Estonia has accused neighbouring Russia of jamming GPS navigation devices in airspace above the Baltic states, echoing concerns from airlines that say they have been contending with such interference for months. Estonian Foreign Minister Margus Tsahkna's accusation, for which he provided no proof, followed Finnair's decision to pause flights to Tartu in eastern Estonia for one month due to GPS disturbances. There have been reports of a rise in GPS interference around the world, particularly since last year, raising fears of an increased risk of accidents if planes veer off-course.
