Drone activity triggers temporary closure of Liège Airport

On the evening of 04 November 2025, drone activity forced Liege Airport, a major cargo hub in eastern Belgium, to suspend operations twice within a few hours. According to Reuters and Euronews, the disruption tracked the same pattern seen that night at Brussels Airport: a first closure beginning around 8pm with a reopening near 9pm, followed by a second closure around 10pm before normal operations resumed around 11pm. Inbound flights were diverted and departures were held during the suspensions.

The Liege incident unfolded on the same evening as a separate drone disruption at Brussels Airport, where Belgian authorities reported dozens of cancellations and delays and where some passengers were left stranded overnight. Interior Minister Bernard Quintin said the country could not accept that its airports were disrupted by unauthorised drone flights and called for a coordinated, national response, as reported by Euronews.

The closures came amid a wider wave of drone incidents over Belgian airports and military sites in autumn 2025, including repeated incursions over the Kleine-Brogel airbase and earlier sightings linked to the Elsenborn training area, as documented by CNN. Defence Minister Theo Francken described the broader activity as the work of professionals seeking to destabilise the country, but officials have not publicly identified the operators or confirmed responsibility.

The operators behind the Liege closures remain unidentified, and no party has been shown to be responsible. Belgian officials have framed the autumn 2025 incursions as deliberate, professional, and aimed at destabilisation, language consistent with hybrid-warfare concerns voiced elsewhere in Europe, but this characterisation is an official assessment rather than proven attribution. The clustering of disruptions across Liege, Brussels, and military sites such as Kleine-Brogel suggests coordinated activity, yet intent and origin stay unverified. The incident fits a documented pattern without establishing who conducted it.
