Meanwhile in Norway, two drones were spotted for Oslo. However, two foreign nationals were arrested for flying drones within the prohibited zone in central Oslo, reported Dagbladet, citing police officials.

Recent drone sightings over Europe

The recent drone sightings over Europe have been attributed to Russia as the Ukraine war escalates. Earlier this month, three NATO countries – Poland, Romania and Estonia reported Russian drones and jets in their respective airspace.

In response to these incursions, NATO jets were scrambled to assess the threat. Russia has denied responsibility and stated that the claims are “baseless provocations” against Moscow.
