Drones have become a part of everyday life for many Ukrainians. Now, they’re showing up in the airspace of Baltic countries. On Wednesday, people in Lithuania’s capital, Vilnius, were instructed to take shelter when drone activity was detected near the border with Belarus. The day before, a NATO jet shot down a Ukrainian drone over southern Estonia. This followed an incident earlier this month when two drones hit an empty oil facility in Latvia.

It’s still not clear exactly how these drones are ending up in Baltic airspace, but some analysts believe the drones could be autonomously choosing their targets – a potential first in warfare.
