A NATO warplane shot down a Ukrainian drone after it entered Estonian airspace. Ukraine blamed Russia for taking control of the drone, as well as others, and redirecting them toward NATO members.

Estonian Defense Minister Hanno Pevkur said Estonia had not granted its airspace to Ukrainian air forces, nor had Ukraine requested access.

Countries bordering Ukraine believe Russia is using electronic warfare to reprogram Ukrainian drones and send them into NATO airspace in an effort to divide the alliance, according to DW Brussels correspondent Teri Schultz.
