Latvia has detected at least one drone flying in the country's airspace and NATO fighter jets were activated to combat the threat, the Baltic nation says, the latest in a series of such security incidents in the region.
The Latvian Armed Forces later announced on Thursday that the threat had ended, without providing further detail.
Ukraine has in recent months stepped up its long-range drone attacks on Russia, including in the Baltic Sea area, where several Ukrainian military drones have strayed into the airspace of NATO members Finland, Latvia, Lithuania and Estonia.
