Repeated drone sightings over Belgium's Kleine Brogel air base; police investigate
Current state
Drones were reported over the Kleine Brogel air base in north-east Belgium on the nights of 31 October and 1 November 2025. A helicopter and police vehicles pursued the drone on Saturday without success, and a drone jammer could not intercept it. Belgium's defence minister said it was not a simple overflight but a clear command targeting the base, and later described the flights as a spying operation. Police opened an investigation.
