Belgian, Dutch and Luxembourg police forces carried out a large-scale cross-border checkpoint operation to mark Benelux Day.[1] The joint operation entitled “From Knokke to Athus” ran on 4 and 5 September 2026.[2] In total, 968 vehicles and 382 people were checked, with controls also carried out on board international rail services.[1] The operation resulted in 48 criminal charges and seven arrests.[1]

The checks led to the seizure of approximately 500 grams of drugs, mainly cannabis, as well as 700 cartons of contraband cigarettes.[1] Two vehicles were also seized and police officers issued 28 fines for traffic offences, notably relating to taxi regulations and drink-driving.[1] Officers carried out joint checks at Luxembourg City’s main railway station.[1] Luxembourg and Belgian officers conducted joint patrols in the Grand Duchy, Luxembourg.[1]

The sweep was organised for Benelux Day 2026 to highlight intensive police cooperation within the Benelux.[2] It was presented as an application of the modernised Benelux Treaty on Police Cooperation in force since 2023, enabling cross-border pursuit, information exchange and joint operations.[2]
