Poland has been observing GPS disruptions over the Baltic Sea, Defense Minister Władysław Kosiniak-Kamysz said, adding they were “related to the actions of the Russian Federation, including sabotage actions.”

Polish media reported cases of GPS malfunction in the north of the country on Tuesday, including private drones flying away in unknown directions or losing connection.

“This may be Russia’s answer to the Baltops exercises,” Polish Vice Admiral Krzysztof Jaworski told Reuters on Tuesday, referring to NATO’s annual exercise in the Baltic Sea, being held this month.

Jaworski said the disruptions had become more intense since the start of the NATO exercise.

On Monday, a flight from Alicante in Spain to the northern Polish city of Bydgoszcz was redirected to Poznań in the west of Poland due to navigation problems, a Bydgoszcz airport spokesperson said, without identifying the airline.

“We are observing these disruptions. They are also observed over the Baltic Sea area by our allies in NATO countries - both in the Baltic states and the Nordic countries,” Kosiniak-Kamysz told journalists when asked about such incidents at a press conference about new helicopters.

“These actions are related, according to our sources, to the actions of the Russian Federation, also to sabotage actions.”

He did not elaborate on the sources.

**Rising sabotage threats **

Countries located on the Baltic Sea have reported numerous incidents since Russia invaded Ukraine in 2022, including power cable, telecom link and gas pipeline outages, and the NATO military alliance has boosted its presence in the region.

On Tuesday, Poland and the Baltic states signed a memorandum to boost the protection of critical energy infrastructure, with a special focus on shielding vulnerable underwater assets in the Baltic Sea, where a string of suspected sabotage attacks have been reported since Russia launched its full-scale invasion.

Last year, Estonia and Finland blamed Moscow for jamming GPS navigation devices in the region’s airspace.

Russia has repeatedly denied any wrongdoing.
