Poland, Lithuania, Latvia, and Estonia increased security around critical infrastructure amid warnings on August 10, 2026, concerning possible sabotage or staged attacks connected to regional tensions with Russia.
Lithuania deployed military personnel to protect important energy infrastructure. Latvia strengthened security around sites including the Daugava hydroelectric system and the Incukalns underground gas storage facility, while Polish authorities and infrastructure companies reviewed protection and supply arrangements.
Officials in the region said intelligence assessments had raised concern that an attack using Ukrainian-made drones could potentially be staged and attributed to Ukraine in an attempt to create uncertainty among NATO governments. No such operation had been publicly confirmed as having occurred.
Russia has denied allegations that it is preparing clandestine attacks against NATO countries and has described similar accusations as efforts to justify increased military activity against Russia.
The measures reflect broader concern about sabotage, drones, cyber operations, disinformation, and attacks on energy infrastructure during the Russia-Ukraine war. Poland and the Baltic states are NATO and European Union members located along the alliance's eastern region.
