Russia flew three fighter jets into neighbouring Estonia today in a 'reckless' and 'brazen' attempt to intimidate the Baltic state.
The powerful MiG-31 warplanes spent 12 minutes violating Estonian airspace as they conducted combat operations to test the country's defences.
The move sparked an emergency response from Nato, which sent in F-35 fighters to intercept the Russian aggression.
In further provocation by Vladimir Putin, two Russian jets also made a show of force over a Polish oil platform in the Baltic Sea, breaching its safety zone.
It comes as a former RAF commander last night called on Nato to draw a 'red line' in the sand - and hinted at shooting down future Russian jets.
