"There is a component of mental or psychological warfare from Russia, of intentionally redirecting the Ukrainian drones, basically hijacking them, to spook the European population to sort of create a more immediate experience of the risk of war, and of course also undermining the support for Ukraine," said Ondřej Ditrych to Euronews following the string of recent drone incursions into the EU airspace.

He added that in recent years, there is a clear pattern of escalation of these hybrid threats, "which spans a mosaic of disinformation, electoral interference, GPS jamming, arson nuclear intimidation and unidentified drones flying over or near airports and maritime infrastructure".
