There were four cases of drones, violating the airspace over the Polish capital, recorded during 8 - 9 July NATO Summit in Warsaw, according to the head of the Polish Defense Ministry Antoni Macierewicz.
At the moment the drones are now at special services, writes Radio Poland. The drones were intercepted by the military counter-intelligence and internal security agency. To this end, Poland used Skyeye system, which includes unmanned aircrafts like Hermes, allowing to monitor an area in 5 km radius.
Macierewicz also said that it's not always possible to find out who was piloting the drones. He stressed that it is too early to draw conclusions whether the violations were intentional or had a criminal nature.
