Who is actually obstructing aircrafts’ family doctor in the Baltic?

.ON APRIL 29TH Finnair, Finland’s nationwide airline company, said that it would put on hold flights to the far eastern Estonian metropolitan area of Tartu for a month. Recently 2 planes were actually pushed to shift after their GPS indicators were actually interfered with. GPS playing has increased sharply in the Baltic region over recent two years.

Who lags it as well as just how risky could it be actually?
