Fighter jets on a NATO air defence mission have shot down a drone that entered the airspace of Latvia, a NATO and European Union member, early on Friday, Latvia's armed forces said on social media.
The armed forces also lifted an air threat alert for regions close to Russia.
Finland, another EU and NATO member which also shares a border with Russia, temporarily restricted areas for aviation and maritime traffic in the eastern Gulf of Finland, its defence forces said on social media, as a precautionary measure against possible drones.
Latvia's armed forces did not immediately provide details about the drone or its origin.
Countries neighbouring Russia and Ukraine issue air threat alerts and down drones from time to time as Moscow and Kyiv continue to exchange attacks after Russia's full-scale invasion of Ukraine in February 2022.
Overnight, Russia shot down 15 drones in the Leningrad region, close to Finland and Estonia and home to St Petersburg, the country second biggest city and a major export hub, regional governor Alexander Drozdenko said on social media early on Friday.
Russia's northern NATO neighbours are tightening security around dams, power plants and natural gas infrastructure in a sign of mounting concern that Moscow will stage a "false flag" attack on them using Ukrainian drones.
