Polish Defense Minister Antoni Macierewicz declared that Russian unmanned aerial vehicles (UAVs) had repeatedly violated country's airspace in the past, Sputnik News reports.
"These were drones. The incidents took place on the Polish-Russian border near Kaliningrad region. Fortunately, we have significantly strengthened the borders so during the last 2.5- 3 months such incidents were rare," Macierewicz stated
He added that the number of such incidents could be classified as numerous and expressed hope that Russian Aerospace Forces would be cautious in the airspace of NATO member states.
