A Spanish military jet carrying Defence Minister Margarita Robles experienced a GPS disturbance while flying over Kaliningrad en route to Lithuania. The incident did not affect the flight due to military satellite signals. Similar GPS jamming incidents have been attributed to Russia, raising concerns among Nordic and Baltic nations about increased electronic interference. Bulgarian Prime Minister Rosen Zhelyazkov has also ordered an investigation into a related incident involving European Commission President Ursula von der Leyen's flight.
