"We have never provided extensive coverage to that but there were attempts of military unmanned aerial vehicles and other aircraft to illegally cross the border," said Vedernikov.
"All such ‘peaceful interaction’ was ‘flourishing’ even before the start of the special military operation," added the governor. "Clearly all that has aggravated further at present."
The Pskov oblast is located along Russia's border with NATO members Estonia and Latvia
In late October, two Russian Ka-52 attack helicopters were destroyed in an explosion at the Ostrov airbase in the Pskov oblast, according to the Chief Intelligence Directorate of the Ukrainian Defense Ministry. The explosion was allegedly caused by saboteurs placing the explosives near the helicopters.
The Ostrov airbase is located approximately 40 kilometers from the Russia's border.
