For reasons as yet unknown, a lorry overturned on the carriageway and lost a large part of its cargo, which spilled onto the motorway.
Emergency services and police quickly arrived at the scene of the incident, securing the area and closing off the affected slip road.
Extensive cleanup operations are underway and are expected to continue throughout the afternoon. To ensure traffic flow, a diversion road has been marked at the location.
Meanwhile, a large traffic jam has already formed, stretching several kilometres along the A13 towards Pétange.
