Who is actually congesting airplanes’ general practitioner in the Baltic?

.ON APRIL 29TH Finnair, Finland’s national airline company, pointed out that it would certainly suspend flights to the asian Estonian city of Tartu for a month. Last week 2 planes were obliged to shift after their GPS indicators were actually disrupted. General practitioner jamming has increased sharply in the Baltic area over the past two years.

Who lags it and also just how dangerous could it be?
