A drone was spotted over the Kleine Brogel military base in Belgium on Sunday evening for the third night in a row, local media reported.
A helicopter was dispatched after military base personnel spotted the drone. But by then they had disappeared and flew north toward the Netherlands, state broadcaster VRT reported.
Drone sightings were also reported over a military base in Limburg province on Saturday and Friday. Belgian Defense Minister Theo Franken said Sunday morning that an investigation was underway.
“It was not a normal overflight, but a clear mission targeting Kleine Brogel,” Franken wrote in X.
This weekend, drone sightings also occurred in the military areas of Leopoldburg and Marche-en-Famenne, and at the airports of Durnay and Ostend.
Last month, 15 unidentified drones were spotted flying over the Elsenborn military base near the German border.
It remains unclear who is behind the drone and the motive for the intrusion.
However, in the wake of multiple suspicious drone sightings across Europe, discussions among European leaders are heating up over the feasibility of a so-called “drone wall” to protect the eastern tip of the continent from intrusion by drones believed to be from Russia.
