Russia has denied violating NATO airspace after three of its military jets flew through the skies over Estonia for 12 minutes. Military experts say the move was aimed at determining NATO capabilities and testing the alliance's resolve.  It was the third incursion into NATO airspace by Russia this month. The statement released by Moscow said: "On September 19 of this year, three Russian MiG-31 fighter jets made a scheduled flight from Karelia to an airfield in the Kaliningrad region. "The flight was conducted in strict accordance with the International Rules for the Use of Airspace, without violating the borders of other states, as confirmed by objective monitoring means."
