A mystery drone was shot down near Camp Reedo, a key U.S. Army base in Estonia, sparking alarm across NATO’s eastern flank. The unidentified UAV violated restricted airspace close to the Russian border, prompting allied forces to respond with anti-drone rifles. Though the wreckage was not recovered, the incident highlights Europe’s growing fears of Russian hybrid tactics after a surge in drone sightings across several NATO states. Estonia’s defense forces remain on high alert, while NATO considers a “drone wall” to protect its vulnerable airspace.
