoon, the operation has been largely unsuccessful due to the high water flow of the river, which hindered attempts to set up floating dams.

According to the AGE, the pollution quantities and significant distance between the spill and the Upper Sûre Lake dam should mean there is no imminent risk to drinking water.
