Russia says patrols near UK airspace were 'routine' - BBC News
Nato Secretary General Jens Stoltenberg said there had been a sharp increase in the number of times Russian planes were intercepted by members.
He said: "Last year, allied aircraft intercepted Russian planes over 400 times. Over 150 of these intercepts were conducted by Nato's Baltic air policing mission. That's about four times as many as in 2013. So we are staying vigilant."
It was only really a matter of time.
