Finland temporarily closed southern airspace and nearby sea routes on Tuesday, July 28 after authorities identified a possible threat from stray military drones, the country’s military announced.
The closure took effect just after 08:00 local time, and covered coastal areas near Kotka and Hamina in the eastern Gulf of Finland. Military teams cleared the zones by 10:20, and officials lifted the restrictions once they’d finished what the Finnish Defence Forces described as precautionary security work.
This represents the second time this month Finland has closed off this same patch of the Gulf. The first came on July 17, also tied to stray drone activity.
Both incidents are framed by long-range Ukrainian strikes on Russian targets near the border having knocked drones off course all year, and Finland isn’t alone in dealing with the fallout.
Estonia, Latvia and Lithuania have each reported drones wandering into their airspace, too, as part of a pattern that has alerted NATO’s northeastern flank through 2026.
In this instance, Finland’s military has confirmed little other than the restrictions being precautionary rather than a response to a confirmed breach.
Finland restricts access near Kotka and Hamina
The controlled zone ran from the Kaunissaari area west to waters near Hamina’s port, giving military teams room to intercept any drone that crossed into Finnish territory without warning.
Civilian traffic was cleared out first, including residents, vessel crews, aircraft, and anyone who might be in the way if countermeasures became necessary. Authorities also needed open operating space to track, approach, and safely neutralize any unmanned aircraft entering the country’s sovereign territory.
The Defence Forces ended the restrictions once officials determined that the immediate operational requirement no longer justified continued closures. However, the military withheld details about the intelligence that prompted the action, citing an active security operation.
A Finnish military spokesperson told Reuters the closure was meant to guarantee “safe countermeasures and the safety of bystanders” if a drone did stray into the area.
Drone activity raises wider NATO security concerns
Ukraine has increased long-range drone attacks against Russian military sites, energy facilities, transport links, and other strategic infrastructure targets. Several of those operations have sent drones drifting into Finnish, Estonian, Latvian and Lithuanian airspace, feeding a grouping worry that jamming or navigation failures could drag the war across NATO’s border.
Kyiv and a number of NATO governments point to Russian signal jamming as the culprit, arguing the nation is diverting drones off their intended paths. Moscow, however, rejects the accusation and instead accuses Ukraine of steering drones towards Russia’s neighbors on purpose during large overnight attacks.
Independent authorities have faced difficulty confirming responsibility because damaged aircraft often provide limited navigational and electronic evidence.
Russia has also reported hundreds of attempted drone attacks on Tuesday, July 28, hitting Moscow and the Leningrad region among other targets.
These repeated closures are becoming a routine cost of the war for the countries bordering it, representing recurrent hits to civilian access and a steady drain on military readiness across northern Europe.
