Drones were spotted for the third consecutive night above the Kleine-Brogel military base in Belgium, prompting a helicopter deployment. The drones disappeared before military personnel could respond. Similar sightings occurred at other military sites and airports. An investigation is underway, with Belgian Defence Minister Theo Francken indicating a targeted mission. The motive behind the drone incursions remains unclear, raising concerns about security and prompting discussions among European leaders about protective measures.
